Hi,
I assume this is expected behaviour to most, but it went against my
expected behaviour so thought I would share.
I was benchmarking some code and in the inner loop discovered that:
if true {
funcA()
} else {
funcB()
}
was slower than:
//if true {
funcA()
//} else {
// funcB()
//}
On the one hand: DUH! of course.
On the other I expected these kind of basic compile time optimisations to
be a thing.
So I assume the Go compiler doesn't try and do this analysis in a Compile
time vs Execution time tradeoff. It may also be that the compiler does try
and do this, but it didn't recognise it in my code.
Anyway Hope that is useful to someone. It has certainly changed the way I
will write my (profiled) inner loops.
Chris
