Then why is every other type supported, but not 64? It makes no sense.

Actually, seems this is only a documentation bug. vec_mul for the int vectors
is not listed on any of the "PowerPC AltiVec/VSX Built-in Functions" pages,
even though it works. It emulates the multiplication o

clang 7.0.0 outputs the expected values, aka the gcc -O0 ones, at all
optimization levels. (it calls the builtin __builtin_altivec_crypto_vpmsumd,
but no other changes)

--- Comment #7 from Lauri Kasanen ---
Thanks for working on this. Per my experience, this is fast for gcc ;)
Are you sure about the smaller ones? To me they should not care about 64-bit
swaps, but clang lists them all as lane-sensitive:

--- Comment #9 from Lauri Kasanen ---
Can -mno-optimize-swaps be used per-function, in the code via some pragma?
Alternatively, does calling the instruction via inline asm prevent the
swapping?
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91275
--- Comment #14 from Lauri Kasanen ---
Inline asm works on the buggy versions. Thanks.

When using gcc 5.2 as the host compiler, there is no crash.
The gcc docs state that any version of gcc above 3.4 is supported, so this is
still a bug.
