Thanks for the info.

Since the gcc does produce thumb code for -mthumb option AND the assembler
'gas' does not recognize the thumb code except being told
explicitely(through
-mthumb option), I would think that there is a problem with the assembler
was
built and *not with the gcc*. Don't you think so ? 

The assembler is built from the binutils-2.10 package. I built the 'gas'
binary though a separate make(not part of the gcc make). And since there
was not target for arm-wrs-vxworks, I created a new target 'arm-wrs-vxworks'
with the same properties as 'arm-coff' target and built the binutils
package.
May be the new target was not created properly, though I did it carefully. 

There is a target in binutils package called *-*-vxworks. But it is for aout
format and i wanted a coff format. So I could not use it. 

May be a new target called 'arm-wrs-vxworks' shoould be added to the
binutils 
package with the proper settings.

Yes, there a define for ARM_APP_OFF which a test for THUMB targets. And I
think
it is working fine(with the above reasoning).
