2016-07-21[ARM] Fix PR target/59833Aurelien Jarno2-3/+12
For Aurelien Jarno <aurelien@aurel32.net> On ARM soft-float, the float to double conversion doesn't convert a sNaN to qNaN as the IEEE Std 754 standard mandates: "Under default exception handling, any operation signaling an invalid operation exception and for which a floating-point result is to be delivered shall deliver a quiet NaN." Given the soft float ARM code ignores exceptions and always provides a result, a float to double conversion of a signaling NaN should return a quiet NaN. Fix this in extendsfdf2. gcc/ChangeLog: PR target/59833 * config/arm/ieee754-df.S (extendsfdf2): Convert sNaN to qNaN. gcc/testsuite/ChangeLog: * gcc.dg/pr59833.c: New testcase. From-SVN: r238584
