[libc] Templatize the scanf Reader interface (#131037)

2025-03-18T06:51:24+00:00

This allows specializing the implementation for different targets
without including unnecessary logic and is similar to #111559 which did
the same for printf Writer interface.

[libc] Clean up skipped and failing cmake (#115400)

2024-11-11T22:28:36+00:00

I normally run my cmake with LIBC_CMAKE_VERBOSE_LOGGING set to ON so I
can debug build issues more easily. One of the effects of this is I see
which tests/entrypoints are skipped on my machine. This patch fixes up
the tests and entrypoints that were skipped, but easily fixed. These
were:

libc.src.pthread.pthread_spin_destroy
libc.src.pthread.pthread_spin_init
libc.src.pthread.pthread_spin_lock
libc.src.pthread.pthread_spin_trylock
libc.src.pthread.pthread_spin_unlock
(entrypoints were just missing)

libc.src.wchar.btowc
(I forgot to finish it)

libc.test.src.sys.statvfs.linux.statvfs_test
libc.test.src.sys.statvfs.linux.fstatvfs_test
(Incorrect includes for rmdir, needed some cleanup)

libc.test.integration.src.unistd.execve_test
(wrong dep for errno)

libc.test.src.math.smoke.fmaf_test
(add_fp_unittest doesn't support flags)

libc.test.src.stdio.scanf_core.converter_test
(needed to be moved away from string_reader, further cleanup needed)

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.

[libc] Mass replace enclosing namespace (#67032)

2023-09-26T09:45:04+00:00

This is step 4 of

[libc] Refactor scanf reader to match printf (#66023)

2023-09-22T19:50:02+00:00

In a previous patch, the printf writer was rewritten to use a single
writer class with a buffer and a callback hook. This patch refactors
scanf's reader to match conceptually.

[libc] add scanf entrypoints

2022-11-17T23:37:52+00:00

This patch adds scanf, sscanf, and fscanf entrypoints. It also adds unit
tests for sscanf and a basic test to fscanf. The scanf function is
basically impossible to test in an automated fashion due to it recieving
user input.
