[NVPTX] Fix for LTO dwarf emission when multiple CUs with a mix of DebugDirectivesOnly and NoDebug (#190371) Only emit the initial .loc dwarf directive if the CU requires debug information. When a module contains multiple CUs where one is DebugDirectiveOnly and the rest are NoDebug, we attempt to emit dwarf for the NoDebug compile units leading to an assertion when calling emitDwarfFile0Directive when in getOrCreateDwarfCompileUnit. I added a lit test for this case which used to assert.
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.
