Fangrui Song	83ea47acd7	[test] Make tests pass regardless of gnu++14/gnu++17 default ... GCC from 11 onwards defaults to -std=gnu++17 for C++ source files. We want to do the same (https://discourse.llvm.org/t/c-objc-switch-to-gnu-17-as-the-default-dialect/64360). Split RUN lines, adjust `-verify`, or add `__cplusplus < 201703L` or `-Wno-dynamic-exception-spec`, so that tests will pass regardless of gnu++14/gnu++17 default. We have a desire to mark a test compatible with multiple language standards. There are ongoing discussions how to add markers in the long term: * https://discourse.llvm.org/t/iterating-lit-run-lines/62596 * https://discourse.llvm.org/t/lit-run-a-run-line-multiple-times-with-different-replacements/64932 As a workaround in the short term, add lit substitutions `%std_cxx98-`, `%std_cxx11-14`, etc. They can be used for tests which work across multiple language standards. If a range has `n` standards, run lit multiple times, with `LIT_CLANG_STD_GROUP=0`, `LIT_CLANG_STD_GROUP=1`, etc to cover all `n` standards.

Adam Czachorowski	08128fe705	[clang] Make member var invalid when static initializer is invalid. ... Previously we would show an error, but keep the member, and also the CXXRrecordDecl, valid. This could lead to crashes when attempting to access the record layout or size. Differential Revision: https://reviews.llvm.org/D105478	2021-08-03 11:52:52 +02:00
