[LLVMdev] MCJIT generates MOVAPS on unaligned address
It's not reproducible with 'opt'. I call the SLP pass from my
application and only then the wrong IR gets generated.
On the attached module I call via the function pass manager:
1) TargetLibraryInfo with the target triple
2) Set the data layout
3) Basic Alias Analysis
4) SLP vectorizer
This produces the wrong IR. On the other hand running the attached
module through 'opt

target triple in 3.8
...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 IR for AVX.
Now, with 3.8 that didn't compile. What I do instead is just setting the
datalayout to the Module (got that from the Kaleido example).
Mod->setDataLayout( targetMachine->createDataLayout() );...

[LLVMdev] Looking for advice on how to debug a problem with C++ style exception handling code that my compiler generates.
Logan,
How would I dump the object file generated by the JIT compiler pipeline?
Could you point me to an example of how something like that is done? I’m used to working with the JIT machinery in memory but not writing object files out to disk.
I’m have code to generate object files for AOT compilation - is it done the same way?
Best,
.Chris.
