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.
