Revert "[lldb] Allow fetching of RA register when above fault handler (#98566)" This reverts commit fd424179dcb3417fc0675f77d2bf06c750dd1c33. This patch has two problems. First, it is unnecessary, Pavel landed a fix a week or so before mine which solves this problem in bbd54e08b08f5ccd38c4665178e65c58f7b14459 . Second, the fix is incorrect; for a function above a trap handler, where all registers are available, this patch would have lldb fetch the return address register from frame 0. This might be 10 frames up in the stack; the frame 0 return address register is incorrect. The change would have been correct a short bit later than this, but Pavel's fix is executed earlier in the function and none of this is needed.
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.
