hi, I have a piece of code which does roughly this (after inlining): Foo *foo1 = bar (ctx); foo1->something (); Foo *foo2 = bar (ctx); foo2->something (); bar is a function which will always return the same value if its input is the same value (and ctx is constant over the function body) so, I would like to instruct gcc that he can optimize away the second call to bar but I could not find any obvious way to do this. Is this a really stupid idea or did I miss something obvious ? Mathieu -- Mathieu Lacage <mathieu.lacage@xxxxxxxxx>
