.eqv (and ==) ought not simplify expressions involving dot or other
symbols set by .eqv. If such simplification occurs, the value of dot
will be that at the assignment rather than at the place where the
symbol is used.
PR 23800
* expr.c (expr): Don't simplify expressions involving forward_ref
symbols when mode is expr_defer.
* config/tc-spu.c (spu_cons): Parse expression using normal
expression evaluation if @ppu is not detected.
* testsuite/gas/all/eqv-dot.d,
* testsuite/gas/all/eqv-dot.s: New test.
* testsuite/gas/all/gas.exp: Run it.
The field in spu_opcode is unsigned, and for some values of opcode we can end
up shifting into the high bit. So avoid possibly creating a negative number
and then assigning it to a unsigned field by shifting an unsigned constant.
