AArch64 uses $d and $x symbols to delimit data embedded in code. However, sometimes we see $d symbols, typically in .eh_frame, with addresses that belong to different sections. These occasionally fall inside .text functions and cause BOLT to stop disassembling, which in turn causes DWARF CFA processing to fail. As a workaround, we just ignore symbols with addresses outside the section they belong to. This behaviour is consistent with objdump and similar tools.
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.
