[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.

FPUtils was moved to simplify the build order, and to clarify which

[libc] Rename FEnv.h and refactor subsequent files 2021-07-22T00:07:39+00:00 Hedin Garca hedingarcia@google.com 2021-07-21T18:12:29+00:00 049cfc464d1718c5cd97fa8a8ddf0fc36e101f98 Because Windows's pathnames are not case sensitive, to avoid include conflicts between our header file FEnv.h and the one from the C Standard library, <fenv.h>, the prior file was renamed. The motive for the relabel came to fix this include error in TestHelpers.cpp since a conflict arose with a file in the same directory when #include <fenv.h> was being used.

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.
