            Bug ID: 66389
           Summary: sh2eb-linux-* is not recognized by configure
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: bugdal at aerifal dot cx
  Target Milestone: ---

The processor type sh2eb is not recognized by configure, at least not for Linux
targets, and the only way I could find to get a working big endian sh2 compiler
was to use sheb-linux-*, yielding default code generation for sh1 rather than
sh2. Binutils is affected by the same issue.

Reportedly this is a regression since 4.2.1 and binutils 2.17.
