[LLVMdev] Potential SimplifyCFG optimization; hammock to diamond transformation
All, I have some code that looks like the following: { double a, b, c; for (...) { ... a = lots of FP math; b = lots of FP math; c = lots of FP math; if (cond) { a = 0.0; b = 0.1; c = 0.2; } ... } } Could we not convert the hammock into a diamond and move the initial computation of a, b, and c into the else block. Something like this: {
