Is it possible to reproduce the result of opt -O3 manually?
...hods that accept arguments
too. These methods call non-default pass constructors, which in turn cause
the passes to behave in a different manner.
eg:
Pass *llvm::createLICMPass() { return new LegacyLICMPass(); }
Pass *llvm::createLICMPass(unsigned LicmMssaOptCap,
unsigned LicmMssaNoAccForPromotionCap) {
return new LegacyLICMPass(LicmMssaOptCap, LicmMssaNoAccForPromotionCap);
}
or
Pass *createLoopVectorizePass() { return new LoopVectorize(); }
Pass *createLoopVectorizePass(bool InterleaveOnlyWhenForced,
bool VectorizeOnlyWhenForced) {
return new LoopVectorize(In...

Is it possible to reproduce the result of opt -O3 manually?
Dear developers,
I am trying to reproduce the results of applying opt -O3 to a source file
in the form of LLVM IR. I want to get the same IR by manually ordering the
passes used by O3 and passing them to opt.
To illustrate what I am doing on an example, as an input I use linpack
benchmark from the LLVM test suite[1]:
1. First I produce the intermediate representation using clang:
clang -O3
