IIUC, this can also help PR target/93123. Add it to the PR marker too if so. This patch aligns with what the other ports do, I think it's good, but note that it can regress some case like: ``` vector unsigned __int128 test(unsigned __int128 *a, unsigned __int128 *b, unsigned __int128 *c, unsigned __int128 *d) { unsigned __int128 t1 = *a | *b; unsigned __int128 t2 = *c & *d; unsigned __int128 t3 = t1 ^ t2; return (vector unsigned __int128)t3; } ``` w/o the proposed patch: lxv 32,0(5) lxv 0,0(6) lxv 45,0(3) lxv 33,0(4) xxland 32,32,0 vor 2,1,13 vxor 2,2,0 vs. w/ this patch: ld 9,8(6) ld 8,0(5) ld 10,8(5) ld 0,0(6) ld 11,0(3) ld 6,8(3) ld 5,0(4) ld 7,8(4) and 8,8,0 and 10,10,9 or 9,5,11 xor 9,9,8 or 8,7,6 xor 8,8,10 mtvsrdd 34,8,9 It can get the optimal insn seq before, but fails to with the proposed patch. Apparently we don't have some support to get back the operation in vector when it's beneficial for now. I guess the cases in PR100694 and PR93123 are dominated and the regressed case is corner. So we can probably install this patch first and open a bug for further enhancement. Segher, what do you think of this?
