- Fixed immediate source operand of LDEXP, LD[IL][FD]
which is an integer, unlike several other FPP instructions.
- Renamed floating point instruction formats so they match the
instruction descriptions in the architecture handbook better.
I haven't done much compatibility testing with MACRO11 to check
weirdnesses, but the original functionality is very limied: none
of the mnemonics has operands.
which have an general (source) argument and an AC destination.
There are no FPP instrs which have 1 general source arg;
only with 1 general destination (even TSTF).
