Re: [Qemu-devel] Re: QEMU fails with different levels of compiler optimizati

[André Braga]

Uh... Not yet, but you have a point: it makes it more likely that the
critical code will fit the cache. I did not enable
-fomit-frame-pointer because it makes debugging a *pain in the rear*,
and sometimes I run QEMU under GDB just to see if I can narrow the
problem down to some specific part of the code. And so far it seems
that the mingw runtime breaks something with the Windows timing
functions if I run higher levels of optimization. I'm yet to try it
under Linux.
