Hi,
Thank you for your review & help.
I could not fetch the merged patch from gcc master of git.
Is there any problem for this ?
Thanks.

Some target like RISC-V allow to group vector register as a whole,
and only operate part of it in fact, but the 'init-regs' pass will add
initialization
for uninitialized registers. Add this hook to reject this action for reducing
instruction.

Insn seqs before sched:
.L1:
a5 = insn-1 (a0)
a6 = insn-2 (a1)
a7 = insn-3 (a7, a5)
a8 = insn-4 (a8, a6)
Jmp .L1
Insn-3 & insn-4 is REG_DEP_TRUE of insn-1 & insn-2,
so insn-3 & insn-4 will be as the last of ready list.
And this patch will put 0 cost dependency due to a bypass
as highest numbered

Hi,
The size of generated file like insn-emit.c is very huge
if we add lots of define_expand patten or define_insn patten.
It’s present easily when there are much more intrinsic interfaces
it costs much more time to create toolchain with compiling these files
:(
