* avcodec/x86/fft: Remove obsolete 3dnow functionsAndreas Rheinhardt2022-06-22
| | | | | | | | | | | x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT, SSE and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2). So given that the only systems which benefit from the 3dnow implementations are truely ancient 32bit AMD x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| * 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.
