FrontendActions.cpp is currently one of the biggest compilation units in all of flang. Measuring its compilation gives the following metrics: User time (seconds): 139.21 System time (seconds): 4.65 Maximum resident set size (kbytes): 5891440 (5.61 GB) This commit separates out explicit invocations of the parser into a separate compilation unit - ParserActions.cpp - through helper functions in order to decrease the maximum compilation time and memory usage of a single unit. After the split, the measurements of FrontendActions.cpp are as follows: User time (seconds): 70.08 System time (seconds): 3.16 Maximum resident set size (kbytes): 3961492 (3.7 GB) While the ones for the newly created ParserActions.cpp as follows: User time (seconds): 104.33 System time (seconds): 3.37 Maximum resident set size (kbytes): 4185600 (3.99 GB) --------- Signed-off-by: Kajetan Puchalski <kajetan.puchalski@arm.com>
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.
Getting the Source Code and Building LLVM
