From: hubicka@gcc.gnu.org To: gcc-bugs@gcc.gnu.org, gcc-prs@gcc.gnu.org, mhillary@btopenworld.com, nobody@gcc.gnu.org Subject: Re: optimization/7897: gcc3.2 fails building kdeaddons when using the -march=pentium4 flag Date: Wed, 09 Oct 2002 10:29:00 -0000 [thread overview] Message-ID: <20021009172918.14477.qmail@sources.redhat.com> (raw) Synopsis: gcc3.2 fails building kdeaddons when using the -march=pentium4 flag State-Changed-From-To: feedback->open State-Changed-By: hubicka State-Changed-When: Wed Oct 9 10:29:18 2002 State-Changed-Why: It is dealing with SSE registers. Looks like 7630 duplicate. We allow DImode in XMM and subreg DI->DF is actually the problem - we fail to reload DImode value to DFmode that is quite correct. Perhaps CLASS_CANNOT_CHANGE_MODE for FLOAT_REGS? I've raised the priority of the other bug, so I am keeping this medium http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7897
