[LLVMdev] How to eliminate PHI nodes on pointer types?
...One more note, this particular optimization problem only seems to occur
in llvm 2.8, not 3.0 - though I can't say for sure whether it never
happens in 3.0.
Here's an example from the compiled code:
define private void @"vop_bindST at FFIFFI"(double* %news, double* %ss,
i32* %isSConnected, double* %newt, double* %tt, i32* %isTConnected)
nounwind alwaysinline {
entry:
%"reg2mem alloca point" = bitcast i32 0 to i32
%isSConnected1 = load i32* %isSConnected
%0 = icmp eq i32 %isSConnected1, 0
br i1 %0, label %false, label %true
true:...
