AT&T's 3B2 C compilers have done this since (at least) Issue 3.
There are flags to the optimizer that tell it how much expansion
it can do (time-vs-space tradeoffs), and there are assembler
macros as well.  Warning: inline expansion make disassembly quite
difficult :-).

P.S. - anybody wanting info on how to invoke this on the 3B2 can
       send mail to me.
