[Wine] Re: gcc -O3 -march=barcelona breaks Wine

[oiaohm]

KenSharp.  Bad news.  Wine only normally supports up to -O2 in the standard makefile config.

That -O3 works and gcc -O3 -march=barcelona fails suggests memory alignment issues.  

Those can be down right annoying to chase down.  Basically you have gone into the Gcc no mans land with -O3.

-O3 with gcc has been known in the past to make some copy-protection things fail.  Yes there is such thing as over optimizing wine.
