CDT 8.3 - New and Noteworthy
+See What's new in CDT 8.3 on the CDT Wiki which may contain more recent information.
- -Build
+Toolchains
+- Language dialect options in GNU toolchain definition (Bug 404913).
+
Improved toolchain detection
-- Automatic detection of MinGW 64 bit (Bug 380598). -
- Detection of Visual Studio under Windows 7 64 bit (Bug 385608). -
- Recognize $PATH environment variable from workspace preferences for MinGW and Cygwin toolchains (Bug 384520). -
- Introduction of environment variables $MINGW_HOME and $CYGWIN_HOME that are recognized in preferences and project properties (Bug 403257, Bug 357442).
+
Scanner Discovery/Language Settings Providers
+- Use applicable options (such as language dialect) from build settings during discovery of built-in settings (Bug 404913). But note that to use options changed by user the built-in settings provider needs to be set as non-shared.
+
-
Scanner Discovery / Language Settings Providers
-- "Preprocessor Include Paths, Macros etc." property page now fully replaces older "Scanner Discovery" page. "Scanner Discovery" is now hidden by default (Bug 403405, Bug 407087).
+
Indexing
+Preferences for header variants
+New indexer preferences: +
+- Index all header variants +
- Index all header variants of specific headers
+
+These new preferences give the user more control over how the indexer handle variants of headers. By default, the indexer will index all variants of headers which do not have include guards or #pragma once. In certain cases, this strategy is not sufficient. To resolve this, the indexer can be configured to index all variants of headers, at the possible expense of indexing time. If the problematic headers are known, a comma separated list of headers can be specified and only those will be indexed for all variants.
-- Built-in Compiler Settings provider for MinGW is enabled by default now for MinGW toolchain (Bug 382422). -
- Added Built-in Compiler Settings provider for Cygwin (Bug 382423). -
-
-- Project-relative include paths representation was stabilized and now officially supported in UI (Bug 401734). -
- Support for project-relative paths for Build Output Providers (Bug 402023). -
- Changes in environment variables (preferences or project properties - as applicable) automatically trigger re-discovery (Bug 403406). -
- Number of changes to support compatibility with older methods to provide include paths for indexer, namely pathEntryContainers, contributed ScannerInfo entries (Bug 401961, Bug 398056, Bug 392966). -
- Fixed compatibility issues related to import older projects (Bug 393641). -
Makefile Editor
-- GNU Makefile functions highlighting fixed (Bug 406911). -
- Bracket matching (Bug 405279). -
-
-- Content assist for automatic variables (Bug 407169). -
-
-- Highlight for conditional variable assignment (Bug 406596). -
- Proper colorization of escaped # (Bug 404599). -
Misc
-- Ability to specify local includes for indexer, as in [#include "header.h"] as opposed to system includes [#include <header.h>] (Bug 388368). -
- Fixed some bugs related to storing environment variables, such as silently ignoring removals or additions (Bug 348781, Bug 355488). -
- Improved performance in certain areas (Bug 405643, Bug 405638, Bug 405744, Bug 407483). -
- User documentation for Scanner Discovery updated including property page "Preprocessor Includes, Macros" (Bug 409392). -
Debug
-Enhanced Expressions
-The Expressions view has been extended to allow the user to manually create enhanced-expressions. Enhanced-expressions define a set of expressions which can be easily described using glob-pattern matching. The user specifies an enhanced-expression by prefixing it with '='. For example: -
-- pattern-matched sorted groups of local variables, where the symbols * [] ? can be used e.g., -
=v?r -- Will show local variables starting with a 'v' and ending with 'r' with a single character in between -=* -- Will show all local variables of the selected stack frame in sorted order (the '=' is optional for this expression, i.e., '*') -=*x -- Will show local variables ending with 'x' -
-- array ranges including glob-expressions -
=array[30-40] -- Will show array elements from 30 to 40 -=array[1-5,20,30-31] -- Will show array elements from 1 to 5, 20 and 30 to 31 -=array?[1-5] -- Will show array elements from 1 to 5 for any array starting with 'array' followed by a single character -
-- pattern-matched sorted registers groups, where the symbols * [] ? can be used e.g., -
=$e?x -- Will show all registers starting with 'e' and ending with 'x' with a single character in between -=$* -- Will show all registers (the '=' is optional for this expression, i.e., '$*') -=$*x -- Will show registers ending with 'x' -=$st[3-5] -- Will show registers $st3, $st4, $st5 -
-- semi-colon-separated, individually sorted groups of expressions, e.g, -
var1; var2 -- Will create a group containing both var1 and var2 -$eax; var1 -- Will show a group containing register $eax and variable var1 -var1; =$e* -- Will show a group containing variable var1 as well as all registers starting with 'e' -
-This feature allows to quickly define multiple expressions that interest the user. Because groups are created from these special expressions, they can be collapsed when uninteresting and re-expanded later, without having to be re-entered by the user. -
-This feature was completed on July 10th, 2012 and updated for local variables on December 19th, 2012. For details see Bug 381754 and Bug 394408. -
Note that the comma (,) is not allowed as a group separator as it is used within valid expressions that use templates (e.g., ((((((class std::_Vector_base<int, std::allocator<int> >) v))._M_impl))._M_start)). -
-OS Resources View
-CDT has a new view called "OS Resources". This view will display different information about the resources of the operating system. For example, it can give a list of all processes running on the target. The view will display the information as provided by GDB. -
-As of writing, GDB supported the following information: -
-Processes - Listing of all processes -Process groups - Listing of all process groups -Threads - Listing of all threads -File descriptors - Listing of all file descriptors -Sockets - Listing of all internet-domain sockets -Shared-memory regions - Listing of all shared-memory regions -Semaphores - Listing of all semaphores -Message queues - Listing of all message queues -Kernel modules - Listing of all loaded kernel modules -
-
-
Notes: -- For performance reasons, the view is not automatically refreshed. Press the Refresh button on the the view toolbar to fetch the latest information. Hovering over this Refresh button will display the time at which the information was last obtained. -
- Columns can be re-sized. -
- Columns can be removed or added using the view menu. -
- Entries can be ordered by column by pressing on the column header. -
- When doing debugging of a remote target, the information in the view pertains to the remote target. -
This feature requires GDB 7.5 and higher. Furthermore, as of GDB 7.5, this feature only works for Linux. -
This feature was completed on September 20th, 2012. For details see Bug 360314. -
-Breakpoint Filtering
-The CDT has enhanced the standard behavior of the "Show Breakpoints Supported by Selected Target" option of the Breakpoints view. Using this option with the CDT will now only show breakpoints that are actually applicable to the current debug session. Therefore, when debugging a C/C++ application, the user will not be bothered with the breakpoints set in the code of an another C/C++ application. -
-For backwards-compatibility, a preference is provided to revert this new behavior to the original one. The original behavior of this option is to have the Breakpoints view show all breakpoints that are of the same type as the current debug session. For example, if debugging Java, only Java breakpoints would be shown, and if debugging C/C++ only C/C++ breakpoints would be shown. This preference can be found under "C/C++ -> Debug -> GDB -> Use aggressive breakpoint filtering". -
This feature was completed on October 26th, 2012. For details see Bug 360735. -
-Enhanced GDB console support
-CDT is being improved to update its views with any change made to GDB by the user from the GDB console. Updates are being added gradually and the final goal is to allow the user to perform any command from the GDB console, and have CDT stay synchronized with the changes. -
-Breakpoints, watchpoints and tracepoints
-Breakpoints, watchpoints or tracepoints set from the GDB console are now shown in the Breakpoints view. All breakpoint related GDB commands are supported and synchronized with the UI. No support for catchpoints yet. This feature requires GDB 7.4 or higher. -
This feature was completed on November 29th, 2012. For details see Bug 392512. -
-Memory and variables
-Memory and variables modified from the GDB console are now updated in the Memory, Memory Browser, Variables and Expressions views. This feature requires GDB 7.6 or higher. -
This feature was completed on January 26th, 2013. For details see Bug 397715. -
-Reverse debugging state
-CDT will now properly update the status of reverse debugging if its state is modified through the GDB console. This feature requires GDB 7.6 or higher. -
This feature was completed on January 31st, 2013. For details see Bug 399163 -
-Breakpoint actions to control reverse debugging
-It's now possible to control the enabling, disabling and toggling of the reverse debugging mode, through breakpoint actions. The reverse debugging mode can be useful to debug, but has a significant performance cost when enabled. Using the new breakpoint action to enable the reverse debug mode, one can program a breakpoint to enable that mode in the vicinity of the suspected source code. That way, until that point is reached, no performance impacts are felt. -
To use this feature, right-click on a breakpoint and select "Breakpoint Properties". Then in the left page, chose "Actions". Then click "New". In the new dialog, select the Action Type "Reverse Debug Action". Then chose if the action should enable, disable or toggle the reverse debug mode. Finally chose a name for the action. When done, click "Ok" -
-The newly created action will appear in the list of available actions, that can be attached to any breakpoint To attach it to the current breakpoint, click on "Attach". -
-Note: For the reverse debug breakpoint actions to work, reverse debugging must be available in the current debug session. For instance, it will not work if the "non-stop" mode is active. -
This feature was completed on December 13th, 2012. For details see Bug 365776. -
-Floating Point renderer has been added to the memory package
-A floating point render has been added to the memory package. So now there is the Traditional renderer and a Floating Point renderer available. This render allows display and editing of the floating point values. Since it originated from the Traditional render, it's workflow and style are similar. There is no ASCII data pane display, since this did not seem to make much sense with floating point data. -
-This feature was completed on November 16th, 2012 as part of Bug 394509. -
-Debugging multiple processes within one debug session
-Debugging a new executable in the same debug session has been improved for GDB versions starting from 7.2. "Debug New Executable" action has been added to the context menu of the Debug view. -
+Debug
+Threads displayed by creation order in the Debug view
+For a multi-threaded program, the different threads are now shown in the order they were created during execution. Not only is that order more intuitive, it allows for the selection in the Debug view to be more stable. This enhancement was completed on January 13th, 2014. For details see Bug 412547. +
-The dialog for specifying an executable to debug for local sessions has been changed. -
-
-The ability to debug a remote executable using gdbserver has been added. -
-This feature was completed on January 25th, 2013. For details see Bug 344890.
-
Load information in the Multicore Visualizer - CPU/core load meters
-The Multicore Visualizer view has been enhanced to support system load monitoring, in the form of graphical load meters, showing the load of the system being debugged (local or remote). This works only on Linux targets for now. By default this feature is disabled, as it may cause a bit of increased load when remote-debugging. Here is what it looks-like, when enabled: -
-When enabled and space permits, a load meter is displayed for each core and also one for each CPU, that shows the average load for all contained cores. -
To enable the load meters, one has to use the context menu of the Multicore Visualizer; right-click on the visualizer, go into the "Load Meters" sub-menu and select "Enable Load Meters" : -
-It's also possible to choose the load meters refresh interval. When the load meters are enabled, a "Refresh Speed" entry is added to the Load Meters sub-menu. There you have a choice of three refresh speeds. Selecting one makes it take effect. -
+Support for multi-process debugging in Memory views
+The Memory view and Memory Browser view now support multi-process debugging. Beyond properly refreshing their content based on the currently selected process, the user can now define different memory addresses to look at for each process being debugged. This work was a contribution from Alvaro Sanchez-Leon on January 15th, 2014. For details see Bug 250323. +
-
-This feature was completed on February 28th, 2013. For details see Bug 396268. -Edit Tracepoint on Create
-It is no longer necessary to first create a CDT Tracepoint, then edit its properties. Properties such as enabled, pass count, condition, can be set while creating the tracepoint. -
There are different methods to open the properties dialog before creating the Tracepoint. First, using the editor popup menu by right-clicking on the editor gutter, one must set the Breakpoint Type to "C/C++ Tracepoints". -
-- Add Breakpoint action.
-
- Select the Add Breakpoint... menu item. -
- This brings up the tracepoint properties dialog for a line tracepoint pre-filled with the tracepoint's location. -
- Control-Double Click
-
- Hold the Control key while double-clicking on the editor gutter. -
- This brings up the breakpoint properties dialog for a line breakpoint pre-filled with the breakpoints location. -
Step Into Selection
-With the DSF debugger it is now possible to select a function to step into.
-
-The selected method can be in a different line than the one under execution
-The two main methods to do this are -- Using the context menu -
Select a method, right-click and select "Step Into Selection"
-or use the short key Ctrl+F5 -
-
-- Using the hyper link navigation -
Press Ctrl-Alt, hover over a function and mouse click on it -
-NOTE: This first implementation runs to the selected line, steps into its methods and stops when a method is entered having the same name and number of arguments of the selected method i.e. Argument types are not validated at this point. -
This feature was completed on May 1st, 2013. For details see Bug 244865. -
-Multicore Visualizer enhanced selection and filtering
-The multicore visualizer has been enhanced so that it's now possible to select CPUs and cores, in addition to threads. The previous selection methods still work (ctrl-left-click add-to-selection, left-click and drag, etc), but now are also applicable to CPU and core graphical objects. -
-This feature was completed on April 26th, 2013. For details see Bug 404894.
-Building on the enhanced selection, it's now also possible to filter what is shown in the multicore visualizer. This is especially useful in cases where there are many CPUs/cores/threads, and one wants to concentrate on a subset. To filter the view, first select the graphical elements you want to keep, then from the context menu, chose "Filter to selection". The selected graphical elements will be shown, along with any parent objects; for instance a thread will be shown in its core and CPU. The filter stays in place until cleared, using the context menu "Clear filter". -
-This feature was completed on May 6th, 2013. For details see Bug 405390.
-Process exit code shown in console
-When a process completes execution normally, its exit code is shown in the title of that process' console. If the process is terminated or disconnected by the user, no exit code will be shown. -
-Note that if there is no process console, then no exit code can be displayed. This affects remote debugging and attach debugging. We hope to address this in the next release of CDT. -
This feature was completed on May 6th, 2013. For details see Bug 402054. +
Enhanced support for multi-process debugging in Registers view
+The Registers view now supports debugging processes with a different set of registers. For example, the registers of the selected process will properly be displayed when debugging both a 32-bit process and a 64-bit process. This work was a contribution from Alvaro Sanchez-Leon on September 29th, 2013. For details see Bug 418176. +
+
+
+
-
Important Notes
-Although CDT 8.2 is meant to be a backwards-compatible release, the following exceptions should be noted. +
Register view is now stack-frame-specific
+The Registers view will now update each time a different stack-frame is selected. The view will show the content of the registers as they were for the selected frame, when the method call was done which caused the creation of the next stack-frame. This work was a contribution from Alvaro Sanchez-Leon on September 27th, 2013. For details see Bug 323552. +
+
+

-
- The package org.eclipse.cdt.dsf.gdb.multicorevisualizer.internal was made API by mistake when first released. It has now been officially marked internal. Note that the package has always had the word 'internal' in its name. We don't believe there are any extenders to this package yet. -
+Basic support of Multicore Visualizer in all-stop mode
+The Multicore Visualizer now displays properly in all-stop mode, with all its features available when the program is suspended, while still updating thread creation/termination when the program is running. This enhancement was completed on August 15th, 2013. For details see Bug 409965 +

Variable substitution for GDB command file path
+It is now possible to use eclipse variables within the specified path of the GDB command file. This allows to have project-specific GDB command files. For example ${project_loc}/project.gdbinit. This feature was completed July 23rd, 2013. For details see Bug 413373 +
+
+
- +
Project-less debugging is now supported on the Windows platform
+Project-less debugging now works as expected on Windows. This enhancement was completed on August 10th, 2013. For details see Bug 344470 +
+
+Detection of target disconnection
+When doing remote debugging, if the connection to the target is lost, the debug session will be cleanly terminated. Previously, some situations could lead to a debug session that lost its connection but remained active using the host machine instead; these cases have been fixed. This enhancement was completed on January 8th, 2014. For details see Bug 422586 +
+Qt Support (preview)
+Work continues on CDT's support for Qt. For CDT 8.3, this includes the following. Note that we still consider this a preview release until CDT 8.4 where we'll clean up usability issues around setting up CDT to work with Qt and hopefully some better qmake and QML support. +
+New Project Wizard
+We have revamped the new project wizard for Qt. It's available under Makefile projects as Qt5 Hello World project. It uses a top level Makefile to drive the calls to qmake and make on the qmake generated QtMakefile. The project doesn't do a shadow build but an in project build to keep things simple for now. +
+Syntax Highlighting
+Syntax highlighting is provided for Qt macros inluding 'signal', 'slot'. +
+Indexing and Search
+The CDT indexer now captures several Qt "extensions" to C++. This include slots and signals as well as properties and related functions. This enables searching for references to slots and signals in connect calls. +
+Content Assist
+In connect calls, content assist is provided to show valid slot and signal functions for the objects you are connecting. Content assist templates are also provided for QObject class declarations and Q_PROPERTY declarations. +
+Codan Semantic Checkers
+Semantic checkers are provided to ensure that the parameters to the connect call are valid. +

Editor
+Organize Includes Command
+The Organize Includes command is similar to Organize Imports in Java. It adds missing include statements, removes unnecessary ones, and reorders includes according to user preferences. +
+When determining which header files must be included the Organize Includes command follows the "Include What You Use" rule. See Why Include What You Use? and What Is a Use?. +
+Build
+Console
+- Line wrap option on the console (Bug 199605). +
+
+Improved toolchain detection
+- Automatic detection of MinGW 64 bit (Bug 380598). +
- Detection of Visual Studio under Windows 7 64 bit (Bug 385608). +
- Recognize $PATH environment variable from workspace preferences for MinGW and Cygwin toolchains (Bug 384520). +
- Introduction of environment variables $MINGW_HOME and $CYGWIN_HOME that are recognized in preferences and project properties (Bug 403257, Bug 357442). +
+
+Scanner Discovery / Language Settings Providers

Debug
+Enhanced Expressions
+The Expressions view has been extended to allow the user to manually create enhanced-expressions. Enhanced-expressions define a set of expressions which can be easily described using glob-pattern matching. The user specifies an enhanced-expression by prefixing it with '='. For example: +
+- pattern-matched sorted groups of local variables, where the symbols * [] ? can be used e.g., +
=v?r -- Will show local variables starting with a 'v' and ending with 'r' with a single character in between +=* -- Will show all local variables of the selected stack frame in sorted order (the '=' is optional for this expression, i.e., '*') +=*x -- Will show local variables ending with 'x' +
+- array ranges including glob-expressions +
=array[30-40] -- Will show array elements from 30 to 40 +=array[1-5,20,30-31] -- Will show array elements from 1 to 5, 20 and 30 to 31 +=array?[1-5] -- Will show array elements from 1 to 5 for any array starting with 'array' followed by a single character +
+- pattern-matched sorted registers groups, where the symbols * [] ? can be used e.g., +
=$e?x -- Will show all registers starting with 'e' and ending with 'x' with a single character in between +=$* -- Will show all registers (the '=' is optional for this expression, i.e., '$*') +=$*x -- Will show registers ending with 'x' +=$st[3-5] -- Will show registers $st3, $st4, $st5 +
+- semi-colon-separated, individually sorted groups of expressions, e.g, +
var1; var2 -- Will create a group containing both var1 and var2 +$eax; var1 -- Will show a group containing register $eax and variable var1 +var1; =$e* -- Will show a group containing variable var1 as well as all registers starting with 'e' +
+This feature allows to quickly define multiple expressions that interest the user. Because groups are created from these special expressions, they can be collapsed when uninteresting and re-expanded later, without having to be re-entered by the user. +
+This feature was completed on July 10th, 2012 and updated for local variables on December 19th, 2012. For details see Bug 381754 and Bug 394408. +
Note that the comma (,) is not allowed as a group separator as it is used within valid expressions that use templates (e.g., ((((((class std::_Vector_base<int, std::allocator<int> >) v))._M_impl))._M_start)). +
+OS Resources View
+CDT has a new view called "OS Resources". This view will display different information about the resources of the operating system. For example, it can give a list of all processes running on the target. The view will display the information as provided by GDB. +
+As of writing, GDB supported the following information: +
+Processes - Listing of all processes +Process groups - Listing of all process groups +Threads - Listing of all threads +File descriptors - Listing of all file descriptors +Sockets - Listing of all internet-domain sockets +Shared-memory regions - Listing of all shared-memory regions +Semaphores - Listing of all semaphores +Message queues - Listing of all message queues +Kernel modules - Listing of all loaded kernel modules +
+
+
Notes: +- For performance reasons, the view is not automatically refreshed. Press the Refresh button on the the view toolbar to fetch the latest information. Hovering over this Refresh button will display the time at which the information was last obtained. +
- Columns can be re-sized. +
- Columns can be removed or added using the view menu. +
- Entries can be ordered by column by pressing on the column header. +
- When doing debugging of a remote target, the information in the view pertains to the remote target. +
This feature requires GDB 7.5 and higher. Furthermore, as of GDB 7.5, this feature only works for Linux. +
This feature was completed on September 20th, 2012. For details see Bug 360314. +
+Breakpoint Filtering
+The CDT has enhanced the standard behavior of the "Show Breakpoints Supported by Selected Target" option of the Breakpoints view. Using this option with the CDT will now only show breakpoints that are actually applicable to the current debug session. Therefore, when debugging a C/C++ application, the user will not be bothered with the breakpoints set in the code of an another C/C++ application. +
+For backwards-compatibility, a preference is provided to revert this new behavior to the original one. The original behavior of this option is to have the Breakpoints view show all breakpoints that are of the same type as the current debug session. For example, if debugging Java, only Java breakpoints would be shown, and if debugging C/C++ only C/C++ breakpoints would be shown. This preference can be found under "C/C++ -> Debug -> GDB -> Use aggressive breakpoint filtering". +
This feature was completed on October 26th, 2012. For details see Bug 360735. +
+Enhanced GDB console support
+CDT is being improved to update its views with any change made to GDB by the user from the GDB console. Updates are being added gradually and the final goal is to allow the user to perform any command from the GDB console, and have CDT stay synchronized with the changes. +
+Breakpoints, watchpoints and tracepoints
+Breakpoints, watchpoints or tracepoints set from the GDB console are now shown in the Breakpoints view. All breakpoint related GDB commands are supported and synchronized with the UI. No support for catchpoints yet. This feature requires GDB 7.4 or higher. +
This feature was completed on November 29th, 2012. For details see Bug 392512. +
+Memory and variables
+Memory and variables modified from the GDB console are now updated in the Memory, Memory Browser, Variables and Expressions views. This feature requires GDB 7.6 or higher. +
This feature was completed on January 26th, 2013. For details see Bug 397715. +
+Reverse debugging state
+CDT will now properly update the status of reverse debugging if its state is modified through the GDB console. This feature requires GDB 7.6 or higher. +
This feature was completed on January 31st, 2013. For details see Bug 399163 +
+Breakpoint actions to control reverse debugging
+It's now possible to control the enabling, disabling and toggling of the reverse debugging mode, through breakpoint actions. The reverse debugging mode can be useful to debug, but has a significant performance cost when enabled. Using the new breakpoint action to enable the reverse debug mode, one can program a breakpoint to enable that mode in the vicinity of the suspected source code. That way, until that point is reached, no performance impacts are felt. +
To use this feature, right-click on a breakpoint and select "Breakpoint Properties". Then in the left page, chose "Actions". Then click "New". In the new dialog, select the Action Type "Reverse Debug Action". Then chose if the action should enable, disable or toggle the reverse debug mode. Finally chose a name for the action. When done, click "Ok" +
+The newly created action will appear in the list of available actions, that can be attached to any breakpoint To attach it to the current breakpoint, click on "Attach". +
+Note: For the reverse debug breakpoint actions to work, reverse debugging must be available in the current debug session. For instance, it will not work if the "non-stop" mode is active. +
This feature was completed on December 13th, 2012. For details see Bug 365776. +
+Floating Point renderer has been added to the memory package
+A floating point render has been added to the memory package. So now there is the Traditional renderer and a Floating Point renderer available. This render allows display and editing of the floating point values. Since it originated from the Traditional render, it's workflow and style are similar. There is no ASCII data pane display, since this did not seem to make much sense with floating point data. +
+This feature was completed on November 16th, 2012 as part of Bug 394509. +
+Debugging multiple processes within one debug session
+Debugging a new executable in the same debug session has been improved for GDB versions starting from 7.2. "Debug New Executable" action has been added to the context menu of the Debug view. +
+
+The dialog for specifying an executable to debug for local sessions has been changed. +
+
+The ability to debug a remote executable using gdbserver has been added. +
+This feature was completed on January 25th, 2013. For details see Bug 344890. +
+
+Load information in the Multicore Visualizer - CPU/core load meters
+The Multicore Visualizer view has been enhanced to support system load monitoring, in the form of graphical load meters, showing the load of the system being debugged (local or remote). This works only on Linux targets for now. By default this feature is disabled, as it may cause a bit of increased load when remote-debugging. Here is what it looks-like, when enabled: +
+When enabled and space permits, a load meter is displayed for each core and also one for each CPU, that shows the average load for all contained cores. +
To enable the load meters, one has to use the context menu of the Multicore Visualizer; right-click on the visualizer, go into the "Load Meters" sub-menu and select "Enable Load Meters" : +
+It's also possible to choose the load meters refresh interval. When the load meters are enabled, a "Refresh Speed" entry is added to the Load Meters sub-menu. There you have a choice of three refresh speeds. Selecting one makes it take effect. +
+
+
+This feature was completed on February 28th, 2013. For details see Bug 396268. +Edit Tracepoint on Create
+It is no longer necessary to first create a CDT Tracepoint, then edit its properties. Properties such as enabled, pass count, condition, can be set while creating the tracepoint. +
There are different methods to open the properties dialog before creating the Tracepoint. First, using the editor popup menu by right-clicking on the editor gutter, one must set the Breakpoint Type to "C/C++ Tracepoints". +
+- Add Breakpoint action.
+
- Select the Add Breakpoint... menu item. +
- This brings up the tracepoint properties dialog for a line tracepoint pre-filled with the tracepoint's location. +
- Control-Double Click
+
- Hold the Control key while double-clicking on the editor gutter. +
- This brings up the breakpoint properties dialog for a line breakpoint pre-filled with the breakpoints location. +
Step Into Selection
+With the DSF debugger it is now possible to select a function to step into.
+
+The selected method can be in a different line than the one under execution
+The two main methods to do this are +- Using the context menu +
Select a method, right-click and select "Step Into Selection"
+or use the short key Ctrl+F5 +
+
+- Using the hyper link navigation +
Press Ctrl-Alt, hover over a function and mouse click on it +
+NOTE: This first implementation runs to the selected line, steps into its methods and stops when a method is entered having the same name and number of arguments of the selected method i.e. Argument types are not validated at this point. +
This feature was completed on May 1st, 2013. For details see Bug 244865. +
+Multicore Visualizer enhanced selection and filtering
+The multicore visualizer has been enhanced so that it's now possible to select CPUs and cores, in addition to threads. The previous selection methods still work (ctrl-left-click add-to-selection, left-click and drag, etc), but now are also applicable to CPU and core graphical objects. +
+This feature was completed on April 26th, 2013. For details see Bug 404894. +
+Building on the enhanced selection, it's now also possible to filter what is shown in the multicore visualizer. This is especially useful in cases where there are many CPUs/cores/threads, and one wants to concentrate on a subset. To filter the view, first select the graphical elements you want to keep, then from the context menu, chose "Filter to selection". The selected graphical elements will be shown, along with any parent objects; for instance a thread will be shown in its core and CPU. The filter stays in place until cleared, using the context menu "Clear filter". +
+This feature was completed on May 6th, 2013. For details see Bug 405390. +
+Process exit code shown in console
+When a process completes execution normally, its exit code is shown in the title of that process' console. If the process is terminated or disconnected by the user, no exit code will be shown. +
+Note that if there is no process console, then no exit code can be displayed. This affects remote debugging and attach debugging. We hope to address this in the next release of CDT. +
This feature was completed on May 6th, 2013. For details see Bug 402054. +
+Important Notes
+Although CDT 8.2 is meant to be a backwards-compatible release, the following exceptions should be noted. +
+- The package org.eclipse.cdt.dsf.gdb.multicorevisualizer.internal was made API by mistake when first released. It has now been officially marked internal. Note that the package has always had the word 'internal' in its name. We don't believe there are any extenders to this package yet. +
