CLREX

Clear-Exclusive clears the local monitor of the executing PE.

It has encodings from the following instruction sets: A32 ( A1 ) and T32 ( T1 ) .

A1

111101010111(1)(1)(1)(1)(1)(1)(1)(1)(0)(0)(0)(0)0001(1)(1)(1)(1)

Encoding for the A1 variant

CLREX{<c>}{<q>}

Decode for this encoding

// No additional decoding required

T1

Encoding for the T1 variant

CLREX{<c>}{<q>}

Decode for this encoding

// No additional decoding required
