Re: [24/32] module mapper

I've noticed the following issues with the module mapper in the -fdirectives-only mode: 1. When partially preprocessing the module interface unit, the mapper receives the MODULE-EXPORT request that's unnecessary (BMI is not written): g++ ... -x c++ -E -fdirectives-only -o hello.gcm.ii h

[PATCH] Add a new pattern in 4-insn combine

Hi, This patch adds a new pattern in 4-insn combine. It supports the following sign_extend(op: zero_extend, zero_extend) optimization. In the patch, newpat is split twice. The first split becomes newi1pat and the second becomes newi2pat. They replace i1, i2 and i3 if all of them can be recogn

This leads to code size, compile time and compile time memory use regressions sompared to earlier versions where we merged more aggressively bec

[PATCH] 2/2 Remove debug/array

Following a recent fix on std::array this test started to fail in _GLIBCXX_DEBUG mode. FAIL: 23_containers/array/comparison_operators/96851.cc (test for excess errors) Rather than fixing it and now that __glibcxx_assert is constexpr compatible I would like to propose to simply remove __gnu_d

[PATCH] 1/2 Make _GLIBCXX_DEBUG checks constexpr compatible

Now that __glibcxx_assert is constexpr compatible we can do the same for the _GLIBCXX_DEBUG equivalent. I had also try to do the same on my own so this patch contains the string_view tests I had written when doing so. I plan to activate some _GLIBCXX_DEBUG checks when _GLIBCXX_ASSERTIONS is
