--- Comment #3 from ebotcazou at gcc dot gnu dot org 2008-11-18 08:24 --- I'm not completely sure this is a bug in Sun as. If you consider the assembler code for my testcase produced by gcc: .global tsd .section.tbss,#alloc,#write,#tls .align 4 .type tsd, #tls_object .size tsd, 4 tsd: .skip 4 .common non_tsd,4,4 versus what Studio 12 cc produces: .section.bss,#alloc,#write .common non_tsd,4,4 .section.tbss,#alloc,#write,#tls .common tsd,4,4 you see that gcc lacks the section switching between non_tsd and tsd. OK, this makes sense, but I'd suggest discussing that under PR 29987. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38118

--- Comment #4 from jakub at gcc dot gnu dot org 2008-11-18 09:39 --- If you don't want to call it a bug, call it at least a misfeature. Given that Solaris as supports .tls_common directive, having .common directive behave differently depending on whether current section is .tbss (apparently comparison by name, flags don't matter and when in .tdata .common behaves normally) or not is very surprising. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38118
