--- Comment #10 from Peter Bergner ---
A similar error happens with the __builtin_vsx_udiv_2di() that happens with
__builtin_vsx_div_2di(), which shows the splitter for vsx_udiv_v2di calling
gen_udivdi3() directly:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83926
--- Comment #9 from Peter Bergner ---
So the problem is that the splitter for vsx_div_v2di unconditionally calls
gen_divdi3() , which assumes we have a 64-bit integer HW div insn. If you do a
scalar 64-bit div, we notice we don't have that HW

--- Comment #7 from Segher Boessenkool ---
It is first V2DI in the RTL, which exists just fine (but there is no
such divide insn); then when it is split to two DImode divides, it
just generates div:DI etc., which does not exist for -m32.
So we

But I assume that's your transcription error. In the test case the arguments
are vector long long.

--- Comment #5 from Bill Schmidt ---
That looks completely invalid, the args should be vector long long, not long
long.

--- Comment #4 from Will Schmidt ---
I'm having a moment of doubt on the validity of the testcases involved here.
vector long long a = vec_div(long long b, long long c);
Any chance that is invalid for -m32 ? I don't see a whole lot of

looks like No, this also fails on the gcc 7

Does this work on GCC 7 (obviously without -mno-fold-gimple)? If so, please
mark as [8 regression] in title.
