The -mstackrealign option and the force_align_arg_pointer attribute from this
patch have both been added; -mstackrealign doesn't work with
__attribute__((target(""))) though:
$ cat 6737.c && /usr/local/bin/gcc -c 6737.c
void foo(void) __attribute__((__target__("stackrealign")));
void foo(void)
{
// ...
}
void __attribute__((force_align_arg_pointer)) bar(void *baz)
{
// ...
}
6737.c:1:1: error: attribute(target("stackrealign")) is unknown
void foo(void) __attribute__((__target__("stackrealign")));
