SYNTAX
FUNCTION
DESCRIPTION
rsrc1 rsrc2 and stores a bit vector representing the exception flags into rdest. The argument values are 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.
Rounding is according to the IEEE rounding mode bits in PCSW. If an argument is denormalized, zero is substituted
before computing the product, and the IFZ bit in the result is set. If the product would be denormalized, the OFZ bit in
the result is set.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
