[libc] Add more robust compile time architecture detection

2021-11-02T11:00:33+00:00

We may want to restrict the detected platforms to only `x86_64` and `aarch64`.
There are still custom detection in api.td but I don't think we can handle these:
 - config/linux/api.td:205
 - config/linux/api.td:199

[libc][nfc] move ctype_utils and FPUtils to __support

2021-08-06T17:29:41+00:00

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.

[libc] Move FPExceptMatcher out of TestHelpers.h

2021-07-30T23:44:29+00:00

TestHelpers.h pulls few pieces from LLVM libc's unittest framework
which aren't available on platforms like Fuchsia which use their own
unittest framework. So, by moving FPExceptMatcher to a different file
we can exclude LLVM libc specific pieces in a cleaner way.

In a later pass, it might make more sense to rename TestHelpers.h also
to FPMatcher.h. That way, we can make macros like EXPECT_FP_EQ to be
equivalent to EXPECT_EQ on platforms like Fuchsia.

[libc] Accommodate Fuchsia's death test framework in fenv tests.

2021-07-23T22:19:04+00:00

Fuchsia's death test framework runs the closure which can die in a
different thread. Hence, the FP exceptions which cause the closure to
die should be enalbed in the closure.

[libc] Rename FEnv.h and refactor subsequent files

2021-07-22T00:07:39+00:00

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, , 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  was being used.

[libc] Add a new test matcher for tests raising floating point exceptions.

2021-07-21T04:59:39+00:00

This new matcher does not use death tests to check if SIGFPE is raised.
Instead, that a SIGFPE was raised is checked using a SIGFPE signal handler.
