Bizarre, I could swear that when I first tried your fix I got a call to
__muldi3, but I just updated expmed.c, reran the test case and I got the same
inlined sequence that I got before the patch. I think in the first case I had
reduced the cost of MULT on hppa64 and that is why I got the __divdi3 call. I
put the MULT cost back to where it was and now I get the inline sequence.
In short, the compilation now takes 30 seconds instead of 15 minutes and I get
the same code.
