[mlir][acc] Handle OpenACC host_data in LegalizeDataValues (#134767)
`LegalizeDataValuesInRegion` is intended to replace the SSA values used
in a region with the output of data operations, but misses the handling
of the OpenACC `host_data` construct. As a result, currently
```
!$acc host_data use_device(%var)
...%var...
!$acc end host_data
```
is lowered to
```
%dev_var = acc.use_device(%var)
acc.host_data data_operands(%dev_var) {
...%var...
}
```
This pull request updates the LegalizeDataValuesInRegion to handle
HostDataOp such that lowering results in
```
%dev_var = acc.use_device(%var)
acc.host_data data_operands(%dev_var) {
...%dev_var...
}
```
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.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
