All fails I had were on sysdeps/powerpc/fpu/get-rounding-mode.h:30 which
is:
27 static inline int
28 get_rounding_mode (void)
29 {
30 return _FPU_GET_RC ();
31 }
And that in turn is defined as:
83 # ifdef _ARCH_PWR9
84 # define _FPU_GET_RC() _FPU_GET_RC_ISA300()
85 # elif defined __BUILTIN_CPU_SUPPORTS__
86 # define _FPU_GET_RC()»»···»···»···»···»···»···\
87 ({fpu_control_t __rc;»»···»···»···»···»···»···\
88 __rc = __glibc_likely (__builtin_cpu_supports ("arch_3_00"))»···\
89 ? _FPU_GET_RC_ISA300 ()»··»···»···»···»···»···\
90 : _FPU_GETCW (__rc) & _FPU_MASK_RC;»··»···»···»···\
91 __rc;»··»···»···»···»···»···»···»···\
92 })
93 # else
94 # define _FPU_GET_RC()»»···»···»···»···»···\
95 ({fpu_control_t __rc = _FPU_GETCW (__rc) & _FPU_MASK_RC;»·\
96 __rc;»··»···»···»···»···»···»···\
97 })
98 # endif
In assembly layout that is on
beq 0x...
> mffsl 0
mfvsrd r8,vs0
That seems like this code:
75 # define _FPU_GET_RC_ISA300()»··»···»···»···»···»···\
76 ({union { double __d; unsigned long long __ll; } __u;»»···»···\
77 __asm__ __volatile__(»··»···»···»···»···»···\
78 ".machine push; .machine \"power9\"; mffsl %0; .machine pop" »\
79 : "=f" (__u.__d));»···»···»···»···»···»···\
80 (fpu_control_t) (__u.__ll & _FPU_MASK_RC);»·»···»···»···\
81 })
