revert commits improved performance of some extensible Standard Functions (ADD, MUL, AND, OR, XOR)
Following commits are reverted:
mjsousa 0b275a2 improve performance of some extensible Standard Functions (ADD, MUL, AND, OR, XOR) -- increase hardcoded limit to 499
mjsousa 2228799 improve performance of some extensible Standard Functions (ADD, MUL, AND, OR, XOR) -- Add comments!!
mjsousa ce81fa6 improve performance of some extensible Standard Functions (ADD, MUL, AND, OR, XOR)"
The reason is that they cause regression in some cases (if function is
used as argument for function block, for example) and this is not
fixed for a long time.
(* Test whether the keyword XXXX may be used as an identifier for:
* IL label name/identifier
*
* The XXXX names in the following code are merely a placeholder.
* They will be replaced by several identifiers before actual testing
* of the compiler.
*)
(* The identifiers that will replace the XXXX
* must be placed on a line starting with #
* All identifiers preceded by # are ignored!
* The identifier list must be placed inside an IEC 61131-3 comment.

* in IL code. In ther words, in IL code we cannot use
* identifiers identical to IL operators to identify variables,
* functions, etc...
* Identifiers identical to IL operators are therefore
