libgcc: check for fenv.h in dfp configure check

[gcc.git] / libgcc / ChangeLog

2013-11-08  Bernhard Reutner-Fischer  <aldot@gcc.gnu.org>

        * configure.ac (libgcc_cv_dfp): Extend check to probe fenv.h
        availability.
        * configure: Regenerate

2013-11-07  Uros Bizjak  <ubizjak@gmail.com>

        * config/i386/sfp-exceptions.c (__sfp_handle_exceptions): Handle
        FP_EX_DENORM.  Store result to volatile location after SSE division
        to close interrupt window.  Remove unneeded fwait after x87
        division since interrupt window will be closed by emitted fstp.
        Rewrite FP_EX_INEXACT handling.
