Fixes a crash with the following alias, which I use for printing the contents of pointer variables: ``` command alias vp v -P1 ``` At some point in the recent-ish past, parsing this alias has started crashing lldb. The problem is code that assumes the option and its value are separate. This assumption causes an index past the end of a vector. This fix changes `FindArgumentIndexForOption`. The function now returns a pair of indexes, the first index is the option, the second index is the index of the value. In the case of joined options like `-P1`, the two indexes are the same.
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.
