[COMMITTED] RISC-V: Split VLS avl_type from NONVLMAX avl_type

[COMMITTED V4] RISC-V: Support combine cond extend and reduce sum to

This patch support combining cond extend and reduce_sum to cond widen reduce_sum

those RVV insn with length set to the number of units of VLS modes.

How often do we want to run these tests?
I was thinking of starting up a once-weekly run of compute-intensive

Add support for inline memmove expansions. The generated code is identical
as for memcpy, except that all loads are emitted before stores rather than
being interleaved. The maximum size is 256 bytes which requires at most 16
registers.

Hi, Patrick.
GNU rvv intrinsic api test-generator has been merged:
https://github.com/riscv-non-isa/rvv-intrinsic-doc/commits/main
Could you include the full RVV intrinsic API test in your test CI?
Currently, we don't include all API test in the GCC testsuite since it's too
big.
Also。 Remove math.h include。
Instead, plz use __builtin_ceil.

Yes, this was the method that came to mind at first, and I didn't send a

Now GCC middle-end can support undefined value which is traslated into

This patch is to enable RISC-V backend undefine value in ELSE value of
