[PATCH][AArch64] Define WORD_REGISTER_OPERATIONS to zero and comment why

Hi all, WORD_REGISTER_OPERATIONS is currently cryptically commented out in aarch64.h. In reality, we cannot define it to 1 for aarch64 because operations narrower than word_mode (DImode for aarch64) don't behave like word_mode if they use the W-form of the registers. They'll be performed in SIm

[PATCH][AArch64] Simplify ashl3 expander for SHORT modes

Hi all, The ashl3 expander for QI and HI modes is needlessly obfuscated. The 2nd operand predicate accepts nonmemory_operand but the expand code FAILs if it's not a CONST_INT. We can just demand a const_int_operand in the predicate and remove the extra CONST_INT check. Looking at git blame, it s

[PATCH][AArch64] Delete obsolete CC_ZESWP and CC_SESWP CC modes

Hi all, The CC_ZESWP and CC_SESWP are not used anywhere and seem to be a remmant of some old code that was removed. The various compare+extend patterns in aarch64.md don't use these modes. So it should be safe to remove them to avoid future confusion. Bootstrapped and tested on aarch64. Ok for

[PATCH][ARM] Fix costing of sign-extending load in rtx costs

Hi all, Another costs issue that came out of the investigation for PR 65932 is that sign-extending loads get a higher cost than they should in the arm backend. The problem is that when handling a sign-extend of a MEM we add the cost of the load_sign_extend cost field and then recursively add the
