System for restoring predicate registers via a mask having at least a single bit corresponding to a plurality of registers

A computer-readable medium having stored thereon a plurality of instructions including a first set of instructions for restoring a first register set, said first set of instructions, when executed by a processor, cause said processor to perform the steps comprising of:

• decoding a first instruction that specifies a restoring operation for the register set;
• using a mask to select a plurality of registers of said first register set that are to be restored, said mask includes at least one bit corresponding to a plurality of registers in said first register set;
• and
• restoring the selected plurality of registers of said first register set, including wherein when said one bit is set, the plurality of registers corresponding to said one bit are restored in response to the first instruction.

A computer system operable to restore a first register set comprising of:

• a decoder operable to decode a first instruction specifying a restore operation to be performed on a first register set;
• a restoring device operable to use a mask to select a plurality of registers of said first register set that are to be restored, said mask includes at least one bit corresponding to a plurality of registers in said first register set;
• and
• the restoring device further operable to restore the selected plurality of registers, including wherein when said one bit is set, the plurality of registers corresponding to said one bit are restored in response to the first instruction.
