We were sizing the table appropriately for the number of LibcallImpls, but many of those have identical names which were pushing up the collision count unnecessarily. This ends up decreasing the table size slightly, and makes it a bit faster. BM_LookupRuntimeLibcallByNameRandomCalls improves by ~25% and BM_LookupRuntimeLibcallByNameSampleData by ~5%. As a secondary change, align the table size up to the next power of 2. This makes the table larger than before, but improves the sample data benchmark by an additional 5%.
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.
