[llvm-dev] target triple in 3.8

[Frank Winter via llvm-dev]

I added your suggestion and am using this now

llvm::legacy::FunctionPassManager *functionPassManager = new 
llvm::legacy::FunctionPassManager(Mod);

llvm::PassRegistry &registry = *llvm::PassRegistry::getPassRegistry();
initializeScalarOpts(registry);

functionPassManager->add( new 
llvm::TargetLibraryInfoWrapperPass(llvm::TargetLibraryInfoImpl(targetMachine->getTargetTriple())) 
);


still,

LV: The Widest register is: 32 bits.


so, unfortunately no change.

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 x86-64 AVX ?
