* x86: Use consistent 3dnowext function and macro name suffixesDiego Biurrun2012-08-03
| | | | | | Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to "3dnowext", which is a more common name of the CPU flag, as reported e.g. by the Linux kernel, unifies this.
* fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64.Ronald S. Bultje2012-07-31
| | | | | 64-bit CPUs always have SSE available, thus there is no need to compile in the 3dnow functions. This results in smaller binaries.
