[LLVMdev] LSR is Unbearably Slow
I just filed bug 7872 about non-scalability of the LSR analysis
algorithms. It may be related to bug 6727.
The fundamental problem appears to be re-running SCEV analyses such as
properlyDominates and SCEVComplexityCompare over and over again on large
SCEV expressions. Memoizing results for SCEVComplexityCompare appears
to help significantly but that is much harder to do with things like
properlyDominates.
Is anyone actively looking at LSR compile time issues? LLVM 2.7 is
taking on th...
