supersat opened a new issue, #14313:
URL: https://github.com/apache/tvm/issues/14313
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>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/kkoscher/Projects/tvm/src/target/llvm/codegen_nvptx.cc:48:10: fatal
error: 'llvm/Transforms/IPO/PassManagerBuilder.h' file not found
#include <llvm/Transforms/IPO/PassManagerBuilder.h>
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `
Other LLVM deprecation warnings are also emitted:
`/home/kkoscher/Projects/tvm/src/target/llvm/codegen_blob.cc:112:64:
warning: 'getABITypeAlignment' is deprecated: use getABITypeAlign instead

### 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:
`make -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).
