[compiler-rt] Disable tests for unavailable builtins (#161275) The builtins `__fixunstfdi` and `__multc3` may be removed by the preprocessor depending on configuration flags. When this happens, the corresponding tests fail at link time due to missing definitions. Disable these tests when the builtins are not available. Also remove the XFAILs for aarch64 windows. As this test now became a no-op on platforms that lack CRT_HAS_128BIT or CRT_HAS_F128 (aarch64 windows lacks the latter), it no longer fails. This reapplies e9e166e54354330c474457711a8e7a7ca2efd731 and 656707086e5f6fccd2eb57f5aaf987c328c0f4f1 after fixing declarations of the builtins in the tests in b54250940c2cd70f911386b02239b50c165e5354. rdar://159705803 rdar://159705705 --------- Co-authored-by: Martin Storsjö <martin@martin.st>
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
