[PATCH] PowerPC address support clean, patch 2 of 4

whether a particular reload register class supports a particular D*-form instruction. This is patch #2 of 4 and it moves some of the mode support functions to be next to each other in the source. I have done a bootstrap with patches 1-4 and did a make check comparison on a little endian power8 system

[PATCH] Introduce can_remove_lhs_p

As promised in , this is a simple clean-up which makes use of a new predicate. Richi suggested adding maybe_drop_lhs_from_noreturn_call which would be nicer, but I didn't know how to do that, given the handling if lhs is an SSA_NAME. Boots

[PATCH] Improve *avx_vperm_broadcast_*

Hi! The vbroadcastss and vpermilps insns are already in AVX512F & AVX512VL, so can be used with v instead of x, the splitter case where we for AVX emit vpermilps plus vpermf128 is more problematic, because the latter insn isn't available in EVEX. But, we can get the same effect with vshuff32x4 wh

[PATCH] Improve avx_vec_concat

Hi! Not sure how to easily test these. In any case, for the vinsert* case, we don't have vinserti128 nor vinsertf128 in evex, so need to use vinsert[if]{64x4,32x4} or for DQ {64x2,32x8}. For the case with zero in the other half, we need AVX512VL and it isn't guaranteed for the output operand, bec

[PATCH] Fix PR71254

I am currently testing the following patch that makes the control dependences data structures survive edge redirection when the pass knows it doesn't alter control dependences. It basically replaces the edge list with a vector of BB indices (so even removing BBs and still querying the co
