...ed. Perhaps it is something I have done wrong, but my executions of llc are creating two FPPassManager objects (that run different sets of passes). FPPassManager contains a static char ID (as expected), so I expected only one FPPassManager object to be constructed during a single execution. LocalStackSlotAllocation::runOnMachineFunction returns true even when it has not changed the data (in any way that I can see). The destructor of SelectionDAGISel deletes MF, a pointer to a member variable the class did not new. Again, I'm too new to LLVM to know whether these things are as designed or un...

There is an optimization which the Greenhills compiler does for mips16. I have not looked at it myself ,but it was recounted to me. The basic idea is that if you have a large struct, rather than reference each element from the base of the struct, it's possible to chose some optimal point(s) that are not at the beginning of the struct and use as the base to reference elements of the
