From e44a6d438db4848c2a555be773568a3cf7994206 Mon Sep 17 00:00:00 2001 From: Alexandru-Cezar Sardan Date: Mon, 26 May 2014 12:11:13 +0300 Subject: [PATCH] Fix E500 with SPE errors with the _Decimal64 type [gcc] 2014-04-21 Michael Meissner PR target/60735 * config/rs6000/rs6000.md (mov_softfloat32, FMOVE64 case): If mode is DDmode and TARGET_E500_DOUBLE allow move. * config/rs6000/rs6000.c (rs6000_debug_reg_global): Print some more debug information for E500 if -mdebug=reg. [gcc/testsuite] 2014-04-21 Michael Meissner PR target/60735 * gcc.target/powerpc/pr60735.c: New test. Insure _Decimal64 does not cause errors if -mspe. Upstream status: Accepted This solves upstream bug 60735 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60735).
