PCC Implementation by Leopold Toetsch
Functions
static Instruction *insINS(PARROT_INTERP, IMC_Unit *unit, NOTNULL(Instruction *ins), char *name, SymReg **regs, int n)- Utility instruction routine. Creates and inserts an instruction into the current block in one call.
SymReg *get_pasm_reg(PARROT_INTERP, const char *name)- get or create the SymReg
SymReg *get_const(PARROT_INTERP, const char *name, int type)- get or create a constant
static Instruction *pcc_get_args(PARROT_INTERP, IMC_Unit *unit, NOTNULL(Instruction *ins), char *op_name, int n, SymReg **args, 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), 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))- TODO: Not yet documented!!!
static Instruction *move_regs(PARROT_INTERP, IMC_Unit *unit, NOTNULL(Instruction *ins), int n, SymReg **dest, SymReg **src)- TODO: 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))- TODO: 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
