Also, optimize Loop::verifyLoop, since it gets called a lot. Use searches on a sorted list of blocks instead of calling the "contains" function, as is done in other places in the Loop class, since "contains" does a linear search. Also, don't call verifyLoop from LoopSimplify or LCSSA, as the PassManager is already calling verifyLoop as part of LoopInfo's verifyAnalysis. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81221 91177308-0d34-0410-b5e6-96231b3b80d8

* instcombine transforms vector loads that are only used byChris Lattner2009-09-081-0/+13
| | | | | | | | | | | | | | | | | | | | | | extractelement operations into a bitcast of the pointer, then a gep, then a scalar load. Disable this when the vector only has one element, because it leads to infinite loops in instcombine (PR4908). This transformation seems like a really bad idea to me, as it will likely disable CSE of vector load/stores etc and can be better done in the code generator when profitable. This goes all the way back to the first days of packed types, r25299 specifically. I'll let those people who care about the performance of vector code decide what to do with this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81185 91177308-0d34-0410-b5e6-96231b3b80d8

This fixes a problem I ran into where extracting a function from a larger file caused the generated code to change (masking the problem I was trying to debug) because the allocator behaved differently. This changes the results for two X86 regression checks. stack-color-with-reg is improved, with one less instruction, but pr3495 is worse, with one more copy.
