I’m sure they have, with respect to the overall optimization strategies.

(With some hand-written assembly.) So that’s a very weak compiler, comparatively. But then again, I doubt GCC intentionally has improved anything 586-related in decades. I seriously doubt they even test on P4s anymore.

Bah, just ask your friend (UHexen2 dude) to test for you! If anybody knows, he does. 😉

Its not all that bad!

  • AMD K5, K6, K6-2 (aka K6 3D), K6-3
  • DM&P/SiS Vortex86, Vortex86SX
  • Cyrix III, MediaGX, MediaGXm
  • IDT Winchip C6, Winchip 2
  • Intel Pentium, Pentium with MMX
  • Rise mP6
  • VIA C3 ‘Samuel 2’, C3 ‘Ezra’

So you have PII onward. A while back I had bench’d Quake with Visual C++, but doing the same with GCC shouldn’t be too hard. I’m not going to even try to build it with GCC 1.4 though. Although I guess if you can convert C++ comments into C comments, maybe it would work? I’m just not manually looking for // to /* */

just read debian news
“gcc for i386 has recently been changed
to target 686-class processors and is generating code that will crash
on other processors”

well F, there goes the Quake idea.
