Minor optimizations to DW_OP_LLVM_extract_bits_* (#163812) I noticed a couple more small optimization opportunities when generating DWARF expressions from the internal DW_OP_LLVM_extract_bits_* operations: * DW_OP_deref can be used, rather than DW_OP_deref_size, when the deref size is the word size. * If the bit offset is 0 and an unsigned extraction is desired, then sometimes the shifting can be skipped entirely, or replaced with DW_OP_and.
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.
