I have been trying to use the BFD linker plugins support
that was added last year to binutils with the gcc plugin:
But as far as I can see it doesn't work.
I call it like this:
ar --plugin
/pkg/gcc-4.6/libexec/gcc/x86_64-unknown-linux-gnu/4.6.0/liblto_plugin.so.0.0.0 q
t.a ...
I verified the binutils objdir has plugins enabled.
But the resulting archive does not have the expected symbol table
from the LTO symbols. When I strace it the plugin is never
opened and when I set a break point the BFD plugin
code is not run:
(gdb) b plugin.c:191
Breakpoint 2 at 0x478f88: file ../../binutils/bfd/plugin.c, line 191.
(gdb) c
Continuing.
Program exited normally.
(gdb)
How is this supposed to work? It looks like the plugin BFD is not
tried by ar?
