I added _mm512_reduce_round_pd() and bunch of other missing intrinsic last
year.

--- Comment #2 from Jakub Jelinek  ---
I must say I don't understand the #c1 comment, GCC
__builtin_ia32_reducepd512_mask etc. don't take the rounding mode argument at
all.  And not only the _mm_*reduce_round* intrinsics are missing,
_mm512_*reduce_round* is missing too.

--- Comment #1 from MCCCS  ---
Only the `_mm_` reduce-intrinsics don't exist. You can still call them from GCC
by

1) Opening the table
https://github.com/llvm-mirror/clang/blob/master/lib/Headers/avx512dqintrin.h

2) Ctrl + F for the function (e.g. _mm512_reduce_round_pd)

3) Call the function in the definition (e.g. __builtin_ia32_reducepd512_mask)

But this is only a workaround, those `_mm_` functions/macros should be added, I
agree.
