[libc][bug] Fix out of bound write in memcpy w/ software prefetching (#90591)

2024-05-14T11:55:24+00:00

This patch adds tests for `memcpy` and `memset` making sure that we
don't access buffers out of bounds. It relies on POSIX `mmap` /
`mprotect` and works only when FULL_BUILD_MODE is disabled.

The bug showed up while enabling software prefetching.
`loop_and_tail_offset` is always running at least one iteration but in
some configurations loop unrolled prefetching was actually needing only
the tail operation and no loop iterations at all.

[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.

2023-02-07T19:45:51+00:00

This part of the effort to make all test related pieces into the `test`
directory. This helps is excluding test related pieces in a straight
forward manner if LLVM_INCLUDE_TESTS is OFF. Future patches will also move
the MPFR wrapper and testutils into the 'test' directory.

[libc] Improve testing of mem functions

2022-11-02T08:55:46+00:00

This patch extracts the testing logic from `op_tests.cpp` into
`memory_check_utils.h` so we can reuse it for mem* function integration
tests.

This makes testing consistent and thorough.
For instance this catches a bug that got unnoticed during submission of
D136595 and D135134. Integration test for memcmp was only testing a
single size.

This also leverages ASAN to make sure that data is not read / written
outside permitted boundaries
