[Qemu-devel] [PATCH 2/3] dyngen: fix some warnings about unused functions

[Mark McLoughlin <markmc@redhat.com>]

Warnings were:

  dyngen.c:292: error: ‘pstrcpy’ defined but not used

Only used with CONFIG_FORMAT_COFF

  dyngen.c:319: error: ‘swab32ss’ defined but not used

With ELF_USES_RELOCA, either swab32ss() or swab64ss() will
be used depending on ELF_CLASS. Easier to just mark them
both as unused.

  dyngen.c:334: error: ‘get16’ defined but not used
  dyngen.c:343: error: ‘get32’ defined but not used
  dyngen.c:352: error: ‘put16’ defined but not used
  dyngen.c:359: error: ‘put32’ defined but not used

Maybe be used for some host arches; easiest to mark them as
unused.

  dyngen.c:425: error: ‘elf_swap_phdr’ defined but not used

This one is completely unused; just delete.
