[Bug][LLVM] TVM fails to compile with LLVM 17

[supersat]

This is mostly an FYI/early warning that LLVM 17 seems to have introduced breaking changes.

Expected behavior

TVM compiles as expected.

Actual behavior

The following errors were emitted:

/home/kkoscher/Projects/tvm/src/target/llvm/codegen_amdgpu.cc:45:10: fatal error: 'llvm/Transforms/IPO/PassManagerBuilder.h' file not found
#include <llvm/Transforms/IPO/PassManagerBuilder.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

#include <llvm/Transforms/IPO/PassManagerBuilder.h>
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Other LLVM deprecation warnings are also emitted:

Environment

OS: Ubuntu 20.04
TVM hash: eecc02ad358367bacf461a7b0676231a1be6b6c3
llvm-project hash: 0b70f95c162634a06783081c6eda46d12cbcfd02

Steps to reproduce

Since LLVM 17 is currently in development, you must build LLVM 17 from source.

I used the following commands to build LLVM:

cmake -S llvm -B build -G Ninja -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_ENABLE_RUNTIMES="libcxx;libcxxabi;libunwind" -DCMAKE_BUILD_TYPE=RelWithDebInfo -DLLVM_PARALLEL_LINK_JOBS=1

cmake --build build

When building TVM, I run cmake with -DUSE_LLVM and -DCMAKE_CXX_COMPILER point to my built LLVM and Clang++ repsectively.

Triage

• needs-triage
• backend: llvm
• backend: nvptx

This also seems to affect AMD GPU (missing header) and Hexagon codegen (deprecation warnings).
