Hi Richard
I just found that modifying match.pd may be a better way since for
forwprop-19.c, VEC_PERM_EXPR exists in all gimple until 235t.optimize with
current trunk code, that leave us no pass to ‘scan-tree-dump-not’.

It’s probably because loongarch64 doesn’t support

Hi Richard
Thank your for your detailed explanation, I’ll patch the test case with
suggestions form LuLu.

I’m not sure whether if loongarch will support it or should I just
limit the test target for p

I'm not sure i
Hi RuoYao
It’s probably because loongarch64 doesn’t support
can_vec_perm_const_p(result_mode, op_mode, sel2, false)
I’m not sure whether if loongarch will support it or should I just limit the
test target for pr54346.c?

Hi Richard
Sure, I’ll also check the VLA case once I’m back from vacation, thank you for
your help.

This patch implemented the optimization in PR 54346, which Merges
c = VEC_PERM_EXPR ;
d = VEC_PERM_EXPR ;

d = VEC_PERM_EXPR ;
