PR target/44626
Backport from mainline:
2009-06-22 Nathan Sidwell <nathan@codesourcery.com>
* config/arm/arm.c (arm_print_operand): Deal with HIGH.
* config/arm/constraints.md (j): New constraint for movw operands.
(N): Remove thumb2 meaning.
* config/arm/arm.md (*arm_movw): Delete.
(*arm_movsi_insn): Use j constraint for movw instead of N constraint.
* config/arm/vfp.md (*arm_movsi_vfp, *thumb2_movsi_vfp): Likewise.
* config/arm/thumb2.md (*thumb2_movsi_insn): Likewise.
