[clang] Mark `__builtin_convertvector` and `__builtin_shufflevector` as `constexpr`. (#112129)

2024-10-14T16:09:36+00:00

Closes #107985.

LanguageExtensions.rst states that `__builtin_shufflevector` and
`__builtin_convertvector` can be evaluated as constants, but this is not
reflected in Butiltins.td. This patch aligns these two.

Clang: Support minimumnum and maximumnum intrinsics (#96281)

2024-10-14T07:49:01+00:00

We just introduce llvm.minimumnum and llvm.maximumnum intrinsics support
to llvm. Let's support them in Clang.

See: #93033

[Clang] Improve type traits recognition in `__has_builtin` (#111516)

2024-10-08T21:03:32+00:00

`__has_builtin` was relying on reversible identifiers and string
matching to recognize builtin-type traits, leading to some newer type
traits not being recognized.

Fixes #111477

[Clang][clang-cl] Implement `__builtin_FUNCSIG`

2023-05-19T16:02:44+00:00

This patch implements __builtin_FUNCSIG intrinsic which returns the same string as __FUNCSIG__.

Add __builtin_FILE_NAME()

2023-03-17T13:52:41+00:00

Add '__builtin_FILE_NAME()', which expands to the filename because the
full path is not always needed. It corresponds to the '__FILE_NAME__'
predefined macro and is consistent with the other '__builin' functions
added for predefined macros.

[Clang] Add __has_constexpr_builtin support

2022-10-21T11:23:10+00:00

The `__has_constexpr_builtin` macro can be used to check
whether the builtin in constant-evaluated by Clang frontend.

Accept __is_same_as as a GCC-compatibility synonym for the proper trait name __is_same.

Add __has_builtin support for builtin function-like type traits.

2019-08-14T02:30:11+00:00

Summary:
Previously __has_builtin(__builtin_*) would return false for
__builtin_*s that we modeled as keywords rather than as functions
(because they take type arguments). With this patch, all builtins
that are called with function-call-like syntax return true from
__has_builtin (covering __builtin_* and also the __is_* and __has_* type
traits and the handful of similar builtins without such a prefix).

Update the documentation on __has_builtin and on type traits to match.
While doing this I noticed the type trait documentation was out of date
and incomplete; that's fixed here too.
