MKSOFTFLOAT=yes). The main purpose of this feature is to let NetBSD work
in machines with the 68040LC chip (those that have the FPU bug).
All the work has been done by Bruce O'Neel <edoneel AT sdf.lonestar.org>,
with some very minor changes by me; the patches were being posted to the
port-mac68k mailing list. It has been tested for a long time by several
users, including me.
I have just verified that regular releases, as well as soft-float ones,
continue to build.
There have been no objections to this patch since I asked for them in July
in the port-mac68k list.
version into different directories. Which version a given port uses is
controlled by the SOFTFLOAT_BITS make variable. This is set to 64 (which
uses the same code we had before) by default. 32-bit platforms that don't
need extended precision support might get better performance by using 32.
Set the ARM port to use the 32-bit version of SoftFloat, since this is more
than a factor of two faster than the 64-bit version. This should get the
floating-point performance back to what it was in 1.5.
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.
if we actually need them for 80/128-bit support.
I'm not sure this is Right, but I suspect the #ifdefs around here need
revising to handle sparc64 nicely anyway. Still, it compiles on ARM again
now.
but not in EGCS.
This version of fixunssfsi is almost exactly the arm32 version. fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.
Only minimal testing has been applied so far.
mostly-MI floating-point implementation for use by gcc -msoft-float.
It's currently only used by arm26, but should be usable by other ports
without too much hacking, assuming doubles and u_int64_ts are passed and
returned the same way, and FP formats are IEEEish.
