[libc][math] Refactor expf implementation to header-only in src/__support/math folder. (#143790)

2025-06-12T17:18:30+00:00

This is a step in preparation for:

[libc] Move libc_errno.h to libc/src/__support and make LIBC_ERRNO_MODE_SYSTEM to be header-only. (#143187)

2025-06-11T20:25:27+00:00

This is the first step in preparation for:

[libc] Make RPC allocation size query constexpr

2025-03-26T14:21:43+00:00

Summary:
Let this be used for a static array.

[libc] Make RPC server handling header only (#131205)

2025-03-14T00:23:21+00:00

Summary:
This patch moves the RPC server handling to be a header only utility
stored in the `shared/` directory. This is intended to be shared within
LLVM for the loaders and `offload/` handling.

Generally, this makes it easier to share code without weird
cross-project binaries being plucked out of the build system. It also
allows us to soon move the loader interface out of the `libc` project so
that we don't need to bootstrap those and can build them in LLVM.

[libc][NFC] use `__has_builtin` instead of checking macros.

[libc] Make the RPC headers work when included from CUDA or HIP (#120016)

2024-12-16T15:09:03+00:00

Summary:
In order for this to work with CUDA we need to declare functions as
__host__ and __device__ while also making sure we only call the GPU
functions during the CUDA / HIP compile stage.

libc: Prefix RPC Status code to avoid conflict in windows build (#119991)

2024-12-15T14:35:44+00:00

Somehow conflict with define in wingdi.h.

Fix build failures:

[libc][NFC] Rename RPC opcodes to better reflect their usage

2024-12-02T21:35:08+00:00

Summary:
RPC_ is a generic prefix here, use LIBC_ to indicate that these are
opcodes used to implement the C library

[libc] Move libc server handlers to a shared header (#117908)

2024-11-27T20:57:52+00:00

Summary:
We can simply include this header from the shared directory now and do
not need to have this level of indirection. Simply stash it with the
other libc opcode handlers.

If we were able to move the printf handlers to the shared directory then
this could just be a header as well, which would HEAVILY simplify the
mess associated with building the RPC server first in the projects
build, then copying it to the runtimes build.

[libc][NFC] Move RPC opcodes to the 'shared/' directory as well
