LibcTestMain.cpp	[libc] Add option to run specific tests This addition reads command line input to run specific single tests within a larger call to run all the tests for a particular function. When the user adds a second argument to the command line, the code skips all the tests that don't match the user's specified binary. If the user doesn't specify a test correctly and/or no tests are run, a failure message prints. Reviewed By: sivachandra, aeubanks Differential Revision: https://reviews.llvm.org/D105843	4 年前
MemoryMatcher.cpp	[libc] Optimized version of memmove 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	4 年前

Test.h	[libc][NFC] add macro for fuchsia to switch test backend to zxtest This moves utils/UnitTest/Test.[h/cpp] to LibcTest.[h/cpp] and adds a new Test.h that acts as a switcher so that Fuchsia can use the zxtest backend for running our tests as part of their build. FuchsiaTest.h is for including fuchsia's zxtest library and anything else needed to make the tests work under fuchsia (currently just undefining the isascii macro for the test). Downstream users, please fix your build instead of reverting. Reviewed By: sivachandra Differential Revision: https://reviews.llvm.org/D94625	5 年前

The LLVM libc unit test framework

This directory contains a lightweight implementation of a gtest like unit test framework for LLVM libc.

Why not gtest?

While gtest is great, featureful and time tested, it uses the C and C++ standard libraries. Hence, using it to test LLVM libc (which is also an implementation of the C standard libraries) causes various kinds of mixup/conflict problems.

How is it different from gtest?

LLVM libc's unit test framework is much less featureful as compared to gtest. But, what is available strives to be exactly like gtest.

Will it be made as featureful as gtest in future?

It is not clear if LLVM libc needs/will need every feature of gtest. We only intend to extend it on an as needed basis. Hence, it might never be as featureful as gtest.
