This commit breaks the build of glibc for powerpc64le-linux-gnu. Compile
the following code with -O2 -mlong-double-128 -mabi=ibmlongdouble and I
get the error
opts-bug.c:8:1: error: '-mabi=ibmlongdouble' requires '-mlong-double-128'
8 | {
| ^
which is clearly nonsensical, since -mlong-double-128 is passed.
extern unsigned long int x;
extern float f (float);
extern __typeof (f) f_power8;
extern __typeof (f) f_power9;
extern __typeof (f) f __attribute__ ((ifunc ("f_ifunc")));
static __attribute__ ((optimize ("-fno-stack-protector"))) __typeof (f) *
f_ifunc (void)
{
__typeof (f) *res = x ? f_power9 : f_power8;
return res;
}
