             Bug #: 54496
           Summary: [M32C] - Improve address costs estimations
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: olegendo@gcc.gnu.org
            Target: m32c*-*-*


With rev. 190990 the target hook TARGET_ADDRESS_COST has been extended to
contain the mode of the addressed memory and the address space.

On M32C the costs estimations should be adjusted, since addresses in different
address spaces have different costs, at least when compiling with -Os.
