But that's only true for unsigned vals. For signed

Fine with me if x86 maintainers do not disagree

Hi,
IIUC, the function vectorizable_bb_reduc_epilogue missed to
consider the cost to extract the final value from the vector
for reduc operations. This patch is to add one time of
vec_to_scalar cost for extracting.
Bootstrapped & regtested on powerpc64le-linux-gnu P9.
The testing on x86_64 and a
Hi:
Here's updated patch which does 3 things:
1. Support vpermw/vpermb in ix86_expand_vec_one_operand_perm_avx512.
2. Support 256/128-bits vpermi2b in ix86_expand_vec_perm_vpermt2.
3. Add define_insn_and_split to optimize specific vector permutation to
opmov{dw,wb,qd}.
Bootstrapped and regtes

The patch extends the analyser’s functionality to understand and analyze
indirect calls (calls via a function pointer or calls to virtual functions )
On successful merging, the patch should also fix the following bugs :-
1. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100546
2. https://gcc.gnu
