particular opcode in order for an instruction to be an instance
of that opcode.
- The args component is a string containing one character
- for each operand of the instruction.
+ The args component is a string containing one character for each operand of
+ the instruction. Characters used as a prefix allow any second character to
+ be used without conflicting with the main operand characters.
Bit positions in this description follow HP usage of lsb = 31,
"at" is lsb of field.
In the args field, the following characters are unused:
- ' "#$% *+- ./ :; '
- ' [\] '
- ' { } '
+ ' !"#$%& *+- ./ :;< > @'
+ ' M U [\] '
+ 'a d {|}~'
Here are all the characters:
c indexed load completer.
C short load and store completer.
Y Store Bytes Short completer
- < non-negated compare/subtract conditions.
- a compare/subtract conditions
- d non-negated add conditions
- & logical instruction conditions
- U unit instruction conditions
- > shift/extract/deposit conditions.
- ~ bvb,bb conditions
V 5 bit immediate value at 31
i 11 bit immediate value at 31
j 14 bit immediate value at 31
W 17 bit branch displacement (PC relative)
z 17 bit branch displacement (just a number, not an address)
+Condition operands all have '?' as the prefix:
+
+ ?f Floating point compare conditions (encoded as 5 bits at 31)
+
+ ?a add conditions
+ ?d non-negated add branch conditions
+ ?@ add branch conditions followed by nullify
+
+ ?s compare/subtract conditions
+ ?t non-negated compare conditions
+ ?n compare conditions followed by nullify
+
+ ?l logical conditions
+ ?b branch on bit conditions
+
+ ?x shift/extract/deposit conditions
+ ?y shift/extract/deposit conditions followed by nullify for conditional
+ branches
+
+ ?u unit conditions
+
Also these:
p 5 bit shift count at 26 (to support the SHD instruction) encoded as
I Source Floating Point Operand Format Completer encoded 1 bits at 20
(for 0xe format FP instructions)
G Destination Floating Point Operand Format Completer encoded 2 bits at 18
- M Floating-Point Compare Conditions (encoded as 5 bits at 31)
- ? non-negated/negated compare/subtract conditions.
- @ non-negated/negated add conditions.
- ! non-negated add conditions.
s 2 bit space specifier at 17.
b register field at 10.
Q 5 bit immediate value at 10 (a bit position specified in
the bb instruction. It's the same as r above, except the
value is in a different location)
- | shift/extract/deposit conditions when used in a conditional branch
And these (PJH) for PA-89 F.P. registers and instructions:
8 5 bit register field at 20 (used in 'fmpyadd' and 'fmpysub')
9 5 bit register field at 25 (used in 'fmpyadd' and 'fmpysub')
H Floating Point Operand Format at 26 for 'fmpyadd' and 'fmpysub'
