* config/tc-arm.c (do_iwmmxt_wldstd): Correct the offset range for
WLDRD/WSTRD instruction.
2005-08-03 Nick Clifton <nickc@redhat.com>
* gas/arm/iwmmxt-bad2.s: New file: Check for error messages about
erroneous offsets in iwmmxt instructions. Cannot be part of
iwmmxt-bad.s because the errors there stop the assembler before it
gets to check the offsets in instructions.
* gas/arm/iwmmxt-bad2.d: New file.
* gas/arm/iwmmxt-bad2.l: New file: Expected error messages.
2005-08-02 Khem Raj <kraj@mvista.com>
* gas/arm/iwmmxt.s: Change the offset values of the WLDRD, WSTRD
and WSTRW instructions to be larger than +/-255.
* gas/arm/iwmmxt.d: Fix the expected results for these
instructions.
