Unknown armasm error

Note: This was originally posted on 21st October 2010 at http://forums.arm.com

I am using RVCT 4.1 build 462, and I have seen this armasm error:

A1903E: Line not seen in first pass; cannot be assembled

Do you have any idea what this means?

Thanks,

I had the very same issue and made the same change to fix the error. This must be an assembler bug. Thanks for the response.

This is caused by armasm becoming stricter about what differences it allows in definitions between it's first and second passes. This is mentioned at [url="http://infocenter.arm.com/help/topic/com.arm.doc.dui0530a/CBAHBCBD.html"]http://infocenter.arm.com/help/topic/com.a...a/CBAHBCBD.html[/url], but it would be good to add the IF :DEF: foo/ELSE example to the notes there.

Hopefully some future armasm will learn to allow it as a special case like the IF :LNOT: :DEF: foo/ENDIF case.

I saw this once when porting some old code that used a lot of defines. Not entirely sure what it means, but I got round it like this

Before:
IF :DEF:MY_DEF ELSE MY_DEF EQU 4 ENDIF

Fix:
IF :LNOT: :DEF: MY_DEF MY_DEF EQU 4 ENDIF
