[Commits] r15844 - in /libdfp/trunk: ChangeLog README.user sysdeps/dpd/Versions sysdeps/soft-dfp/dpd/Versions

Author: ryanarn

New Revision: 15844

Log:
Libdfp soft-dfp had exported symbols for bfp<->dfp conversions, __dpd_extend*
and __dpd_trunc* since 1.0.0 exported but there were not implementations for
hard-dfp, so when an application is built and linked against the soft-df
libdfp and then run against the hard-dfp libdfp there are errors like the
following:

__dpd_extendsftd, version LIBDFP_1.0.0 not defined in file libdfp.so.1

This patch provides these symbol exports for hard-dfp as well so that the
implementations added for hard-dfp in an earlier checkin actually get built
for hard-dfp.

	* README.user: Updated with instructions for using #include <dfp/  >.
	* sysdeps/soft-dfp/dpd/Versions: Moved __dpd_extend* and __dpd_trunc*
	symbol definitions from here to...
	* sysdeps/dpd/Versions: here, since these are needed for all versions
	of libdfp, not just the soft-dfp version.
