Load combine pass
...I can't find any backstory for this pass, why was it chosen to optimize the pattern in question in this way? What is the current status of this pass?
I have an alternative implementation for it locally. I implemented an instcombine rule similar to recognise bswap/bitreverse idiom. It relies on collectBitParts (Local.cpp) to determine the origin of the bits in a given or value. If all the bits are happen to be loaded from adjacent locations it replaces the or with a single load or a load plus bswap.
If the alternative approach sounds reasonable I'll post my patches for review.
