llvm-project.git/libc/src/threads/linux/mtx_lock.cpp, branch main Unnamed repository; edit this file 'description' to name the repository. [libc][NFC] Add a platform independent thread support library. 2022-03-04T18:33:46+00:00 Siva Chandra Reddy sivachandra@google.com 2022-02-26T01:18:19+00:00 a5ee8183c049d377539c2b6452c8817589dd2df4 The idea is that, other parts of the libc which require thread/lock support will be able to use this platform independent setup. With this change, only the linux implementation of a mutex type has been moved to the new library. Because of this, there is some duplication between the new library and src/threads/linux. A follow up change will move all of src/threads/linux to the new library. The duplication should be eliminated with that move.

[libc][NFC] Move the mutex implementation into a utility class. 2021-08-26T18:49:20+00:00 Siva Chandra Reddy sivachandra@google.com 2021-08-26T05:21:54+00:00 004c7b1da6cfea1d1f09535607a8c7c2f051e8d5 This allows others parts of the libc to use the mutex types without actually pulling in public function implementations. Along the way, few cleanups have been done, like using a uniform type to refer the linux futex word. Reviewed By: michaelrj Differential Revision: https://reviews.llvm.org/D108749

[libc] Switch to use a macro which does not insert a section for every libc function. 2021-01-08T23:52:35+00:00 Michael Jones michaelrj@google.com 2020-12-23T18:46:09+00:00 a0b65a7bcd6065688189b3d678c42ed6af9603db Summary: The new macro also inserts the C alias for the C++ implementations without needing an objcopy based post processing step. The CMake rules have been updated to reflect this. More CMake cleanup can be taken up in future rounds and appropriate TODOs have been added for them. Reviewers: mcgrathr, sivachandra Subscribers:
