[Bug other/14708] description of -ffloat-store in gcc man page incorrect/inaccurate
------- Additional Comments From pinskia at gcc dot gnu dot org 2004-03-24 06:36 -------
Looks fixed on the mainline:
Do not store floating point variables in registers, and inhibit other options that might change whether a
floating point value is taken from a register or memory.
This option prevents undesirable excess precision on machines such as the 68000 where the floating
registers (of the 68881) keep more precision than a double is supposed to have. Similarly for the x86
architecture. For most programs, the excess precision does only good, but a few programs rely on the
precise definition of IEEE floating point. Use -ffloat-store for such programs, after modifying them to
store all pertinent intermediate computations into variables.
Is this enough or is there more?
