[ECOS] Assembler errors for 603e

[ECOS] Assembler errors for 603e

[Suresh N]

Hi all,

	I am trying to port the 860 code to 8260 code... 
	I am using the same tools for building it....

	(1) The offsets in the case of 8260 starts from 65k from IMMR.. 
	so i get the error in the assembler as 
 
<cut>

/export/home1/nsuresh/ecos-1.3.1/packages/hal/powerpc/ads/v1_3_1/src/ads.S:125: Error: operand
out of range (65536 not between -32768 and 32767)

</cut>

	how i can change the range....

	(2) the assembler is not recognising the andi opcode.. any idea
why?
	
<cut>

/export/home1/nsuresh/ecos-1.3.1/packages/hal/powerpc/ads/v1_3_1/src/ads.S:89: Error: Unrecognized
opcode: `andi'

/export/home1/nsuresh/ecos-1.3.1/packages/hal/powerpc/ads/v1_3_1/src/ads.S:107: Error: Unrecognized

</cut>

	thanx in advance...	
	bye

Rewrite the code to use 32 bit offsets.

Yes, there is no such thing as an andi instruction. Try 'andi.'
instead, but beware that it changes the CC.

I didn't say 'reduce the offset', I said:

>>  Rewrite the code to use 32 bit offsets.

Instead of 
  lwz rn,offset(rx)

use
  lwzx rn,rx,ry

where ry contains the offset.
