            Bug ID: 20992
           Summary: sparcv9 should be equivalent to sparc64
           Product: binutils
           Version: 2.27
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org

proposed fix to gas/configure.tgt for sparcv9*

After configuring binutils --build=sparcv9-sun-solaris2.11, I expected that
gas(1) would not just be a 64-bit executable, but that it would generate 64-bit
objects by default, similar to GCC.  Instead, it generates 32-bit objects by
default.  
After some digging I found that gas/configure.tgt currently checks for a number
of variants of sparc, but eventually hits 'sparc*' and sets arch to
'sparclite'.  It seems like sparcv9 and sparc64 should be equivalent and set
arch=v9-64,
