Need help in understanding llvm optimization
Hi,
I have below code in C -
int main() {
double x,y;
x = 1e16;
y = (x + 1) - x;
printf("y:%e\n", y);
return 0;
}
llvm bitcode looks like this for this function -
; Function Attrs: nounwind uwtable
define dso_local i32 @main() local_unnamed_addr #0 {
entry:
%call = tail call i32 (i8*, ...) @printf(i8* getelementptr inbounds ([4 x
i8], [4 x i8]* @.str, i64 0, i64
