Re: [C++ Pubnames Patch] Anonymous namespaces enclosed in named namespaces. (issue6343052)

[Dominique Dhumieres]

Hi Sterling,

On x86_64-apple-darwin10 the test fails with
FAIL: g++.dg/debug/dwarf2/pubnames-2.C scan-assembler .section\t.debug_pubnames
FAIL: g++.dg/debug/dwarf2/pubnames-2.C scan-assembler 
"_GLOBAL__sub_I__ZN3one3c1vE\\\\0"+[ \t]+[#;]+[ \t]+external name
FAIL: g++.dg/debug/dwarf2/pubnames-2.C scan-assembler .section\t.debug_pubtypes

(note that looking at the test I was expecting much more failures;-).
Grepping the assembly for 'debug_pubnames' and 'ZN3one3c1vE' returns

        .section __DWARF,__debug_pubnames,regular,debug
Lsection__debug_pubnames:

and

        .globl __ZN3one3c1vE
__ZN3one3c1vE:
        leal    __ZN3one3c1vE-L3$pb(%ebx), %eax
        leal    __ZN3one3c1vE-L8$pb(%ebx), %eax
        leal    __ZN3one3c1vE-L8$pb(%ebx), %eax
        .ascii "_ZN3one3c1vE\0" # DW_AT_linkage_name
        .long   __ZN3one3c1vE

So fixing the debug_pubnames failures for Darwin is fairly easy,
but I am not sure what to pick for ZN3one3c1vE.

Cheers,

Dominique
