RFA: vectorizer patches 1/2 : WIDEN_MULT_PLUS support

Our target (eSi-RISC) doesn't have DOT_PROD_EXPR or WIDEN_SUM_EXPR operations in the standard vector modes; however, it has a vectorized WIDEN_MULT_PLUS_EXPR implementation with a double-vector output, which works just as well, with a little help from the compiler - as implemented in these patc

[doc, committed] add index entries for positive forms of -fno-xxx and -mno-xxx options

As noted in PR65703, there was previously a reference in the manual to -fdefer-pop but if you searched for the documentation of that option, you wouldn't find it unless you thought to look for -fno-defer-pop instead. This was a general problem affecting many -fno-xxx and -mno-xxx options. I'v

[PATCH] Fix ICE with -fopt-info-inline (PR ipa/87955)

PR ipa/87955 reports a problem I introduced in r265920, where I converted the guard in report_inline_failed_reason from using: if (dump_file) to using if (dump_enabled_p ()). without updating the calls to cl_target_option_print_diff and cl_optimization_print_diff, which assume that dump_file is

[PATCH] combine: More make_more_copies

This makes make_more_copies do what its documentation says, that is, only make an intermediate pseudo if copying to a pseudo. This regressed generated code quality when we didn't keep the original notes that were on the copy, but since r265582 we do, and only allowing pseudos now is a win. It als

Fix hashtable node deallocation

While working on a hashtable enhancement I noticed that we are not using the correct method to deallocate node if the constructor throws in _ReuseOrAllocNode operator(). I had to introduce a new _M_deallocate_node_ptr for that as node value shall not be destroy again. I also check other places

Re: [PATCH] Integration of parallel standard algorithms for c++17

This patch has been held up by licensing issues, specifically, awaiting upstream's plans to relicense the code from Apache 2.0 to the libc++ license - https://llvm.org/docs/DeveloperPolicy.html#license We expect the relicensing to conclude within the next few weeks. At that time I will be resub

Re: [PATCH, libgfortran] Remove recursion check

Hi Janne, 1) It's KISS 2) I can't find anything in the code that would lead to endless recursive invocation of the error printing functions. So, Ok for trunk? With async I/O, I think the possibilities of hitting concurrent errors have increased, so I'd still prefer the solution with wrappi

[RFC][PATCH, rs6000] Replace X-form addressing with D-form addressing in new pass for Power9

New D-form instructions available on Power9 introduce new code generation options that result in more efficient execution. This new pass scans existing rtl expressions and replaces them with rtl expressions that favor selection of the D-form instructions in contexts for which the D-form instr

[PATCH 3/3] OpenACC 2.6 manual deep copy support (attach/detach)

This patch implements the bulk of support for OpenACC 2.6 manual deep copy for the C, C++ and Fortran front-ends, the middle end and the libgomp runtime. I've incorporated parts of the patches previously posted by Cesar: https://gcc.gnu.org/ml/gcc-patches/2018-10/msg01941.html https://gcc.gnu.or

[PATCH 1/3] Host-to-device transfer coalescing & magic offset value self-documentation

[PATCH 0/3] OpenACC 2.6 manual deep copy support (attach/detach)

Hi, This patch series adds support for OpenACC 2.6's "manual deep copy" feature. This consists of three main parts: * Variable lists in data clauses can specify members of structs (in C/C++) or derived types (in Fortran). In C/C++ we allow either "." or "->" to be used to select members
