are there any instructions on how to build mlir-hlo and llvm to experiment
with this PR ? I'm personally curious to see how this works but I'm not
observing any instructions as to how to configure mlir-hlo project alongside
this work.
I've tried the build instructions from the mlir-hlo GitHub project.
build_tools/build_mlir.sh ${PWD}/llvm-project/ ${PWD}/llvm-build
Then to build this PR, I rebased the config.cmake with trivial rebasing
issues and then set
set(USE_MLIR
/home/ramana/work/tvm/tvm-mlir-trial-with-hlo/mlir-hlo/mlir-hlo/llvm-build)
set(USE_MHLO ON)
I realised I also needed to set LLVM_PROJ_SRC and LLVM_PROJ_BUILD in my
environment to try and build this which I've set to
LLVM_PROJ_SRC=/home/ramana/work/tvm/tvm-mlir-trial-with-hlo/mlir-hlo/mlir-hlo/
LLVM_PROJ_BUILD=/home/ramana/work/tvm/tvm-mlir-trial-with-hlo/mlir-hlo/mlir-hlo/llvm-build/
And then doing a cmake .. gives me the following error.
CMake Error at cmake/modules/contrib/MLIR.cmake:73 (message):
MLIREDSC not found, did you forget to build llvm-project?
Call Stack (most recent call first):
cmake/modules/contrib/MLIR.cmake:87 (find_mlir_lib)
CMakeLists.txt:413 (include)
