[LLVMdev] Potential SimplifyCFG optimization; hammock to diamond transformation
All,
I have some code that looks like the following:
{
double a, b, c;
for (...) {

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:
