Using CW for ColdFire v.6.4, target MCF5307, assembly error: "Illegal relocatable".

Veter — Fri, 06 Jul 2007 02:43:43 GMT

I have this simple statement in my os_cpu_a.s file:

...

TER0 .equ ___MBAR+0x151

...

It seems quite legal but compiler throws exception bellow:

Error : Illegal relocatable expression
os_cpu_a.s line 161 TER0 .equ ___MBAR+0x151

I'm quite sure the answer is very simple I just can't find any info in the help files.

Can anyone please give me a hint what I'm I missing here?

The CodeWarrior assembler only supports equates which can be fully resolved at assembly time. I think that a lot of assemblers work this way.

You can achieve the effect that you want by using a .textequ directive:

TER0: .textequ "___MBAR+0x151"

When the assembler encounters the symbol TER0 in the source code, it will substitute the string __MBAR+0x151 (Like #define in the C preprocessor).

Hope this helps
