The lines should wrap now.
does GCC 4.6 optimise for FMA4 and XOP.
FMA can fuse a multiply and an add into a single step, and so could give a big speed up to some code.
also wouldn't it be great if GCC had a 'fastest flags that don't break the test-suite' option.
You may need to get the code from the linux merge, I haven't tested if master still runs on linux, and Aras is mostly win/mac.
Another minor issue, reproducible with both Chromium and Google Chrome version 14.0.835.202, see screenshot: http://dl.dropbox.com/u/239841/openb...hromium_14.png
gcc 4.5 release notes say that's possible:
Support for the XOP, FMA4, and LWP instruction sets for the AMD Orochi processors are now available with the -mxop, -mfma4, and -mlwp options.
