In this code:
|
||||||
|
|
||||||
|
long foo(long x) {
|
||||||
|
return x > 1 ? x : 1;
|
||||||
|
}
|
||||||
|
|
||||||
|
LLVM emits a comparison with 1 instead of 0. 0 would be equivalent
|
||||||
|
and cheaper on most targets.
|
||||||
|
|
||||||
|
LLVM prefers comparisons with zero over non-zero in general, but in this
|
||||||
|
case it choses instead to keep the max operation obvious.
