Re: GNU as problem for aix4.3


I tried the patch and it works.

The object file generated is bigger than the previous one.
Objdump shows:

    Disassembly of section .data:

    000000000000002c <TOC>:
      2c: 41 00 00 00  bc 8,0,2c <TOC>

    000000000000002d <f>:
      2d: 00 00 00 00  .long 0x0

    0000000000000030 <f>:
      30: 00 00 00 00  .long 0x0
      34: 00 00 00 2c  .long 0x2c
      38: 00 00 00 00  .long 0x0

    000000000000003c <fp>:
      3c: 00 00 00 30  .long 0x30
      40: 00 00 00 00  .long 0x0
      44: 00 00 00 2c  .long 0x2c
      48: 00 00 00 00  .long 0x0

fp seems to have addition zeros.
So I changed your patch a little bit by putting it in the following
condition statement:

  if( symbol_get_tc (sym)->class == XMC_DS )
       frag_align (symbol_get_tc (sym)->align, 0, 0);

And I obtained the following objdump output:

    Disassembly of section .data:

    000000000000002c <TOC>:
      2c: 41 00 00 00  bc 8,0,2c <TOC>

    000000000000002d <f>:
      2d: 00 00 00 00  .long 0x0

    0000000000000030 <f>:
      30: 00 00 00 00  .long 0x0
      34: 00 00 00 2c  .long 0x2c
      38: 00 00 00 00  .long 0x0

    000000000000003c <fp>:
      3c: 00 00 00 30  .long 0x30
      40: 00 00 00 2c  .long 0x2c

I don't know if it's correct but it seems to work.
The only thing is that the symbol f is defined twice in the data
section.

Thanks for your help.
