MIPS/gas: Reject $0 as source register for DAUI instruction
The MIPS64R6 TRM requires that the source register for DAUI not be r0. [1] "MIPS Architecture for Programmers Volume II-A: The MIPS64 Instruction Set Manual", Imagination Technologies Ltd., Document Number: MD00087, Revision 6.06, December 15, 2016, Section 3.2 "Alphabetical List of Instructions", pp. 67-68. gas/ * testsuite/gas/mips/r6-branch-constraints.s: Rename to ... * testsuite/gas/mips/r6-reg-constraints.s: this and add test case for DAUI. * testsuite/gas/mips/r6-branch-constraints.l: Rename to ... * testsuite/gas/mips/r6-reg-constraints.l: this and add test for DAUI. * testsuite/gas/mips/mips.exp: Rename test from r6-branch-constraints to r6-reg-constraints. opcodes/ * mips-opc.c (mips_builtin_opcodes): Change source register constraint for DAUI.
