Subject: [PATCH 2/3] sparc: Change software trap amd mov handling

Hi all,

Please find attached a patch to change the software trap and mov instruction handling into line with the V8 SPARC Architecture Manual.

wr instructions are also updated to match the changes to the mov instructions.

The V8 manual has an extra software_tarp# mode not handled by gas:
 imm7 + regrs1

Synthetic instruction changes:
 GAS uses 'wr regrs1, %g0, regrd' and 'wr %g0, imm, regrd'
 for 'mov imm_reg, regrd'.
 The V8 manual uses 'wr %g0, imm_regrs2, regrd'
 for 'mov imm_reg, regrd'.
Change the behaviour to match the V8 manual.

Regards
	Mark Fortescue.

PS: Sorry the patch is attached. My mail client mangles in-text patches.
