[analyzer] Prevent triplicate warnings for `sarif-html` (#158112) When `-analyzer-output=sarif-html` is specified, the analyzer was reporting each warning to the console three times. This is because the code to create the diagnostic consumers for `sarif-html` was calling the code for `sarif` and `html` separately, each of which also creates its own console text consumer. Then the `sarif-html` code itself created a third. The fix is to factor out the creation of the SARIF and HTML consumers from the text consumers, so `sarif-html` just calls the code to create the SARIF and HTML consumers without the text consumers. The same fix applies for `plist-html`. I've updated one of the SARIF tests to specify `sarif-html`. This test would fail in the regular `-verify` validation due to the triplicated warnings, but now passes with my fix. Fixes #158103 rdar://160383710
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.
