I'm too lazy to writing duplicate code to handle this. The following works but is a bit ugly. Meh, the builtins stuff _is_ ugly (adding extra flags to bdesc would be nicer but a lot of boiler-plate work and the question is whether all the rest is "nice enough" or in need of serious overhaul anyway...) diff --git a/gcc/config/i386/i386-builtins.c b/gcc/config/i386/i386-builtins.c index 128bd39816c..fa05cd6cf65 100644 --- a/gcc/config/i386/i386-builtins.c +++ b/gcc/config/i386/i386-builtins.c @@ -521,7 +521,17 @@ ix86_init_mmx_sse_builtins (void) continue; ftype = (enum ix86_builtin_func_type) d->flag; - def_builtin (d->mask, d->mask2, d->name, ftype, d->code); + if (d->code == IX86_BUILTIN_MASKLOADPD + || d->code == IX86_BUILTIN_MASKLOADPS + || d->code == IX86_BUILTIN_MASKLOADPD256 + || d->code == IX86_BUILTIN_MASKLOADPS256 + || d->code == IX86_BUILTIN_MASKLOADD + || d->code == IX86_BUILTIN_MASKLOADQ + || d->code == IX86_BUILTIN_MASKLOADD256 + || d->code == IX86_BUILTIN_MASKLOADQ256) + def_builtin_pure (d->mask, d->mask2, d->name, ftype, d->code); + else + def_builtin (d->mask, d->mask2, d->name, ftype, d->code); } BDESC_VERIFYS (IX86_BUILTIN__BDESC_SPECIAL_ARGS_LAST, IX86_BUILTIN__BDESC_SPECIAL_ARGS_FIRST,
