Inlining with optimization can really help, for very small functions. If
the code required for making the call is larger than the functionality, you
get smaller code. If you've only got one call to a function, you also get
smaller code. Inlined code can also be optimized more because you have the
context of the calling function.
In general, its a case-by-case thing. One problem with inlining on the Palm
with CW is local variables -- CWPalmOS doesn't do stack coloring yet, so if
a variable can't fit into a register, it will get a unique offset on the
stack, which leads to much larger stack usage than necessary.
