2015-09-28Update soft-fp from glibc.Joseph Myers82-136/+587
This patch updates the soft-fp code in libgcc from glibc. There are no changes here of significance to the use of soft-fp in GCC (and so no testsuite additions); it's simply an update to bring in the latest soft-fp version (which will also hopefully go into Linux 4.4 to replace the 15-year-old copy currently in Linux).
