- * The opcode table 'votstrs' needs to be sorted on opcode frequency.
- * That is, AFTER we hash it with hash_...(), we want most-used opcodes
- * to come out of the hash table faster.
- *
- * I am sorry to inflict yet another VAX assembler on the world, but
- * RMS says we must do everything from scratch, to prevent pin-heads

- * This is a vaguely modular set of routines in C to parse VAX
- * assembly code using DEC mnemonics. It is NOT un*x specific.
- *
- * The idea here is that the assembler has taken care of all:
- * labels
- * macros
- * listing
- * pseudo-ops
- * line continuation
- * comments
- * condensing any whitespace down to exactly one space
- * and all we have to do is parse 1 line into a vax instruction
- * partially formed. We will accept a line, and deliver:
- * an error message (hopefully empty)
- * a skeleton VAX instruction (tree structure)
- * textual pointers to all the operand expressions
- * a warning message that notes a silly operand (hopefully empty)

- * 17may86 Dean Elsner. Bug if line ends immediately after opcode.
- * 30apr86 Dean Elsner. New vip_op() uses arg block so change call.
- * 6jan86 Dean Elsner. Crock vip_begin() to call vip_op_defaults().
- * 2jan86 Dean Elsner. Invent synthetic opcodes.
- * Widen vax_opcodeT to 32 bits. Use a bit for VIT_OPCODE_SYNTHETIC,
- * which means this is not a real opcode, it is like a macro; it will
- * be relax()ed into 1 or more instructions.
- * Use another bit for VIT_OPCODE_SPECIAL if the op-code is not optimised
- * like a regular branch instruction. Option added to vip_begin():
- * exclude synthetic opcodes. Invent synthetic_votstrs[].
- * 31dec85 Dean Elsner. Invent vit_opcode_nbytes.
- * Also make vit_opcode into a char[]. We now have n-byte vax opcodes,
- * so caller's don't have to know the difference between a 1-byte & a
- * 2-byte op-code. Still need vax_opcodeT concept, so we know how
- * big an object must be to hold an op.code.
- * 30dec85 Dean Elsner. Widen typedef vax_opcodeT in "vax-inst.h"
- * because vax opcodes may be 16 bits. Our crufty C compiler was
- * happily initialising 8-bit vot_codes with 16-bit numbers!
- * (Wouldn't the 'phone company like to compress data so easily!)
- * 29dec85 Dean Elsner. New static table vax_operand_width_size[].
- * Invented so we know hw many bytes a "I^#42" needs in its immediate
- * operand. Revised struct vop in "vax-inst.h": explicitly include
- * byte length of each operand, and it's letter-code datum type.
- * 17nov85 Dean Elsner. Name Change.
- * Due to ar(1) truncating names, we learned the hard way that
- * "vax-inst-parse.c" -> "vax-inst-parse." dropping the "o" off
- * the archived object name. SO... we shortened the name of this
- * source file, and changed the makefile.

/* Parse a vax operand in DEC assembler notation.
For speed, expect a string of whitespace to be reduced to a single ' '.
This is the case for GNU AS, and is easy for other DEC-compatible
