2024-12-10[libc] move bcmp, bzero, bcopy, index, rindex, strcasecmp, strncasecmp to ↵Nick Desaulniers
strings.h (#118899) docgen relies on the convention that we have a file foo.cpp in libc/src/\<header\>/. Because the above functions weren't in libc/src/strings/ but rather libc/src/string/, docgen could not find that we had implemented these. Rather than add special carve outs to docgen, let's fix up our sources for these 7 functions to stick with the existing conventions the rest of the codebase follows. Link: #118860 Fixes: #118875

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

2022-10-14Revert "[libc] New version of the mem* framework"Sterling Augustine
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.

2022-10-12[libc] New version of the mem* frameworkGuillaume Chatelet
This version is more composable and also simpler at the expense of being more explicit and more verbose. This patch is not meant to be submitted but gives an idea of the change. Codegen can be checked in https://godbolt.org/z/6z1dEoWbs by removing the "static inline" before individual functions. Unittests are coming.
