[PATCH 0/3] Add Power10 IEEE 128-bit min, max, conditional move

This is a revision of the patches I sent on May 18th. I tested it on 3 platforms: * Power9 little endian, --with-code=power9; * Power8 big endian, --with-code=power8, both 32/64-bit tests done; * Power10 little endian, --with-code=power10. All systems bootstrapped and there wer

[PATCH 1/3] Add IEEE 128-bit min/max support on PowerPC.

[PATCH 1/3] Add IEEE 128-bit min/max support on PowerPC. This patch adds the support for the IEEE 128-bit floating point C minimum and maximum instructions. The next patch will add the support for using the compare and set mask instruction to implement conditional moves. This patch does not try

[PATCH 2/3] Fix IEEE 128-bit min/max test.

[PATCH 2/3] Fix IEEE 128-bit min/max test. This patch fixes the float128-minmax.c test so that it can accommodate the generation of xsmincqp and xsmaxcqp instructions on power10. I changed the effective target from 'float128' to 'ppc_float128_hw', since this needs the IEEE 128-bit float hardware

[PATCH 3/3] Add IEEE 128-bit fp conditional move on PowerPC.

[PATCH 3/3] Add IEEE 128-bit fp conditional move on PowerPC. This patch adds the support for power10 IEEE 128-bit floating point conditional move and for automatically generating min/max. In this patch, I simplified things compared to previous patches. Instead of allowing any four of the modes t

[PATCH] c++: Failure to delay noexcept parsing with ptr-operator [PR100752]

We weren't passing 'flags' to the recursive call to cp_parser_declarator in the ptr-operator case and as an effect, delayed parsing of noexcept didn't work as advertised. The following change passes more than just CP_PARSER_FLAGS_DELAY_NOEXCEPT but that doesn't seem to break anything. I'm not pas

[pushed] c++: remove redundant warning [PR100879]

Before my r277864, build_new_op promoted enums to int before passing them on to cp_build_binary_op; after that commit, it doesn't, so warn_for_sign_compare sees the enum operands and gives a redundant warning. This warning dates back to 1995, and seems to have been dead code for a long time--likely

[PATCH] Use range based loops to iterate over vec<> in various places

[PATCH] Improvements to fur_source interface class, enhanced stmt folding options.

I recently introduced the fur_source class as an intermediary between the Fold_Using_Ranges (FUR) class and where to pick up any ssa_names that it needs.    The initial idea was to abstract out a set of frequently changing parameters so the client fold routines wouldn't have to change every tim

[PATCH 1/2] Fix PR 100925: Limit some a?CST1:CST2 optimizations to intergal types only

From: Andrew Pinski The problem here is with offset (and pointer) types is we produce a negative expression when this optimization hits. It is easier to disable this optimization for all non-integeral types instead of finding an integer type which is the same precission as the type to do the nega

[PATCH 2/2] Disallow pointer and offset types on some gimple

From: Andrew Pinski While debugging PR 100925, I found that the gimple verifiers don't reject NEGATE on pointer or offset type. This patch adds the check on some unary and binary gimple which should not have operated on pointer/offset types. OK? Bootstrapped and tested on x86_64-linux-gnu with n
