             Bug #: 13278
           Summary: --plugin doesn't work on archive
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
        AssignedTo: address@hidden
        ReportedBy: address@hidden
    Classification: Unclassified


address@hidden slim-1]$ cat foo.c
int foo(void)
{
  return 0;
}
address@hidden slim-1]$ cat bar.c
int bar (void)
{
  return 0;
}
address@hidden slim-1]$ make NM=nm
/usr/gcc-4.7.0-x32/bin/gcc    -c -o bar.o bar.c
./ar --plugin
/usr/gcc-4.7.0-x32/libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/liblto_plugin.so
-rcsD lib.a bar.o
./ar --plugin
/usr/gcc-4.7.0-x32/libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/liblto_plugin.so
-rcsD lib.a foo.o
nm --plugin
/usr/gcc-4.7.0-x32/libexec/gcc/x86_64-unknown-linux-gnu/4.7.0/liblto_plugin.so
lib.a

bar.o:
0000000000000000 T bar

foo.o:
0000000000000001 C __gnu_lto_v1
0000000000000001 C __gnu_slim_lto
rm bar.o
address@hidden slim-1]$ 

The problem is we set the target type of archive to the target type of
the first member, which may not be a plugin object.
