[clang][Interp] consider "MS constexpr" functions as well 2024-02-06T20:49:13+00:00 Timm Bäder tbaeder@redhat.com 2024-02-06T19:15:56+00:00 3f1e95a9d4cc1fdb933390247d0bd4391cf93f60 This implements the minimum amout of support for this feature to get the test/AST/ms-constexpr.cpp test working. More has to be added to get SemaCXX tests to work.

[clang-cl] Add support for [[msvc::constexpr]] C++11 attribute (#71300) 2023-12-09T10:35:38+00:00 Richard Dzenis dzenis@richard.lv 2023-12-09T10:35:38+00:00 b3e6ff331925dde24a4707452d657da0fdf7f588 This commit introduces support for the MSVC-specific C++11-style attribute `[[msvc::constexpr]]`, which was introduced in MSVC 14.33. The semantics of this attribute are enabled only under MSVC compatibility (`-fms-compatibility-version`) 14.33 and higher. Additionally, the default value of `_MSC_VER` has been raised to 1433. The current implementation lacks support for: - `[[msvc::constexpr]]` constructors (see #72149); at the time of this implementation, such support would have required an unreasonable number of changes in Clang. - `[[msvc::constexpr]] return ::new` (constexpr placement new) from non-std namespaces (see #74924). Relevant to: #57696 
This commit introduces support for the MSVC-specific C++11-style
attribute `[[msvc::constexpr]]`, which was introduced in MSVC 14.33.
The semantics of this attribute are enabled only under
MSVC compatibility (`-fms-compatibility-version`) 14.33 and higher.
Additionally, the default value of `_MSC_VER` has been raised to 1433.

The current implementation lacks support for:
- `[[msvc::constexpr]]` constructors (see #72149);
  at the time of this implementation, such support would have required
  an unreasonable number of changes in Clang.
- `[[msvc::constexpr]] return ::new` (constexpr placement new) from
  non-std namespaces (see #74924).
