pray the formatting is OK. :-) )
A few new X86-64 xmame benchmarks, with speedups always less
than 20%.
During the tests I found 3 games that segfault or hang
consistently on 64-bit, but run fine on 32-bit.
soldivid: crash immediately
stunrun: crash in attract mode
biofreak: hang on black screen
I went back and compiled xmame-0.82.1 in X86-64 mode with -O
and get the same segfaults. This is with gcc-3.3.3. Can
anyone else confirm this problem (esp. with another gcc
version)? If so I could post it to mametesters, else just
chalk it up to an old gcc or something else. Thanks!
