[LLVMdev] Remove identical or redundant basic blocks?
...erge
the ret instructions (and not the blocks).)
The -simplifycfg pass does not affect my code at all. Moreover,
according to 'StandardPasses.h' I guess the pass already runs (about 4
times) as a part of -O3. I have yet not looked at the actual code of
simplifycfg but the comment in 'StandarPasses.h' says it should merge
and eliminate basic blocks.
include/llvm/Support/StandardPasses.h, line 129 (SVN-97366):
PM->add(createCFGSimplificationPass()); // Merge & remove BBs

The unify exit return node (-mergereturn?) pass should take care of the
first example. The -simplifycfg option might take care of the second
example. Both work on LLVM IR.

Would it make sense to have a similar pass that operates on llvm main IR?
