I'd like to point to this part of configure.ac:
AC_MSG_CHECKING(for architecture-specific fixed-point math routines)
AC_ARG_ENABLE(fpm, AC_HELP_STRING([--enable-fpm=ARCH],
[use ARCH-specific fixed-point math routines
(one of: intel, arm, mips, sparc, ppc, 64bit, default)]),
[
case "$enableval" in
yes) ;;
no|default|approx) FPM="DEFAULT" ;;
intel|i?86) FPM="INTEL" ;;
arm) FPM="ARM" ;;
mips) FPM="MIPS" ;;
sparc) FPM="SPARC" ;;
ppc|powerpc) FPM="PPC" ;;
64bit) FPM="64BIT" ;;
float) FPM="FLOAT" ;;
*)
AC_MSG_RESULT(failed)
AC_MSG_ERROR([bad --enable-fpm option])
;;
esac
])
if test -z "$FPM" && test "$GCC" = yes
then
case "$host" in
i?86-*) FPM="INTEL" ;;
x86_64*) FPM="64BIT" ;;
arm*-*) FPM="ARM" ;;
mips*-*) FPM="MIPS" ;;
sparc*-*) FPM="SPARC" ;;
powerpc*-*) FPM="PPC" ;;
# FIXME: need to test for 64-bit long long...
esac
fi
AC_MSG_RESULT(${FPM=DEFAULT})
if test "$FPM" = "DEFAULT"
then
AC_MSG_WARN([default fixed-point math will yield limited accuracy])
fi
You should probably set it to 64BIT, which is what I did for amd64.
The others are assembler implementations.
