-/* The i386 floating point hardware (the 387 compatible FPU, not the modern
- SSE/SSE2 hardware) has a controllable rounding precision. It is specified
- through the 'PC' bits in the FPU control word ('fctrl' register). (See
- the GNU libc i386 <fpu_control.h> header for details.)
-
- On some platforms, such as Linux or Solaris, the default precision setting
- is set to "extended precision". This means that 'long double' instructions
- operate correctly, but 'double' computations often produce slightly
- different results as on strictly IEEE 754 conforming systems.
-
- On some platforms, such as NetBSD, the default precision is set to
- "double precision". This means that 'long double' instructions will operate
- only as 'double', i.e. lead wrong results.
-
- The FPU control word is under control of the application, i.e. it is
- not required to be set either way by the ABI. (In fact, the i386 ABI
- http://refspecs.freestandards.org/elf/abi386-4.pdf page 3-12 = page 38
- is not clear about it. But in any case, gcc treats the control word
- like a "preserved" register: it emits code that assumes that the control
- word is preserved across calls, and it restores the control word at the
- end of functions that modify it.)
-
- See Vincent Lefèvre's page http://www.vinc17.org/research/extended.en.html
- for a good explanation.
- See http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html for
- some argumentation which setting should be the default. */
