Windows heuristics try to detect old installer programs and run them as elevated. These heuristics include checking for certain substrings in file names, e.g. "patch", "update", "setup". When lit tries to run affected executables, it produces "[WinError 740] The requested operation requires elevation" instead. Several tests have been affected by this issue (see https://reviews.llvm.org/D137772, https://reviews.llvm.org/D148988, https://reviews.llvm.org/D149004). We should set this environment variable to disable this heuristic once and for all, instead of setting it in inidividual test suites. There should be no lit tests that legitimately want to run as elevated. Differential Revision: https://reviews.llvm.org/D149064
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.
