[libc] fix behavior of strrchr(x, '\0') (#112620) 2024-10-30T22:08:03+00:00 George Burgess IV george.burgess.iv@gmail.com 2024-10-30T22:08:03+00:00 50c44478fe3f680374edf1363d2a3617b8ff2a0b `strrchr("foo", '\0')` is defined to point to the end of `foo`, rather than returning NULL. This wasn't caught by tests, since llvm-libc's `ASSERT_STREQ(nullptr, "");` is not an assertion error. While I'm here, refactor the test slightly to check for NULL more specifically. I considered adding fancier `ASSERT`s (and changing the semantics of `ASSERT_STREQ`), but opted for a more local fix by fair dice roll.

 [libc] Enable running libc unit tests on AMDGPU 2023-05-04T11:32:52+00:00 Joseph Huber jhuber6@vols.utk.edu 2023-05-03T14:19:11+00:00 632fa3798cc3cdb9d91867c1ae978809ec4bb253 The previous patches added the necessary support for global constructors used to register tests. This patch enables the AMDGPU target to build and run the unit tests on the GPU. Currently this only tests the `ctype` tests, but adding more should be straightforward from here on.
