--- Comment #12 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
ICE on the emutls-3.c testcase isn't related to emutls. Rather, the frontend
invokes decl_default_tls_model before attributes are processed, so the first
time around we miss the 'common' attribute when deciding the TLS access model.
The following cut-down testcase fails on x86 as well with -m32 -fpie:
__attribute__((common))
__thread int i;
int *f()
{
return &i;
}
Before the offending commit GCC compiled 'f' as if the attribute was ignored.
(on ELF targets combining TLS and COMMON is problematic if not undefined)
