*
GDB/MI does not keep the stack level, from what we expect. In gdb, the
highest stack is level 0 and lower stack as the highest level:
-stack-list-frames
^done,stack=[frame={level="0 ",addr="0x0804845b",func="main",file="hello.c",line="24"},
frame={level="1 ",addr="0x42017499",func="__libc_start_main",from="/lib/i686/libc.so.6"}]
-stack-list-frames
^done,stack=[frame={level="0 ",addr="0x08048556",func="main2",file="hello.c",line="58"},
frame={level="1 ",addr="0x08048501",func="main",file="hello.c",line="41"},
frame={level="2 ",addr="0x42017499",func="__libc_start_main",from="/lib/i686/libc.so.6"}]
This is of no use to us since the level is always "0". The level is necessary for example when
doing recursive calls to make a distinction between frames.
So in CDT this reverse the hidghest frame will have the highest number. In CDT:
stack=[frame={level="2 ",addr="0x0804845b",func="main",file="hello.c",line="24"},
frame={level="1 ",addr="0x42017499",func="__libc_start_main",from="/lib/i686/libc.so.6"}]
stack=[frame={level="3 ",addr="0x08048556",func="main2",file="hello.c",line="58"},
frame={level="2 ",addr="0x08048501",func="main",file="hello.c",line="41"},
frame={level="1 ",addr="0x42017499",func="__libc_start_main",from="/lib/i686/libc.so.6"}]
