Dear Martin,
Thanks for taking a look. I am sorry to have taken so long to get back to you
but I have had a myriad of other things to do.
Do you by any chance know, which variable is causing the trouble? I am afraid
that *.LCO doesn't help me very much. This is wading around in a part of gcc
that I know essentially nothing about.
If it is lto___mod_a_MOD___vtab_mod_a_T_a, then is the multiplicity of sections
that is preventing the resolution of the offset?
Thanks in advance
Paul

This patch enabled merge of x86 *vec_extract<PEXTR_MODE12:mode>_zext patterns

I suspect 4.9 has no support for 10.10.5, try 5.x instead.
