This prevents useless spills to the same memory region from causing spilling to take too many passes to converge. Handling this at spilling time allows us to relax the generation of spill sections; specifically, multiple spills can now be generated per output section. This should be fairly benign for performance, and it would eventually allow linker scripts to express things like holes or minimum addresses for parts of output sections. The linker could then spill within an output section whenever address constraints are violated.
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.
