compilers/imcc/parser_util.c

DESCRIPTION ^

ParserUtil - Parser support functions.

Functions ^

Instruction *iNEW
 * 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
void op_fullname
Lookup the full opcode given the short name 
   set I0, 5  -> set_i_ic
   set I0, I1 -> set_i_i
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
int check_op
Return opcode value for op name
int is_op
Is instruction a parrot opcode?
static Instruction *var_arg_ins
TODO: Needs to be documented!!!
Instruction *INS
Makes an instruction.name ... op name fmt ... optional format regs ... SymReg ** n ... number of params keyvec ... see KEY_BIT() emit ... if true, append to instructionssee imc.c for usage
int do_yylex_init
TODO: Needs to be documented!!!
PMC *imcc_compile
Compile a pasm or imcc stringFIXME as we have separate constants, the old constants in ghash must be deleted.
PMC *imcc_compile_pasm
TODO: Needs to be documented!!! 
 * Note: This function is provided for backward compatibility. This
 * function can go away in future.
PMC *imcc_compile_pir
TODO: Needs to be documented!!! 
 * Note: This function is provided for backward compatibility. This
 * function can go away in future.
PMC *IMCC_compile_pir_s
TODO: Needs to be documented!!!
PMC *IMCC_compile_pasm_s
TODO: Needs to be documented!!!
PMC *imcc_compile_pasm_ex
TODO: Needs to be documented!!!
PMC *imcc_compile_pir_ex
TODO: Needs to be documented!!!
static void *imcc_compile_file
Compile a file by filename (can be either PASM or IMCC code)
void *IMCC_compile_file
TODO: Needs to be documented!!! 
 * Note: This function is provided for backward compatibility. This
 * function can go away in future.
void *IMCC_compile_file_s
TODO: Needs to be documented!!!
void register_compilers
Register additional compilers with the interpreter
static int change_op
TODO: Needs to be documented!!!
int try_find_op
Try to find valid op doing the same operation e.g. 
   add_n_i_n  => add_n_n_i
   div_n_ic_n => div_n_nc_n
   div_n_i_n  => set_n_i ; div_n_n_n
   ge_n_ic_ic => ge_n_nc_ic
   acos_n_i   => acos_n_n
static const char *try_rev_cmp
TODO: Needs to be documented!!!
int imcc_vfprintf
Formats a given series of arguments per a given format string and prints it to the given Parrot IO PMC.
void imcc_init
TODO: Needs to be documented!!!
static void imcc_destroy_macro_values
A callback for parrot_chash_destroy_values() to free all macro-allocated memory.
void imcc_destroy
TODO: Needs to be documented!!!
