This is usually handled in gcc/config/sol2.c (solaris_elf_asm_comdat_section, solaris_define_comdat_signature, solaris_code_end). I haven't yet checked why this doesn't trigger here. > Would something like: > --- gcc/dwarf2out.c 2011-07-27 23:25:36.000000000 +0200 > +++ gcc/dwarf2out.c 2011-07-28 16:43:29.181746188 +0200 > @@ -20872,6 +20872,7 @@ output_macinfo (void) > DEBUG_MACRO_SECTION_LABEL, > ref->lineno); > ASM_OUTPUT_LABEL (asm_out_file, label); > + ASM_OUTPUT_LABEL (asm_out_file, IDENTIFIER_POINTER (comdat_key)); > ref->code = 0; > free (CONST_CAST (char *, ref->info)); > ref->info = NULL; > fix it? Of course I'd prefer if this was limited to targets where the Probably. > assembler isn't capable of handling it correctly... Me too: this should be local to the Solaris port if at all possible. I won't argue if the need to explicitly define the signature symbols is a bug or just different from gas, though :-) Rainer
