Instructions are provided to test individual CR bits.
3.7.4.1
In most integer instructions, when the CR is set to reflect the result of the operation (that is, when Rc = 1),
and for addic., andi., and andis., the first three bits of CR0 are set by an algebraic comparison of the result
to zero; the fourth bit of CR0 is copied from XER[SO]. For integer instructions, CR0[0:3] are set to reflect
the result as a signed quantity. The EQ bit reflects the result as an unsigned quantity or bit string.
The CR0 bits are interpreted as shown in
into the destination register) is undefined, the value placed in the first three bits of CR0 is undefined.
3.7.4.2
In all floating-point instructions when the CR is set to reflect the result of the operation (that is, when Rc
= 1), the CR1 field (bits 4 to 7 of the CR) is copied from FPSCR[0:3] to indicate the floating-point
exception status. For more information about the FPSCR, see
Control Register
3.7.4.3
When a specified CR field is set by a compare instruction, the bits of the specified field are interpreted as
shown in
instructions.

Condition Register CR0 Field Definition
Negative (LT). This bit is set when the result is negative.
Positive (GT). This bit is set when the result is positive (and not zero).
Zero (EQ). This bit is set when the result is zero.
Summary overflow (SO). This is a copy of the final state of XER[SO] at the completion of the instruction.
