ARM: Remove redundant or buggy config of __aeabi_d2h (#152126)
This was set if `TT.isTargetAEABI()`. This was previously set above
if `TM.isAAPCS_ABI() && (TT.isTargetAEABI() || TT.isTargetGNUAEABI() ||
TT.isTargetMuslAEABI() || TT.isAndroid())`.
So this could differ based on a manually specified -target-abi flag due
to the `isAAPCS_ABI` part of the original condition. I'm guessing
these should be consistent, so either this second group of
setLibcallImpl
calls should have been guarded by the `isAAPCS_ABI` check, or the first
condition should remove it.
There doesn't appear to be any meaningful test coverage using the
manually specified ABI option, so #152108 tries to remove it
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.
