2012-03-13Address some review comments from Duncan. This moves the iterativeChandler Carruth
offset accumulation to use a boring APInt instead of ConstantExprs. I didn't go all the way to an 'int64_t' because I wanted APInt to handle any magic required to properly wrap the arithmetic when the pointer width is <64 bits. If there is a significant penalty from using APInt here, first off WTF, and secondly let me know and I'll do the math by hand. I've left one layer still operating w/ ConstantExpr because it makes the interface quite a bit simpler, and that one isn't iterative so has much lower cost. I suppose this may potentially speed up some strang compilation situations, but I don't really expect much. It should have no functional impact either way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152590 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-12When inlining a function and adding its inner call sites to theChandler Carruth
candidate set for subsequent inlining, try to simplify the arguments to the inner call site now that inlining has been performed. The goal here is to propagate and fold constants through deeply nested call chains. Without doing this, we loose the inliner bonus that should be applied because the arguments don't match the exact pattern the cost estimator uses.

2012-03-12Teach instsimplify how to constant fold pointer differences.Chandler Carruth
Typically instcombine has handled this, but pointer differences show up in several contexts where we would like to get constant folding, and cannot afford to run instcombine. Specifically, I'm working on improving the constant folding of arguments used in inline cost analysis with instsimplify. Doing this in instsimplify implies some algorithm changes. We have to handle multiple layers of all-constant GEPs because instsimplify cannot fold them into a single GEP the way instcombine can. Also, we're only interested in all-constant GEPs. The result is that this doesn't really replace the instcombine logic, it's just complimentary and focused on constant folding.

2012-03-10Make this transformation slightly less agressive and more correct.Bill Wendling
The 'CmpInst::isFalseWhenEqual' function returns 'false' for values other than simply equality. For instance, it returns 'false' for <= or >=. This isn't the correct behavior for this transformation, which is checking for strict equality and non-equality. It was causing the gcc.c-torture/execute/frame-address.c test to fail because it would completely (and incorrectly) optimize a whole function into a 'ret i32 0'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152497 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-10Implement a more intelligent way of spilling uses across an invoke boundary.Bill Wendling
The old way of determine when and where to spill a value that was used inside of a landing pad resulted in spilling that value everywhere and not just at the invoke edge. This algorithm determines which values are used within a landing pad. It then spills those values before the invoke and reloads them before the uses. This should prevent excessive spilling in many cases, e.g. inside of loops. <rdar://problem/10609139> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152486 91177308-0d34-0410-b5e6-96231b3b80d8
