[PATCH v5 5/5] c++modules: report module mapper files as a dependency

It affects the build, and if used as a static file, can reliably be tracked using the `-MF` mechanism. gcc/cp/: * mapper-client.cc, mapper-client.h (open_module_client): Accept dependency tracking and track module mapper files as dependencies. * module.cc (make_map

[PATCH v5 3/5] p1689r5: initial support

This patch implements support for [P1689R5][] to communicate to a build system the C++20 module dependencies to build systems so that they may build `.gcm` files in the proper order. Support is communicated through the following three new flags: - `-fdeps-format=` specifies the format for the out

[PATCH v5 1/5] libcpp: reject codepoints above 0x10FFFF

Unicode does not support such values because they are unrepresentable in UTF-16. libcpp/ * charset.cc: Reject encodings of codepoints above 0x10. UTF-16 does not support such codepoints and therefore all Unicode rejects such values. Signed-off-by: Ben Boeckel --- li

[PATCH v5 2/5] libcpp: add a function to determine UTF-8 validity of a C string

This simplifies the interface for other UTF-8 validity detections when a simple "yes" or "no" answer is sufficient. libcpp/ * charset.cc: Add `_cpp_valid_utf8_str` which determines whether a C string is valid UTF-8 or not. * internal.h: Add prototype for `_cpp_valid_utf8_s

[PATCH v5 0/5] P1689R5 support

Hi, This patch series adds initial support for ISO C++'s [P1689R5][], a format for describing C++ module requirements and provisions based on the source code. This is required because compiling C++ with modules is not embarrassingly parallel and need to be ordered to ensure that `import some_modul
