Well, I don't need a benchmark to tell you it wasn't worthwhile, as
you've dramatically reduced the performance of e-uae by building a 64
bit version, which cannot use JIT acceleration, as there is currently no
64 bit port of the JIT code.
The Basilisk II emulator /does/ have a 64 bit JIT for M68K, and Richard
Drummond (the e-uae devloper gone AWOL) did state he intended to port it
over to e-uae, but AFAIK he never got a round to it.
If that is still the case, then I think that should be a high priority
for any future work (puae?).
For now, stick to --march=i686, and ensure you have the 32 bit support
libraries (glibc et al).
