* Choose, from the list of all the possible datatypes each expression may take, the single datatype that it will in fact take. |
|
43 |
* The resulting (chosen) datatype, will be stored in the symbol_c.datatype variable, leaving the candidate datatype list untouched! |
|
44 |
* |
|
45 |
* For rvalue expressions, this decision will be based on the datatype of the lvalue expression. |
|
46 |
* For lvalue expressions, the candidate datatype list should have a single entry. |
|
47 |
* |
|
48 |
* For example, the very simple literal '0' in 'foo := 0', may represent a: |
|
49 |
* BOOL, BYTE, WORD, DWORD, LWORD, USINT, SINT, UINT, INT, UDINT, DINT, ULINT, LINT (as well as the SAFE versions of these data tyes too!) |
|
50 |
* |
|
51 |
* In this class, the datatype of '0' will be set to the same datatype as the 'foo' variable. |
|
52 |
* If the intersection of the candidate datatype lists of the left and right side expressions is empty, |
|
53 |
* then a datatype error has been found, and the datatype is either left at NULL, or set to a pointer of an invalid_type_name_c object! |
