[Libre-soc-dev] [RFC] REMAP, SHAPE, complex (full) FFT

[Luke Kenneth Casson Leighton]

https://git.libre-soc.org/?p=openpower-isa.git;a=blob;f=src/openpower/decoder/isa/test_caller_svp64_dct.py;hb=HEAD

created the yield/schedule DCT variant yesterday, now have both an
inner and outer butterfly unit test.

required adding a special twin DCT mul-add instruction which is
different from the FFT mul-add.

joining the two together should be easy: my next concern is how to
easily generate the cosine table, although this is only needed for a
Vertical-First variant which i will get to in a couple of days.
