Stages

• I. Management of simple arithmetic expressions with constants (3 points)

• II. Type management/verification/conversions (3 points)

• III. Management of global variables (3 points)

• IV. Branching management (3 points)

• V. Management of sub-blocks (3 points)

• VI. Function call management (3 points)

• VII. Type addition (2 points)

Achievements

• Stage 1 : Done. Nothing particular.

• Stage 2 : Done.Nothing particular.

• Stage 3 : Done. Offset processed by ascending in the three. glob_decl_list decl decl_list var_decl vlist are declared as offset_value. Global offsets start at 0, block offsets start at 1 to let the 0 to the block pointer.

• Stage 4 : Done. char* getLabel(int i) and char* getLoop(int i) functions added to return a label with i as an identifier. In use, i is the label/loop counter (which are globals) and the return is a global char* buffer[100] to avoid leak memory. if, elsop and while are declared as label_value. if and while increment the corresponding global counter and elsop collect the label number from if to be accessible to else. The others token which need the label number collect it from one of the three mentioned earlier.

• Stage 5 : Done. Adding of the block pointer use with the global depth / variable depth difference.

• Stage 6 : Done. params is used to note the negative offset of each arg when defining the function. arglist is used to count the number of arguments and ENDCALL(i) the right i. app collects the function type to allow computing with function (e.g. recursive). Globals int arg_count and int arg_type[MAX_ARG] are used to note the arguments number of a function and their types and then, fill them into an attribute. So int arg_count and int type_array[MAX_ARG] are 2 new fields of the attribute structure. This allow the check/conversion type when the function is called.

Usage

make : Compile lang, the myc to pcode compiler. lang takes in input the myc code (./lang < code.c).

./run ExXX (with XX a number) : Compile the XX example from myc to pcode in the ExXX_pcode.c file. The result is also print on the standard output.
