[libc][NFC] Cleanup time.h (#122027) 2025-01-08T20:28:50+00:00 Michael Jones michaelrj@google.com 2025-01-08T20:28:50+00:00 f9c2377fb68e5051b3061186c507f7b87db2a8b2 While working on strftime I noticed some constants were being defined in unexpected places. One thing led to another, and I ended up doing a major cleanup of the time functions. What's included: All uses of <time.h> in /src and /test removed (except for LibcTest.cpp) The various time constants have been moved to time_constants.h, and the `time_constants` namespace. struct tm gets its own type indirection header now.

unexpected places. One thing led to another, and I ended up doing a

All uses of <time.h> in /src and /test removed (except for LibcTest.cpp)
The various time constants have been moved to time_constants.h, and the

 [libc][NFC] Introduce a Sign type for FPBits (#78500) 2024-01-18T12:40:49+00:00 Guillaume Chatelet gchatelet@google.com 2024-01-18T12:40:49+00:00 11ec512f444986c5cf09ad8b5c01a93063b21c4a Another patch is needed to cover `DyadicFloat` and `NormalFloat` constructors.

 [libc][NFC] Simplify `FPBits` (#76835) 2024-01-04T15:14:28+00:00 Guillaume Chatelet gchatelet@google.com 2024-01-04T15:14:28+00:00 d02471ede56e727d7d16f61bcdecc4f99a2bda02 This patch reduces the scope of `FPBits` exported variables and functions. It also moves storage up into `FPRep` and tries to make the default and specialized versions of `FPBits` more uniform. The next step is to move the specialization from `FPBits` to `FPRep` so we can manipulate floating point representations through `FPType` alone - that is - independently from the host architecture.

 [libc] Make ErrnoSetterMatcher handle logging floating point values. 2023-05-26T06:24:51+00:00 Siva Chandra Reddy sivachandra@google.com 2023-05-15T22:12:26+00:00 4f1fe19df385445fabde47998affca50c7f1bc1e Along the way, couple of additional things have been done: 1. Move `ErrnoSetterMatcher.h` to `test/UnitTest` as all other matchers live there now. 2. `ErrnoSetterMatcher` ignores matching `errno` on GPUs.

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.
