[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] Support _IONBF buffering for read_unlocked (#120677)

2025-01-09T03:24:16+00:00

Support _IONBF buffering for read_unlocked. Add the functions
read_unlocked_nbf() and read_unlocked_fbf().

Fixes: #120155

[libc] Add proxy headers to handle memory allocation associated with the header `#include (#114690)

2024-11-03T19:28:24+00:00

This finishes the work from
https://github.com/llvm/llvm-project/pull/114453 by adding proxy headers
for `malloc`, `realloc`, `free` and `aligned_alloc`.

[libc] Enable most of the libc entrypoitns for riscv (#99771)

2024-07-20T18:47:09+00:00

This patch enables most of the libc entrypoints for riscv, except for fstatvfs, statvfs, dmull and fmull which are currently failing compilation. float16 is also not added, as rv32 doesn't seem to support it yet.

This patch also fixes the call to seek, which should take an off_t, and was missed in PR #68269.

Reland: [libc] Move off_t and stdio macros to proxy hdrs (#98384)

2024-07-11T18:09:51+00:00

reland of https://github.com/llvm/llvm-project/pull/98215

Additionally adds proxy headers for FILE and the fopencookie types

The arm32 build has been failing due to redefinitions of the off_t type.
This patch fixes this by moving off_t to a proper proxy header. To do
this, it also moves stdio macros to a proxy header to hopefully avoid
including this proxy header alongside this public stdio.h.
