            Bug ID: 22738
           Summary: sparc64-linux has 32-bit address space
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas

          Reporter: hjl.tools at gmail dot com
  Target Milestone: ---
            Target: sparc64-linux

Binutils configured for sparc64-linux reports:

Key to Flags:
  W (write), A (alloc), X (execute), M (merge), S (strings), I (info),
  L (link order), O (extra OS processing required), G (group), T (TLS),
  C (compressed), x (unknown), o (OS specific), E (exclude),
  p (processor specific)
address@hidden gas]$ 

So .dc.a is 4 bytes since sparc64-linux assembler defaults to 32-bit processor:

(gdb) p *stdoutput->arch_info
$2 = {bits_per_word = 32, bits_per_address = 32, bits_per_byte = 8, 
  arch = bfd_arch_sparc, mach = 1, arch_name = 0x4c58d4 "sparc", 
  printable_name = 0x4c58d4 "sparc", section_align_power = 3, the_default = 1, 
  compatible = 0x433c50 <bfd_default_compatible>, 
  scan = 0x433c80 <bfd_default_scan>, fill = 0x4340b0 <bfd_arch_default_fill>, 
  next = 0x5197a0 <arch_info_struct>}
(gdb) 

There is a mismatch between ELF file class and target processor.
