// Track 1: Core Infrastructure & Basic Expressions

// * Create intermediate_code.h/.c defining the instruction structure:
|
|
// - Struct with fields for: opcode, result, operand1, operand2, label
|
|
// - Enum for all operation types (ADD, SUB, MUL, DIV, etc.)
|
|
// * Implement temp variable generator function that produces unique names (t1, t2, etc.)
|
|
// * Create specific code emission functions:
|
|
// - emit_binary_op(char* result, char* op, char* arg1, char* arg2)
|
|
// - emit_unary_op(char* result, char* op, char* arg)
|
|
// - emit_assignment(char* target, char* source)
|
|
// * Add Bison actions for arithmetic expressions:
|
|
// - Addition: $$ = new_temp(); emit_binary_op($$, "ADD", $1, $3);
|
|
// - Subtraction, multiplication, division, modulo
|
