State-Changed-From-To: open->analyzed State-Changed-By: danglin State-Changed-When: Fri Nov 15 15:25:18 2002 State-Changed-Why: Problem confirmed. GCC currently uses __umoddi3 from libgcc2.c for the operation. We need to add pattern to allow use of $$rem2U when available. We don't currently have this routine in the millicode routines used with linux. I suspect there may be other 64-bit operations that are pessimized by using generic libgcc code. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7625
