Reformatting is done with `black` (23.1.0). If you end up having problems merging this commit because you have made changes to a python file, the best way to handle that is to run `git checkout --ours <yourfile>` and then reformat it with black.

[lldb][test] TestCPP20Standard.py: make it a libc++ test 2023-05-02T11:38:53+00:00 Michael Buch michaelbuch12@gmail.com 2023-05-01T17:09:54+00:00 52882de0e641487329c9e093a90ea3dad01842c8 We just want to test whether the language switch works. This is easier to control for libc++, since for bots building the tests against libstdc++ we might not have the necessary `<compare>` header available currently.

[lldb] Allow evaluating expressions in C++20 mode 2023-04-14T16:10:18+00:00 Michael Buch michaelbuch12@gmail.com 2023-04-14T16:01:49+00:00 89cd0e8c267f57004a734c94ff15c6bd0facf646 This patch allows users to evaluate expressions using `expr -l c++20`. Currently DWARF keeps the CU's at `DW_AT_language` at `DW_LANG_C_plus_plus_14` even when compiling with `-std=c++20`. So even in "C++20 programs" expression evaluation will by default be performed in `C++11` mode for now. Enabling `C++14` has been previously attempted at https://reviews.llvm.org/D80308 There are some remaining issues around evaluating C++20 expressions. Mainly, lack of support for C++20 AST nodes in `clang::ASTImporter`. But these can be addressed in follow-up patches.
