Bug ID: 67879
Summary: unnecessary jump in ternary
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: marccelani at fb dot com
Target Milestone: ---
The following functions f and f2 should compile the same, but f includes a jump
whereas f2 properly avoids the jump and adds the result of the comparison.
int f(int a, int b, int* c) {
bool x = a < b;
return x ? *c : *c + 1;
}
int f2(int a, int b, int* c) {
bool x = a < b;
return *c + (x ? 0 : 1);
}
