[lldb/Breakpoint] Fix condition hash after updating condition text (#181409) StopCondition::SetText was computing the hash from the moved-from text parameter instead of the stored m_text member. After std::move(text), the source parameter becomes empty, causing the hash to always be computed from an empty string. This caused breakpoint condition updates to fail silently. When a user modified a condition (e.g., from "x == y" to "x > y"), the hash remained unchanged. Breakpoint locations use this hash to detect when conditions need re-evaluation, so with a stale hash they would continue using cached state for the old condition, triggering at incorrect locations. The patch fixes this issue by computing the hash from m_text after the move operation, ensuring it reflects the actual stored condition text. It also adds API test that updates a breakpoint condition and verifies the new condition is properly evaluated. rdar://170191229 Signed-off-by: Med Ismail Bennani <ismail@bennani.ma>
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
