[libc] Migrate ctype_utils to use char instead of int where applicable. (#166225) 2025-11-05T19:02:28+00:00 Alexey Samsonov vonosmas@gmail.com 2025-11-05T19:02:28+00:00 120689e46679c6db37cd9e839ec0721e80a22d4f 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.

 [libc] Add `ctype.h` locale variants (#102711) 2024-08-22T18:51:54+00:00 Joseph Huber huberjn@outlook.com 2024-08-22T18:34:48+00:00 856dadb33c38f4e3be592f11c3d67e7337e288c7 Summary: This patch adds all the libc ctype variants. These ignore the locale ingormation completely, so they're pretty much just stubs. Because these use locale information, which is system scope, we do not enable building them outisde of full build mode.

[libc][nfc] move ctype_utils and FPUtils to __support 2021-08-06T17:29:41+00:00 Michael Jones michaelrj@google.com 2021-08-05T21:27:29+00:00 c120edc7b3e1907127c3107b30e2667f1fde1ee2 Some ctype functions are called from other libc functions (e.g. isspace is used in atoi). By moving ctype_utils.h to __support it becomes easier to include just the implementations of these functions. For these reasons the implementation for isspace was moved into ctype_utils as well. FPUtils was moved to simplify the build order, and to clarify which files are a part of the actual libc. Many files were modified to accomodate these changes, mostly changing the #include paths.
