SYNTAX
FUNCTION
DESCRIPTION
value of rsrc1 and writes a bit vector representing the exception flags into rdest. The argument value is in IEEE single-
precision floating-point format; the result is an integer bit vector. The bit vector stored in rdest has the same format as
the IEEE exception bits in the PCSW. The exception flags in PCSW are left unchanged by this operation. If rsrc1 is
denormalized, the IFZ bit in the result is set.
the modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
