* Don't call ccmmc_register_alloc() after saving registers for write functionHW6Ting-Wei Lan2016-01-211-4/+8

* Save arguments before calling any functionTing-Wei Lan2016-01-201-16/+20
| | | | | We should not skip the argument-saving step for functions without arguments of the special write function.
* Support calling functions with argumentsTing-Wei Lan2016-01-201-29/+217
| | | | | | | | | | | 1. The symbol attribute is modified to allow storing a related register instead of a memory location. 2. Call check_relop_expr() on all scalar function arguments to make sure that type information is available when generating code. 3. calc_array_offset() is modified to accept incomplete arrays, which is used when passing parts of arrays as arguments. 4. It is currently possible to crash the code generator by calling a function with more than 3 arguments.
