DESCRIPTION
ParserUtil - Parser support functions.
Functions
PARROT_CAN_RETURN_NULL Instruction *iNEW(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(SymReg *r0), NOTNULL(char *type), NULLOK(SymReg *init), int emit)void op_fullname(NOTNULL(char *dest), NOTNULL(const char *name), NOTNULL(SymReg *args[]), int narg, int keyvec)- Lookup the full opcode given the short name
- Obviously the registers must be examined before returning the correct opcode.
- NOTE: All this nasty IMC_TRACE is for tracking down equally nasty bugs, so if you don't like the looks of it, stay out, but please don't remove it. :) -Mel
PARROT_WARN_UNUSED_RESULT int check_op(PARROT_INTERP, NOTNULL(char *fullname), NOTNULL(const char *name), NOTNULL(SymReg *r[]), int narg, int keyvec)- Return opcode value for op name
PARROT_WARN_UNUSED_RESULT PARROT_CAN_RETURN_NULL static Instruction *maybe_builtin(PARROT_INTERP, NOTNULL(const char *name), NOTNULL(SymReg **r), int n)- TODO: Needs to be documented!!!
PARROT_WARN_UNUSED_RESULT int is_op(PARROT_INTERP, NOTNULL(const char *name))- Is instruction a parrot opcode?
PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL static const char *to_infix(PARROT_INTERP, NOTNULL(const char *name), NOTNULL(SymReg **r), NOTNULL(int *n), int mmd_op)- sub x, y, z => infix .MMD_SUBTRACT, x, y, z

PARROT_CAN_RETURN_NULL Instruction *INS(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(const char *name), NULLOK(const char *fmt), NOTNULL(SymReg **r), int n, int keyvec, int emit)- Make an instruction.
- name ... op name fmt ... optional format regs ... SymReg ** n ... # of params keyvec ... s. KEY_BIT() emit ... if true, append to instructions
- s. e.g. imc.c for usage

* P = new type, [init]
* PASM like:
* new P, .SomeThing
* is done in the lexer, this is a mess
* best would be to have a flag in core.ops, where a PMC type is expected
set I0, 5 -> set_i_ic
set I0, I1 -> set_i_i
