5 """SVP64 OpenPOWER v3.0B assembly translator
7 This class takes raw svp64 assembly mnemonics (aliases excluded) and creates
8 an EXT001-encoded "svp64 prefix" (as a .long) followed by a v3.0B opcode.
10 It is very simple and straightforward, the only weirdness being the
11 extraction of the register information and conversion to v3.0B numbering.
13 Encoding format of svp64: https://libre-soc.org/openpower/sv/svp64/
14 Encoding format of arithmetic: https://libre-soc.org/openpower/sv/normal/
15 Encoding format of LDST: https://libre-soc.org/openpower/sv/ldst/
16 **TODO format of branches: https://libre-soc.org/openpower/sv/branches/**
17 **TODO format of CRs: https://libre-soc.org/openpower/sv/cr_ops/**
