Build error while linking `lib/libomp.so` when using FullLTO on llvm-git #63830

Open ms178 opened 1 year ago

ms178 commented 1 year ago

Compiling llvm-git with clang version 17.0.0 (1aecb0e000e4efaa347e836e7ac06e070559dc2c), there is a build error while linking lib/libomp.so when using FullLTO. This does not reproduce when using ThinLTO.

This seems to be a recent regression the last known good revision for me was llvm-git-17.0.0_r467022.758c4640c95c.

Maybe @jhuber6 or @MaskRay find some time to have a look at this?

Hm, re-testing with ThinLTO fails a bit later now. Trying without the polly-flags next, that should make the ThinLTO case work again.

jhuber6 commented 1 year ago

Might be a compiler or implementation bug that manifests when we allow full inlining. What would really help here is the IR that triggers the failure. You should be able to get that via -Wl,--save-temps in your flags and finding the temporary file for libomp.so. Judging by the stack trace this happens in opt so it's likely something going wrong with the IR and less LTO.

ms178 commented 1 year ago

Thanks for the hint, Joseph. As I experiment with different flags from time to time, it seems to be related to the use of the Polly-flags.

All is fine (edit: for this specific file - lib/libomp.so) when using this reduced set of flags:

For completeness, without the polly flags, I now see similar failures while linking bin/llvm-exegesis and lib/libLLVM-17git.so later on in the build.

This is all I could find in/tmp/makepkg/llvm-git/src/llvm-project/build/lib that carries libomp.so in its name after such a crash when using the polly-flags and thinLTO. I hope this helps.

libomp.so.0.0.preopt.bc.txt libomp.so.0.2.internalize.bc.txt libomp.so.0.4.opt.bc.txt libomp.so.0.5.precodegen.bc.txt libomp.so.index.bc.txt libomp.so.index.dot.txt libomp.so.resolution.txt

jhuber6 commented 1 year ago

Hm, if it crashed in opt I wouldn't assume there to be a precodegen.bc file. The goal would be that you get an IR file that reproduces the error if you run it with opt file.ll -passes='lto<O3>' with all the -mllvm options.

ms178 commented 1 year ago

Unfortunately I am starting at zero using opt or debugging such issues per se. With a little help of ChatGPT, I produced a libomp.ll with this command:

If that is not what you are looking for, please guide me through each step with all neccessary details.

Here is another one with the CFLAGS added to the command from above:

Can you provide the build instructions that led you to the crash. i mean the cmake command line. the command you've pasted above doesn't error out.

By the way, I've just re-checked with the problematic set of flags from the comment above .

This issue is still reproducible for me with that PKGBUILD on current llvm-git main with clang 18.0.0 (69b19f284836f6059355167f904a2ab9f4b96992) as host compiler (I haven't re-named the directory where the host compiler is located, so don't be confused that the directory is still named llvm17 below).

hiraditya commented 1 year ago

Do you have precompiled bitcode files somewhere? it could be that the compiler is unable to parse those bitcode files.

ms178 commented 1 year ago

@hiraditya I am afraid, I do not have these.

While libomp.so seems to link okay now, I get similar traces with FullLTO using clang 18.0.0 (3ac4ba37c05a0c8de7e6db154768eadf2bdb5195), this time during linking of llvm-exegesis and lib/libLLVM-18git.so:

It seems that the (many months old) PGO-Profile (uploaded here: https://github.com/llvm/llvm-project/issues/63830#issuecomment-1666952173) triggers this in the 64-bit llvm-git build. I cannot reproduce the issue without it nor in the 32-bit build.
