Date: Fri, 09 Nov 2012 01:44:00 -0000	[thread overview]
Message-ID: <bug-55246-4@http.gcc.gnu.org/bugzilla/> (raw)

             Bug #: 55246
           Summary: Define a macro for 16*1024*1024
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com
                CC: ubizjak@gmail.com


i386 backend has

i386.c:          || INTVAL (op1) >= 16*1024*1024
i386.c:          || INTVAL (op1) < -16*1024*1024)
i386.c:          if (INTVAL (op1) < -16*1024*1024
i386.c:              || INTVAL (op1) >= 16*1024*1024)
predicates.md:          && offset < 16*1024*1024
predicates.md:          && offset < 16*1024*1024

It is a magic number for 64-bit displacement.  We should define
a macro to make it consistent.
