32-bit and 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 macro symbols whose value is string without quotes.
But it is usual parctice to use such values.
tets.c:
#define PREFIX small
main()
{
int PREFIX_i = 10, PREFIX_j;
PREFIX_j = abs(PREFIX_i);
return;
}
GDB's output for this test is:
This GDB was configured as "i686-pc-linux-gnu"...
(gdb) b main
Breakpoint 1 at 0x8048aef: file test2.c, line 4.
(gdb) r
Starting program: /home1/sana/macro/tr/a.out
Breakpoint 1, main () at test2.c:4
4 int PREFIX_i = 10, PREFIX_j;
(gdb) p PREFIX
No symbol "small" in current context.

>How-To-Repeat:
Unfortunately current Intel compiler does not generate debug information for macros. But this feature will be included in compiler 8.0.
