This reverts commit 1e6e845d49a336e9da7ca6c576ec45c0b419b5f6 because it changed the 1st parameter of adjust() to be unsigned, but libc itself calls adjust() with a negative argument in align_backward() in op_generic.h.

2023-03-20[libc] Make string tests compatible with the Fuchsia buildRoland McGrath
Some test code was doing loose conversions caught by compiler warnings in the Fuchsia build. This included duplicated code in a few tests that was reconsolidated with the existing header file copy of the same functions. The MemoryMatcher abstraction presumes gtest-style matcher support, which is not available in Fuchsia's zxtest library. It's avoided in favor of simpler memory-comparing assertions.

2023-02-07[libc][NFC] Move UnitTest and IntegrationTest to the 'test' directory.Siva Chandra Reddy
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.
2022-11-02[libc] Improve testing of mem functionsGuillaume Chatelet
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 Differential Revision: https://reviews.llvm.org/D136865

This reverts commit https://reviews.llvm.org/D135134 (b3f1d58a131eb546aaf1ac165c77ccb89c40d758) That revision appears to have broken Arm memcpy in some subtle ways. Am communicating with the original author to get a good reproduction.

2022-02-08[libc] Optimized version of memmoveGuillaume Chatelet
This implementation relies on storing data in registers for sizes up to 128B. Then depending on whether `dst` is less (resp. greater) than `src` we move data forward (resp. backward) by chunks of 32B. We first make sure one of the pointers is aligned to increase performance on large move sizes. Differential Revision: https://reviews.llvm.org/D114637
