[compiler-rt][CMake] Pass all flags to _Float16 try-compile (#133952)
The try-compile mechanism requires that `CMAKE_REQUIRED_FLAGS` is a
space-separated string instead of a list of flags. The original code
expanded `BUILTIN_FLAGS` into `CMAKE_REQUIRED_FLAGS` as a
space-separated string and then would overwrite `CMAKE_REQUIRED_FLAGS`
with `TARGET_${arch}_CFLAGS` prepended to the unexpanded
`BUILTIN_CFLAGS_${arch}`. This resulted in the first two arguments being
passed into the try-compile invocation, but dropping the other arguments
listed in `BUILTIN_CFLAGS_${arch}`.
This patch appends `TARGET_${arch}_CFLAGS` and `BUILTIN_CFLAGS_${arch}` to
`CMAKE_REQUIRED_FLAGS` before expanding CMAKE_REQUIRED_FLAGS as a
space-separated string. This passes any pre-set required flags, in addition to
all of the builtin and target flags to the Float16 detection.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.
