[DA] Add option to run only SIV routines (#157084) This patch introduces a new option, `da-run-siv-routines-only`, which runs only the SIV family routines in the DA. This is useful for testing (regression tests, not dependence tests) as it helps detect behavioral changes in the SIV routines. Actually, regarding the test cases added in #157085, fixing the incorrect result requires changes across multiple functions (at a minimum, `exactSIVtest`, `gcdMIVtest` and `symbolicRDIVtest`). It is difficult to address all of them at once. This patch also generates the CHECK directives using the new option for `ExactSIV.ll` as it is necessary for subsequent patches. However, I believe it will also be useful for other `xxSIV.ll` tests. Notably, the SIV family routines tend to be affected by other routines, as they are typically invoked at the beginning of the overall analysis.
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.
