Pu7o Posted February 11, 2006 Share Posted February 11, 2006 Since by default the GCC provided with XCode builds code with SSE3 instructions, and optimized for Pentium M, some of the code in universal apps has to be emulated by maxxuss' patch if you're running on a non-SSE3 processor. So, I decided to recompile gcc myself and set it to, by default, generate only SSE2 instructions. (I.e. basically, install this thing and any apps you compile will run a bit faster on hacked machines). Don't even think about installing this on a ppc mac, it won't work, and you'll break your build environment. Download link: REMOVED Enjoy!

antrunix Posted February 11, 2006 Share Posted February 11, 2006 Very dangerous for installation : stopped at Mac OSX "blue bar" and CPU getting very very hot (centrino). Don't use it (10.4.3 8f1111g Jas 4.2b patch SSE3 emul). TOTAL RE-INSTALLATION OF MY SYSTEM ...

Pu7o Posted February 14, 2006 Author Share Posted February 14, 2006 OK, link removed until I find what the hell is going on with all these problems and fix them. My installation suffered the same problem, but I had no idea it could be this gcc's fault because I did several system-level changes at the same time. It's very likely that it's libgcc's fault. Would anyone with a working system please post the following files from their system? (10.4.3 preferably) /usr/lib/libgcc_s.1.dylib /usr/lib/libgcc_s.10.4.dylib /usr/lib/libgcc_s.10.5.dylib Link to comment https://www.insanelymac.com/forum/topic/8878-sse2-optimizing-gcc/#findComment-56282 Share on other sites More sharing options...
Eggman Posted February 14, 2006 Share Posted February 14, 2006 Here are the unmodified GCC's from 8F1111g. GCCs.zip Link to comment https://www.insanelymac.com/forum/topic/8878-sse2-optimizing-gcc/#findComment-56284 Share on other sites More sharing options...
Pu7o Posted February 14, 2006 Author Share Posted February 14, 2006 Thanks, that got my system working Tomorrow I'll release a package that doesn't obliterate your system. Also, since my system is 8F1099, it's good to know that the dylib files work across both versions Link to comment https://www.insanelymac.com/forum/topic/8878-sse2-optimizing-gcc/#findComment-56305 Share on other sites More sharing options...
quixos Posted February 14, 2006 Share Posted February 14, 2006 i had no idea why that happened to me. yikes! Link to comment https://www.insanelymac.com/forum/topic/8878-sse2-optimizing-gcc/#findComment-56308 Share on other sites More sharing options...
