If I dump the Module, it starts with: ; ModuleID = 'module' target datalayout = "e-m:e-i64:64-f80:128-n8:16:32:64-S128" Does this datalayout look good for x8...

I've tried to do: clang++ -O3 -march=native -mtune=native \ -Rpass=loop-vectorize,slp-vectorize -Rpass-missed=loop-vectorize,slp-vectorize -Rpass-analysis=loop-vectorize,slp-vectorize \ -ffast-math -ffp-model=fast -ffp-exception-behavior=ignore -ffp-contract=fast \ -c -o vec.o vec.cc But I've got no feedback. -- Alexandre Bique

I have some trouble making the SIMD vector length visible to the passes. My application is basically on the level of 'opt'. What I did in version 3.6 was functionPassManager->add(new llvm::TargetLibraryInfo(llvm::Triple(Mod->getTargetTriple()))); functionPassManager->add(new llvm::DataLayoutPass()); and then the -basicaa and -loop-vectorizer were able to vectorize the input

The information needs to be serialised into IR, so that a multi-step compilation (clang->llc) picks up the details. Otherwise, we'd be vectorising when coming from Clang and not when passing through opt/llc. Admittedly, o...

...ing multiple global functions defined >(something like weak linkage?), I don't have a better idea right now. I am not sure I understand here. In my patch, all I am doing is “vector symbol awareness generation”. There are no globals that are generated in the final object file, it is just the TargetLibraryInfoImpl that is being populated with the info needed by the vectorizer.

...therefore need to be able to register intrinsics and I believe this is impossible without a target (and even if it is, it makes less sense than a target that doesn’t use ISel/MC). Not being able to use intrinsics is a complete deal breaker. *Basic optimisations (basic CSE,DCE,inlining): requires a TargetLibraryInfoImpl(?) which I believe requires a target. While not strictly necessary it would improve the readability of the resulting IR/SPIRV. All of the more complex optimisations would be done “post ingestion” of the SPIRV and with a different target triple so are unaffected by any decision made. See my reply to...
