This prepares for the upcoming change to simplify relocation recording in MCAssembler. While both MCAssembler::fixupNeedsRelaxation and MCAssembler::handleFixup call evaluateFixup and use shouldForceRelocation, the shouldForceRelocation logic is not supposed to be needed by MCAssembler::fixupNeedsRelaxation. The ARM special cases for interworking branches (https://reviews.llvm.org/D33436 and https://reviews.llvm.org/D33898) break the assumption. Switch to fixupNeedsRelaxationAdvanced and explicitly test the conditions.
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.
