Bitwise logical exclusive-OR
SYNTAX
FUNCTION
DESCRIPTION
r src2 . The result is stored in the destination register, r dest .
modification of the destination register. If the LSB of r guard is 1, r dest is written; otherwise, r dest is not changed.
EXAMPLES
r30 = 0xf310ffff, r40 = 0xffff0000
r10 = 0, r50 = 0x88888888
r20 = 1, r30 = 0xf310ffff,
r50 = 0x88888888
r60 = 0x11119999, r50 = 0x88888888
r70 = 0x55555555, r30 = 0xf310ffff

Initial Values
r src1
operation computes the bitwise, logical exclusive-OR of the first and second arguments, r src1 and
operation optionally takes a guard, specified in r guard . If a guard is present, its LSB controls the
