[AIX] discard the label in the csect of function description and use qualname for linkage
SUMMARY:
SUMMARY
for a source file "test.c"
void foo() {};
llc will generate assembly code as (assembly patch)
.globl foo
.globl .foo
.csect foo[DS]
foo:
.long .foo
.long TOC[TC0]
.long 0
and symbol table as (xcoff object file)
[4] m 0x00000004 .data 1 unamex foo
[5] a4 0x0000000c 0 0 SD DS 0 0
[6] m 0x00000004 .data 1 extern foo
[7] a4 0x00000004 0 0 LD DS 0 0
After first patch, the assembly will be as
.globl foo[DS] # -- Begin function foo
.globl .foo
.align 2
.csect foo[DS]
.long .foo
.long TOC[TC0]
.long 0
and symbol table will as
[6] m 0x00000004 .data 1 extern foo
[7] a4 0x00000004 0 0 DS DS 0 0
Change the code for the assembly path and xcoff objectfile patch for llc.
