[PATCH] c++: Change the default dialect to C++17.

Since GCC 9, C++17 support is no longer experimental. It was too late to change the default C++ dialect to C++17 in GCC 10, but I think now it's time to pull the trigger (C++14 was made the default in GCC 6.1). We're still missing two C++17 library features, but that shouldn't stop us. See

[PATCH] c++: Regenerate cp/cfns.h.

Current cfns.h includes register-qualified variables and that wouldn't play well when bootstrapping with GCC that uses the C++17 dialect, because 'register' was removed in C++17. Regenerating it using the command specified in cfns.h luckily cleaned this up. Bootstrapped/regtested on x86_64-pc-lin

[PATCH] c++: Implement DR 1512, Pointer comparison vs qual convs [PR87699]

This patch resolves DR 1512 (and, by turn, DR 583). This entails: 1) Relational pointer comparisons against null pointer constants have been made ill-formed: void f(char *p) { if (p > 0) // ... } was always invalid in C but was -- accidentally -- allowed in C++. 2) Th

[PATCH] c++: Don't add built-in operator for ++ on bool.

This feels extremely obscure but at least it's an opportunity to fix the comments. P0002R1 removed deprecated operator++(bool) in C++17 so let's avoid adding a builtin overload candidate for ++ when the type is bool. Bootstrapped/regtested on x86_64-pc-linux-gnu, ok for trunk? * call.c (

[committed][GCC9] d: Fix wrong vtable offset in virtual function call

Hi, This patch fixes PR95155, which prevented the D front-end in gcc-9 from being able to bootstrap a self-hosted D compiler. The Semantic (pass 1) analysis for classes is handled by ClassDeclaration::semantic. For a given class, this method may be ran multiple times in order to resolve forward

[committed][GCC9] libphobos: Fix struct layout of stat_t on sparc-*-solaris*

Hi, The last change to the bindings removed the st_pad3 field from the wrong struct. It should have been stat64_t that needed updating instead. Patch backported from r10-8066, committed to gcc-9 branch. Iain. --- libphobos/ChangeLog PR d/90719 * libdruntime/core/sys/posix/sys/
