--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
So I can reproduce it with GCC 7.3.0 with:
```
-xc -march=skylake -mmmx -mno-3dnow -msse -msse2 -msse3 -mssse3 -mno-sse4a
-mcx16 -msahf -mmovbe -maes -mno-sha -mpclmul -mpopcnt -mabm -mno-lwp -mfma
-mno-fma4 -mno-xop -mbmi -msgx -mbmi2 -mno-tbm -mavx -mavx2 -msse4.2 -msse4.1
-mlzcnt -mrtm -mhle -mrdrnd -mf16c -mfsgsbase -mrdseed -mprfchw -madx -mfxsr
-mxsave -mxsaveopt -mno-avx512f -mno-avx512er -mno-avx512cd -mno-avx512pf
-mno-prefetchwt1 -mclflushopt -mxsavec -mxsaves -mno-avx512dq -mno-avx512bw
-mno-avx512vl -mno-avx512ifma -mno-avx512vbmi -mno-avx5124fmaps
-mno-avx5124vnniw -mno-clwb -mno-mwaitx -mno-clzero -mno-pku -mno-rdpid -m32
-O2 -std=gnu11 -fgnu89-inline -fmerge-all-constants -fno-strict-aliasing
-frounding-math -fstack-protector-all -mpreferred-stack-boundary=4 -fPIC
```
But it passes with GCC 7.4.0.
