/* CAYMAN notes
49
Why CAYMAN got loops for lots of instructions is explained here.
50
51
-These 8xx t-slot only ops are implemented in all vector slots.
52
MUL_LIT, FLT_TO_UINT, INT_TO_FLT, UINT_TO_FLT
53
These 8xx t-slot only opcodes become vector ops, with all four
54
slots expecting the arguments on sources a and b. Result is
55
broadcast to all channels.
56
MULLO_INT, MULHI_INT, MULLO_UINT, MULHI_UINT, MUL_64
57
These 8xx t-slot only opcodes become vector ops in the z, y, and
58
x slots.
59
EXP_IEEE, LOG_IEEE/CLAMPED, RECIP_IEEE/CLAMPED/FF/INT/UINT/_64/CLAMPED_64
60
RECIPSQRT_IEEE/CLAMPED/FF/_64/CLAMPED_64
61
SQRT_IEEE/_64
62
SIN/COS
63
The w slot may have an independent co-issued operation, or if the
64
result is required to be in the w slot, the opcode above may be
65
issued in the w slot as well.
66
The compiler must issue the source argument to slots z, y, and x
