12.3.40 A2334:Only Labels Defined in the Current Assembly Unit
Can Be Referenced in an EQU Expression
Type: Error
Description: One of the symbols specified in an EQU expression is an
external symbol, which was previously specified in an XREF
directive. This is not alloweddue to a limitation in the ELF file
format.
Example:
XREF label
CstSec: SECTION
lab: DC.B 6
...
equLabel: EQU label+6
...
Tip: An EQU label containing a reference to an object must be
defined in the same assembly module as the object they refer
to. Then the EQU label can be exported to other modules in the
application.
Example:
XDEF label, equlabel
...
CstSec: SECTION
lab: DC.B 6
label: DC.W 6
...
equLabel: EQU label+6
...
