32-bit && 64-bit Linux, GDB 5.3
>Description:
GDB 5.3 supports work with section .debug_macinfo.
During testing it has been found out that GDB 5.3 has problem with printing of predefined macro symbols.
It is not able to recognize debug information for them at all.
tets.c:
main()
{
int i = 10;
return;
}
GDB's output for this test is:
(gdb) b main
Breakpoint 1 at 0x8048abd: file test1.c, line 3.
(gdb) r
Starting program: /home1/sana/macro/tr/a.out
Breakpoint 1, main () at test1.c:3
3 int i = 10;
(gdb) macro expand __ELF__
expands to: __ELF__
(gdb) macro expand __gnu_linux__
expands to: __gnu_linux__
(gdb) p __ELF__
No symbol "__ELF__" in current context.
(gdb) p __gnu_linux__
No symbol "__gnu_linux__" in current context.
