IEEE Std 754-1985 Requirements for
SPARC V9
The IEEE Std 754-1985 floating-point standard contains a number of implementation
dependencies.
Please see Appendix B of Commonality for choices for these implementation
dependencies, to ensure that SPARC V9 implementations are as consistent as
possible.
Following is information specific to the SPARC64 V implementation of SPARC V9 in
these sections:
■
Traps Inhibiting Results on page 61
■ Floating-Point Nonstandard Mode on page 61
B.1 Traps Inhibiting Results
Please refer to Section B.1 of Commonality.
The SPARC64 V hardware, in conjunction with kernel or emulation code, produces
the results described in this section.
B.6 Floating-Point Nonstandard Mode
In this section, the hardware boundary conditions for the unfinished_FPop exception
and the nonstandard mode of SPARC64 V floating-point hardware are discussed.
