Hmm. I also have some patches (code generation and C++ bug fixes,
better ix86 code for 64-bit arithmetic, __builtin_constant_p in inline
functions). These patches are also about 2 years old. And I gave up
trying to integrate them also due to arguments with Richard Kenner.

Perhaps he was having a hard time back then?

Of course, I don't have the time to pursue integration now :-)

BTW, I have used -mregparm=1 throughout a 250,000 line C++ program and
only encountered one code generation bug, with an indirect function
call. In my example (which I reported in May 1997) the bug is quite
clear. I stopped working on the C++ program within a couple of days of
reporting that bug, so I had no interest in fixing it.

Having used -mregparm=1 extensively, I suggest it is actually very
reliable. -mregparm=2, =3 etc. perhaps not.

I used -mregparm=1 because it generally produced the smallest code. I
would have used -mrtd too, if __attribute__((regparm(0),cdecl)) worked
(it didn't).
