Consider this following case:
void
foo (int8_t *in, int8_t *out, int8_t x)
{
for (int i = 0; i < 16; i++)
in[i] = x;
}
Compile option: --param=riscv-autovec-preference=scalable -fno-builtin
Before this patch:
foo:
li a5,16
csrra4,vlenb
vsetvli a3,zero,e8,m1
This is a new version of the patch.
Instead of doing the matching of inversion comparison directly inside
match, creating a new function (bitwise_not_equal_p) to do it.
It is very similar to bitwise_equal_p that was added in
r14-2751-g2a3556376c69a1fb
but instead it says `expr1 == ~expr2`. A follo
This patch reattempts to change the ZERO_EXTRACTs and SIGN_EXTRACTs
in i386.md to consistently use QImode for bit offsets (i.e. third and fourth
operands), matching the use of QImode for bit counts in shifts and rotates.
This iteration corrects the "ne:QI" vs "eq:QI" mistake in the previous

This patch recognizes Zicond patterns when the select pattern
with condition eq or neq to 0 (using eq as an example), namely:
1 rd = (rs2 == 0) ? non-imm : 0
2 rd = (rs2 == 0) ? non-imm : non-imm
3 rd = (rs2 == 0) ? reg : non-imm
4 rd = (rs2 == 0) ? reg : reg
