34.2.5.4 CLZ
Count Leading Zeros.
CLZ{cond} Rd, Rm
where:
cond is an optional condition code, see
Rd is the destination register.
Rm is the operand register.
The CLZ instruction counts the number of leading zeros in the value in Rm and returns the
result in Rd. The result value is 32 if no bits are set in the source register, and zero if
bit[31] is set.
Do not use SP and do not use PC.
This instruction does not change the flags.
