IOW with:
% cat =ar
#!/bin/sh
cmd=$1
shift
/usr/bin/ar $cmd --plugin
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.0/liblto_plugin.so $*
I cannot reproduce the issue anymore.

That leaves us with the testcase that eventually is invalid. The testcase
is fixed when using -fno-fat-lto-objects and gcc-ar (which is not required,
or should not be required(?)

For me x64_64-linux version works if I use gcc-ar (both with and without

For non fat ("slim") LTO builds you need to use these tools yes. ar needs to
know the symbol table for its index and that needs LTO specific knowledge.
This follows other slim lto compi

So it seems that original testcase with fat files which used plain ar is indeed
correct and we have a real bug.

The C++ Standard says that "an inline function shall be defined in every

What you hit here is the V1 linker plugin API hack. We, for purpose, hide
COMDAT objects when we know we can hide them, because otherwise linker will
assign them PREVAILING and

Also note that binutils has default search path for plugin. If we installed our
linker plugin there, the ugly gcc-nm/gcc-ar wrappers would not be needed.
