From: Michael Veksler <veksler@il.ibm.com> To: gcc-gnats@gcc.gnu.org, gcc-prs@gcc.gnu.org, gcc-bugs@gcc.gnu.org, nobody@gcc.gnu.org, weber@informatik.uni-kl.de Cc: Subject: Re: optimization/7175: Calculation yields different results for version optimized with -O2 Date: Sat, 10 Aug 2002 06:29:05 +0300 http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7175 The moment you will add at the beginning of your main(): fpu_control_t fpu_bits; _FPU_GETCW(fpu_bits); fpu_bits &= ~_FPU_EXTENDED; fpu_bits |= _FPU_DOUBLE; _FPU_SETCW(fpu_bits); Assuming you init "res" to zeros, you are goint to get a consistent result. This probably means that this PR is basically the same as PR/6914.
