] RISC-V: Support vmfxx.vf for autovec comparison of
vec and imm
Yes. I think we are lacking some combine patterns to do all vector-scalar
combinations.
If you are interested at this topic, you can do some investigations on that (I
believe currently no body works on it for now).
I bet we should

Hi,
I applied the mentioned last_combine
patch(https://patchwork.ozlabs.org/project/gcc/patch/mptbka7em9w@arm.com/).
And did some initial tests.
Found that:
1. Float vector-scalar and vector-imm are OK
2. Integer vector-scalar is OK
3. Integer vector-imm(e.g. a[i] > 16) is
Hi juzhe,
Yes, for comparison between vector and scalar variable, this patch is not work,
because the scalar is duplicated in loop vectorize pass.
I have not found idea for this situation, so solve vector-imm comparison first.
Thanks for remind this, I will try that patch.
Thanks.
