Here's the patch I'm going to check in.
The patch will regress pr91838.C with extra options: -march=cascadelake
using T = unsigned char; // or ushort, or uint
using V [[gnu::vector_size(8)]] = T;
V f(V x) { return x >> 8 * sizeof(T); }
Basically, the testcase is UB with logic right shift more th
Hi:
This patch is about to add expanders for vashl,
vlshr,
vashr and vashr.
Besides there's some assumption in expand_mult_const that mul and
add must be available at the same time, but for i386, addv8qi is
restricted under TARGET_64BIT, but mulv8qi not, that could cause ICE.
So restrict mulv8qi
