             Bug #: 53568
           Summary: SH Target: Add support for bswap built-ins
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: olege...@gcc.gnu.org
        ReportedBy: olege...@gcc.gnu.org
            Target: sh*-*-*


Currently using built-in functions such as __builtin_bswap32 results in a
function call.  Instead of that SH's 'swap.b' and 'swap.w' combinations can be
used to implement the bswap patterns.
