I have a long inline function, called with all constant values, that
compiles down to a few instructions. However, if I slightly increase
the length of the function, constant propagation doesn't work any more
and the compiler generates dead code (the function is still inlined).
Is there a --param that will increase the constant propagation length?
Thanks!
