Cutting Constant warning Codewarrior IDE 5.7, programming 9S12XDP512 in assembly

zdriver — Tue, 26 Jun 2007 02:11:24 GMT

Hello,

The assembler returns this warning, although it assembles the code properly and the code works fine. Is there a different syntax to use on my assembler line or other solution to eliminate this warning ? I am new to Codewarrior, so any suggestion is welcome. The warning looks like this;

Warning : A1415: Cutting constant: Value -47424 is not in range [-32768...65535]

The tip in help is to use a larger field? How do I do this?

The line of code that causes this warning, this is from the list file;

a00CC10 05FB 46C0 JMP [CHANNEL_PATH,PCR]

From the list file, I have defined CHANNEL_PATH in ram, it is 16 bit, located at $12D4

0000 12D4 CHANNEL_PATH EQU 724 + RAMSTART

Hello

I am unable to reproduce the issue here on CodeWarrior for HCS12 V4.6.

You need to either submit a service request for that or send me some source file reproducing the issue.

That warning only occurs in the absolute assemble mode.
The code is correct, so I would think in this case the assembler should be adapted. Anyway
you can use a PC relative JMP instead and do the cutting explicitly, like this:

JMP [$FFFF & (CHANNEL_PATH - Next),PC]
Next:

That generates the same code but it avoids the warning.
