fneqflags
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. If
an argument is denormalized, zero is substituted before computing the comparison, and the IFZ 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.
