Hello!

Attached patch implements TImode conversion for soft-fp. These files
are needed for X86_64 for floatint conversions between 128bit TImode
integers. Please note that the size of DImode integer is 64bits for
x86_64.

As TImode is not supported for all targets, it should be defined in
target header (sfp-machine.h), as shown in the patch, attached to
http://gcc.gnu.org/ml/gcc-patches/2007-04/msg00728.html.

The patch is diffed agains gcc config/soft-fp, but these files are
shared with glibc's soft-fp. This patch passes all gcc's floatint
tests for x86_64 target.

Additionally, a couple of oversights (i.e. DFtype should be used
instead of double) are fixed along the way.

As stated in http://gcc.gnu.org/ml/gcc-patches/2007-04/msg00729.html,
these files could be usefull for other targets, so I would like to ask
for an inclusion in libc's soft-fp library.
