Like convert we can sink view_convert into vec_cond but
we can only do it if the element types are nop_conversions.
This is to allow conversion between signed and unsigned types only.
Rather than between integer and float types which mess up the vec_cond
so that isel does not understand `a?-1:0`

This patch refactors the Phase 3 (Demand fusion) and rename it into Earliest
fusion.
I do the refactor for the following reasons:
1. Current implementation of phase 3 is doing too many things which makes the
code quality
quite messy and not easy to maintain.
2. The demand fusion I do
Jeff,
Thanks a lot for your comments.
The widen shift mode is on i1/i2 before they're combined with i3 to newpat.
The newpat matches rotate/mask pattern. The i1/i2 itself don't match
rotate/mask pattern.
I did an experiment to disable widen shift mode for
lshiftrt. I tested it on

We can't, avx10.1 is taken as an indivisible ISA which contains all

I am so sorry sending the wrong and duplicate patch.
Forget about this patch.
This patch exports 'compute_antinout_edge' and 'compute_earliest' as global
scope
which is going to be used in VSETVL PASS of RISC-V backend.
The demand fusion is the fusion of VSETVL information to emit VSETVL which
dominate and pre-config for most
of the RVV instructions in order to elide

Hi,
testsuite/libgomp.c/simd-math-1.c calls nonstandard functions that are not
available on darwin (and possibly other systems?). Because I did not want to
disable their testing completely, I suggest we simply use preprocessor macros
to avoid them on darwin.
This fixes the test failure on

Makes sense. I’ve committed, as well as another one, attached, slightly
amending the expected pattern of a sarif plugin test.

Partial vector src is forced to a register as ops[1], we can use it
instead of SRC in the call to ix86_expand_sse_cmp. This change avoids
forcing operand[1] to a register in sign/zero-extend expanders.

Hi,
The fact that this test needs alias support was indicated in
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85656 but never committed. Without
it, the test fails on darwin.
OK to commit?
