Fixing the location attribute added to mapInfoOp (#90764) Named location attribute added to `tgt_offload_entry` shall be used by runtime calls like `ompx_dump_mapping_tables` to print the information of variables that are mapped to the device. `ompx_dump_mapping_tables` was printing the wrong location information and this change fixes it. A sample execution of example before the change: ``` omptarget device 0 info: OpenMP Host-Device pointer mappings after block at libomptarget:0:0: omptarget device 0 info: Host Ptr Target Ptr Size (B) DynRefCount HoldRefCount Declaration omptarget device 0 info: 0x0000000000206df0 0x00007f02cdc00000 20000000 1 0 <program-file-loc> at unknown:18:35 ``` The change replaces unknown to the mapped symbol and location to the declaration location.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
