Re: ppc64 __attribute__((visibility ("hidden"))) and multiple TOCs

the TOC with sectcion anchors?

I have access to programs that overflow the TOC even with section anchors (this is with a modified PPC64 linux ABI in that pointers are 32bits so it takes even more to overflow the TOC). I have noticed that the linker does not combine duplicated TOC entries across objects which makes it even easier to overflow the TOC.

Thanks,
