ARM Diagnostic Directives (Windows CE 5.0)

Send Feedback

The following ARM assembly directives generate diagnostic information.

Directive	Syntax	Description
ASSERT	ASSERT logical-expression	Supports diagnostic generation. If logical-expression returns FALSE, the assembler generates a diagnostic message during the second pass of the assembly. ASSERT can be used inside and outside macros.
!	! arithmetic-expression, string-expression	Related to ASSERT, but is inspected on both passes of the assembly, providing a more flexible means for creating custom error messages. If arithmetic-expression equals 0, the assembler takes no action during pass one, but prints string-expression as a warning during pass two. If arithmetic-expression does not equal 0, the assembler prints string-expression as a diagnostic message. The assembly halts after pass one. This directive is identical to the INFO directive.
INFO	INFO arithmetic-expression, string-expression	If arithmetic-expression equals 0, the assembler takes no action during pass one. It adds source file and line number as a prefix to string-expression, and prints the result as a warning during pass two. If arithmetic-expression does not equal 0, the assembler prints string-expression as a diagnostic message. The assembly halts after pass one. This directive is identical to the ! directive.
