[Coverage] Handle `CoroutineSuspendExpr` correctly (#88898)

2024-05-15T22:39:12+00:00

This avoids visiting `co_await` or `co_yield` operand 5 times (it is
repeated under transformed awaiter subexpression, and under
`await_ready`, `await_suspend`, and `await_resume` generated call
subexpressions).

[Coroutines] Remove -fcoroutines-ts

2023-02-23T06:40:58+00:00

Since we decided to remove the support for `-fcoroutines-ts` in
clang/llvm17 and the clang16/llvm16 is branched. So we're going to
remove the `-fcoroutines-ts` option.

[clang][NFC] Cleanup some coroutine tests

2022-05-16T12:15:12+00:00

I noticed these two tests emit a warning about a missing
unhandled_exception.  That's irrelevant to what is being tested, but
is unnecessary noise.

[Coroutines] [Frontend] Lookup in std namespace first

2021-11-04T03:53:47+00:00

Now in libcxx and clang, all the coroutine components are defined in
std::experimental namespace.
And now the coroutine TS is merged into C++20. So in the working draft
like N4892, we could find the coroutine components is defined in std
namespace instead of std::experimental namespace.
And the coroutine support in clang seems to be relatively stable. So I
think it may be suitable to move the coroutine component into the
experiment namespace now.

This patch would make clang lookup coroutine_traits in std namespace
first. For the compatibility consideration, clang would lookup in
std::experimental namespace if it can't find definitions in std
namespace. So the existing codes wouldn't be break after update
compiler.

And in case the compiler found std::coroutine_traits and
std::experimental::coroutine_traits at the same time, it would emit an
error for it.

The support for looking up std::experimental::coroutine_traits would be
removed in Clang16.

Revert "[Coroutines] [Clang] Look up coroutine component in std namespace first"

2021-09-03T20:01:09+00:00

This reverts commit 2fbd254aa46b, which broke the libc++ CI. I'm reverting
to get things stable again until we've figured out a way forward.

[Coroutines] [Clang] Look up coroutine component in std namespace first

2021-09-03T02:22:55+00:00

Summary: Now in libcxx and clang, all the coroutine components are
defined in std::experimental namespace.
And now the coroutine TS is merged into C++20. So in the working draft
like N4892, we could find the coroutine components is defined in std
namespace instead of std::experimental namespace.
And the coroutine support in clang seems to be relatively stable. So I
think it may be suitable to move the coroutine component into the
experiment namespace now.

But move the coroutine component into the std namespace may be an break
change. So I planned to split this change into two patch. One in clang
and other in libcxx.

This patch would make clang lookup coroutine_traits in std namespace
first. For the compatibility consideration, clang would lookup in
std::experimental namespace if it can't find definitions in std
namespace and emit a warning in this case. So the existing codes
wouldn't be break after update compiler.
