+       tmp-hack,tmp-m32-hack,tmp-m16-hack,tmp-itable-hack,
+       tmp-run-hack) : New.
+       * configure.in (mips64vr4xxx): Switch to using the HACK
+       generator.  Set TARGET_ENABLE_FR.

+       DSLL,DSRL,DSRA,DSLLV,DSRAV,DMULT,DMULTU,DDIV,DDIVU,JALX32,JALX): 
+       Drop the "64" qualifier to get the HACK generator working.
+       Use IMMEDIATE rather than IMMED.  Use SHAMT rather than SHIFT.
+       Add vr4121 where necessary.
+       * mips.igen (do_daddiu,do_ddiv,do_divu): Remove the 64-only
+       qualifier to get the hack generator working.
+       (do_dsll,do_dsllv,do_dsra,do_dsrl,do_dsrlv): New.
+       (DSLL): Use do_dsll.
+       (DSLLV): Use do_dsllv.
+       (DSRA): Use do_dsra.
+       (DSRL): Use do_dsrl.
+       (DSRLV): Use do_dsrlv.
+       (BC1): Move *vr4100,*vr4111, and *vr4121 to get the HACK 
+       generator working.
+       (CxC1, DMxC1, MxC1,MACCU,MACCHI,MACCHIU): Rename to 
+       get the HACK generator working.
+       * vr.igen: Add *vr4320 where missing.
+       (MACC) Rename to get the HACK generator working.
