Functions
PARROT_WARN_UNUSED_RESULT PARROT_CAN_RETURN_NULL static Instruction *insINS(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(Instruction *ins), ARGIN(const char *name), NOTNULL(SymReg **regs), int n)- Utility instruction routine. Creates and inserts an instruction into the current block in one call.
PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL SymReg *get_pasm_reg(PARROT_INTERP, ARGIN(const char *name))- get or create the SymReg
PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL SymReg *get_const(PARROT_INTERP, ARGIN(const char *name), int type)- get or create a constant
PARROT_WARN_UNUSED_RESULT PARROT_CAN_RETURN_NULL static Instruction *pcc_get_args(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(Instruction *ins), ARGIN(const char *op_name), int n, NULLOK(SymReg **args), ARGIN_NULLOK(const int *arg_flags))- set arguments or return values get params or results used by expand_pcc_sub_call and expand_pcc_sub
static void unshift_self(NOTNULL(SymReg *sub), NOTNULL(SymReg *obj))- prepend the object to args or self to params
void expand_pcc_sub(PARROT_INTERP, NOTNULL(NOTNULL(IMC_Unit *unit)), NOTNULL(NOTNULL(Instruction *ins)))- Expand a PCC (Parrot Calling Convention) subroutine by generating the appropriate prologue and epilogue for parameter passing/returning.
void expand_pcc_sub_ret(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(Instruction *ins))- Expand a PCC sub return directive into its PASM instructions
static int pcc_reg_mov(PARROT_INTERP, unsigned char d, unsigned char s, NOTNULL(void *vinfo))- RT#48260: Not yet documented!!!
PARROT_WARN_UNUSED_RESULT PARROT_CANNOT_RETURN_NULL static Instruction *move_regs(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(Instruction *ins), int n, NOTNULL(SymReg **dest), NOTNULL(SymReg **src))- RT#48260: Not yet documented!!!
static int recursive_tail_call(PARROT_INTERP, NOTNULL(NOTNULL(IMC_Unit *unit)), NOTNULL(NOTNULL(Instruction *ins)), NOTNULL(SymReg *sub))- convert a recursive tailcall into a loop
static void insert_tail_call(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(NOTNULL(Instruction *ins)), NOTNULL(SymReg *sub), NULLOK(SymReg *meth))- RT#48260: Not yet documented!!!
void expand_pcc_sub_call(PARROT_INTERP, NOTNULL(IMC_Unit *unit), NOTNULL(Instruction *ins))- Expand a PCC subroutine call (IMC) into its PASM instructions This is the nuts and bolts of pdd03 routine call style
