------- Comment #4 from pinskia at gcc dot gnu dot org 2007-06-29 03:05 ------- Note we should also optimize: int f(int a, int b) { int c = a+4; int d = c*2; int e = a*2; int f = e+4; return f+d; }
into "a*2 + 12;" (or "(a+6)*2" ) so that only one mutliplication is there. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32120
