I would like to get started with how to improve code generation for a

For this example consider this C function for a reference counted type:

There was an array of structs roughly like so:

What about instead of our current odd way of identifying LTO objects
simply add a special ELF note telling the linker the plugin to use?
.note._linker_plugin '/./libltoplugin.so'
that way the linker should try 1) loading that plugin, 2) register the
specific object with that plugin.

Caused by http://gcc.gnu.org/ml/gcc-patches/2012-12/msg01229.html, reason is
that stack layout shouldn't change during and after reload.
I have a patch fixing it under testing.

The standard also specifies the behaviour of ~unique_ptrT,D in terms of
comparing the stored pointer with nullptr.

You are right, of course. Not a bug, but it's disappointing that it isn't. If
that comparison were against a value initialized unique_ptrT, D::pointer,
instead of

You mean combining -frtti and -fno-rtti compiles? Yes, that's fine,
though you need to prefer the -frtti version in case code from that
translation

vec_safe_is_empty is still more correct here.
The rest of the patch is OK.

The below patch fixes the build for AVR and SPU targets, which got broken
when the signature of build_function_call_vec changed. The patch passes
vNULL for the extra parameter added (arg_loc), which I hope is ok for
builtins?
If ok, could someone commit please? I don't have commit access.

We already pass --32 to assembler on x86. It should be OK to do it
in configure. OK
