This patch partially prunes the windows container to reduce the image size, primarily to improve image pull time which is currently a pretty significant bottleneck in the new premerge due to autoscaling. This patch removes the following: - An extra copy of LLVM that is not needed anymore. - An unneeded perl installation - Some extra python packages that are specific to buildbot This overall saves about 4GB on the uncompressed image, or about 20%. I tested this locally against the premerge pipeline and everything passes. There are still several significant areas of opportunity, namely seeing if we can move away from the 4.8 sdk image to just the `windowsservercore` image (about 7GB of opportunity), and shrinking the VS installation (in total about 5GB uncompressed currently opportunity unknown).
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.
