From 1b7a0148f070deb07455f06a15ff13834c92f17b Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Fri, 3 Jun 2011 10:36:21 -0700 Subject: [PATCH] gcc: * config/i386/crtfastmath.c [!__x86_64__ && __sun__ && __svr4__] (sigill_hdlr): Correct insn, insn size. (set_fast_math) [!__x86_64__ && __sun__ && __svr4__]: Use movaps. gcc/testsuite: * lib/target-supports.exp (check_sse_os_support_available): Use movaps. libgfortran. * config/fpu-387.h [__sun__ && __svr4__] (sigill_hdlr): Correct insn, insn size. (has_sse) [!__x86_64__ && __sun__ && __svr4__]: Use movaps.
