[libc] Migrate to using LIBC_NAMESPACE_DECL for namespace declaration (#98075)

2024-07-11T19:35:22+00:00

This is a part of #97655.

[libc] Move the internal extern "C" symbols inside the namespace (#98232)

2024-07-09T23:22:19+00:00

This ensures that these symbols inherit the namespace visibility.

[libc] added quick_exit function (#93620)

2024-05-31T17:19:10+00:00

- In /libc/src/__support/ OSUtil, changed quick_exit to just exit, and
put in namespace
LIBC_NAMESPACE::internal.
- In /libc/src/stdlib added quick_exit
- Added test files for quick_exit

[libc][OSUtil] refactor quick_exit to be an object library everywhere (#85955)

2024-03-26T15:27:43+00:00

The usage of __builtin_unreachable after calls to quick_exit were distressing.
If a function is properly marked [[noreturn]] then __builtin_unreachable is not
necessary.

Looking into this further, we seem to have header only implementations for CPU
targets. The inline nature of these functions is curious; we're going to exit,
it doesn't matter if we need to pay the call of a function or not. If we just
make these functions have distinct TUs rather than be header only, we can clean
up the cmake rules for quick_exit which were different between CPU and GPU.

Remove darwin support for quick_exit. This isn't being tested, and we can bring
it back when necessary.

[libc][stdlib] initial support for __cxa_finalize (#85865)

2024-03-22T15:28:03+00:00

I'm trying to break up the pieces of supporting __cxa_finalize into smaller
commits. Provide this symbol first, and make use of it from exit.

Next will be to store __dso_handle, then finally to only run callbacks that
were registered from a specific dso.

[libc] Mass replace enclosing namespace (#67032)

[libc] Silence warning about returning from noreturn function

2023-06-07T11:23:00+00:00

The `exit` entrypoint calls into `quick_exit` which is marked noreturn
in some cases. This will cause errors because we then have control flow
externally. This warning can be silenced by using a
`__builtin_unreachable` instruction accordingly.

[libc] Implement `exit` for the GPU partially

2023-04-28T01:32:00+00:00

This patch implements the `exit` function on the GPU. This required
breaking the entrypoints calling eachother on `linux` since this doesn't
work with a non-aliased target. This is only partial support because
full support requires a malloc / free implementation for the exit
callbacks array.
