2021-01-21[libc] Distinguish compiler and run failuresPetr Hosek1-2/+4
This is useful for debugging issues, for example when cross-compiling. Differential Revision: https://reviews.llvm.org/D95118
2021-01-20[libc][NFC][obvious] fix the names of MPFR testsMichael Jones6-21/+30
I missed the MPFR tests in my previous commit. They have now been fixed to not fail the prefix check in the test macro.
2021-01-20[libc][NFC] add "LlvmLibc" as a prefix to all test namesMichael Jones121-443/+487
Summary: Having a consistent prefix makes selecting all of the llvm libc tests easier on any platform that is also using the gtest framework. This also modifies the TEST and TEST_F macros to enforce this change moving forward. Reviewers: sivachandra Subscribers:
2021-01-19[libc] Extend the current fenv functions to aarch64.Siva Chandra3-0/+213
This change does not try to move the common parts of x86 and aarch64 and build few abstractions over them. While this is possible, x86 story needs a bit of cleanup, especially around manipulation of the mxcsr register. Moreover, on x86 one can raise exceptions without performing exception raising operations. So, all of this can be done in follow up patches.

2021-01-14[libc] Use #undef isascii in specific headerRoland McGrath3-8/+4
Standard C allows all standard headers to declare macros for all their functions. So after possibly including any standard header like <ctype.h>, it's perfectly normal for any and all of the functions it declares to be defined as macros. Standard C requires explicit `#undef` before using that identifier in a way that is not compatible with function-like macro definitions. The C standard's rules for this are extended to POSIX as well for the interfaces it defines, and it's the expected norm for nonstandard extensions declared by standard C library headers too. So far the only place this has come up for llvm-libc's code is with the isascii function in Fuchsia's libc. But other cases can arise for any standard (or common extension) function names that source code in llvm-libc is using in nonstandard ways, i.e. as C++ identifiers. The only correct and robust way to handle the possible inclusion of standard C library headers when building llvm-libc source code is to use `#undef` explicitly for each identifier before using it. The easy and obvious place to do that is in the per-function header. This requires that all code, such as test code, that might include any standard C library headers, e.g. via utils/UnitTest/Test.h, make sure to include those *first* before the per-function header. This change does that for isascii and its test. But it should be done uniformly for all the code and documented as a consistent convention so new implementation files are sure to get this right.

2021-01-13[libc][NFC] change isblank and iscntrl from implicit castingMichael Jones2-2/+2

2021-01-13[libc][NFC] add macro for fuchsia to switch test backend to zxtestMichael Jones5-253/+292
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).

This is a continuation of the previous CL which did a similar change in other tests. To elaborate a little about why we need this - under C++ compilation with headers not from LLVM libc, libraries like libc++ and libstdc++ provide their own math.h which undefine macros like `isnan` and provide the overloaded C++ isnan functions which return a boolean value instead of an integer value returned by the isnan macro.
