See: > http://sourceware.org/ml/binutils/2012-10/msg00050.html Interesting, I missed this. Why nm/ar/ld can't just support multiple plugins and load all plugins from its default plugin directory (where all installed compilers will drop one) and choose the one claiming the file? I see it would need some work on linker side if one plugin claims one file and other plugin other file, but there don't seem to be anything in the plugin API making this impossible and we can just error out in this case until mixing LTO from different compilers become fashionable.
