- ??? The IBM rs6000/AIX assembler has a bug that causes bss block debug
- info to be occasionally lost. A simple example is this:
- int a; static int b;
- The commands `gcc -g -c tmp.c; dump -t tmp.o' gives
- [10] m 0x00000016 1 0 0x8f 0x0000 .bs
- [11] m 0x00000000 1 0 0x90 0x0000 .es
- ...
- [21] m 0x00000000 -2 0 0x85 0x0000 b:S-1
- which is wrong. The `b:S-1' must be between the `.bs' and `.es'.
- We can apparently work around the problem by forcing the text section
- (even if we are already in the text section) immediately before outputting
- the `.bs'. This should be fixed in the next major AIX release (3.3?). */
