NFC for builds with LLVM_EXPERIMENTAL_KEY_INSTRUCTIONS=OFF (default). In an ideal world we would be able to track that the merged location is used in multiple source atoms. We can't do this though, so instead we arbitrarily but deterministically pick one. In cases where the InlinedAt field is unchanged we keep the atom with the lowest non-zero rank (highest precedence). If the ranks are equal we choose the smaller non-zero group number (arbitrary choice). In cases where the InlinedAt field is adjusted we generate a new atom group. Keeping the group wouldn't make sense (a source atom is identified by the group number and InlinedAt pair) but discarding the atom info could result in missed is_stmts. Add unittest in MetadataTest.cpp.
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.
