Missed tail call optimization when local address could escape but not on the condition: void f(void); void f1(int *);
void g(int i, int j) { if (j) return f(); return f1(&i); } This might be a reduced testcase from fold_binary to fold_build2 where we have this issue, but I have not looked through all of the conditionals to see if this is true. -- Summary: missed tail call optimization when local address could escape Product: gcc Version: 4.1.0 Status: UNCONFIRMED Keywords: missed-optimization Severity: enhancement Priority: P2 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: pinskia at gcc dot gnu dot org CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21093
