2025-11-05	[libc] Migrate ctype_utils to use char instead of int where applicable. ↵	Alexey Samsonov
	(#166225) Functions like isalpha / tolower can operate on chars internally. This allows us to get rid of unnecessary casts and open a way to creating wchar_t overloads with the same names (e.g. for isalpha), that would simplify templated code for conversion functions (see 315dfe5865962d8a3d60e21d1fffce5214fe54ef). Add the int->char converstion to public entrypoints implementation instead. We also need to introduce bounds check on the input argument values - these functions' behavior is unspecified if the argument is neither EOF nor fits in "unsigned char" range, but the tests we've had verified that they always return false for small negative values. To preserve this behavior, cover it explicitly.

2024-12-03	[libc] Change ctype to be encoding independent (#110574)	Michael Jones
	The previous implementation of the ctype functions assumed ASCII. This patch changes to a switch/case implementation that looks odd, but actually is easier for the compiler to understand and optimize.

2024-04-22	[libc] Clean up alternate test framework support (#89659)	Roland McGrath
	This replaces the old macros LIBC_COPT_TEST_USE_FUCHSIA and LIBC_COPT_TEST_USE_PIGWEED with LIBC_COPT_TEST_ZXTEST and LIBC_COPT_TEST_GTEST, respectively. These are really not about whether the code is in the Fuchsia build or in the Pigweed build, but just about what test framework is being used. The gtest framework can be used in many contexts, and the zxtest framework is not always what's used in the Fuchsia build. The test/UnitTest/Test.h wrapper header now provides the macro LIBC_TEST_HAS_MATCHERS() for use in `#if` conditionals on use of gmock-style matchers, replacing `#if` conditionals that test the framework selection macros directly.

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.
