When we inline a callee into a caller, the compiler needs to make sure that the caller supports a superset of instruction sets that the callee is allowed to use. Normally, we check for the compatibility of target features via functionsHaveCompatibleAttributes, but that happens after we decide to honor call site attribute Attribute::AlwaysInline. If the caller contains a call marked with Attribute::AlwaysInline, which can happen with __attribute__((flatten)) placed on the caller, the caller could end up with code that cannot be lowered to assembly code. This patch fixes the problem by checking the target feature compatibility before we honor Attribute::AlwaysInline.

The LLVM Compiler Infrastructure
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.
Getting the Source Code and Building LLVM
Consult the Getting Started with LLVM page for information on building and running LLVM.
