The C++ option -fvisibility-inlines-hidden doesn't work on powerpc64-linux.
I don't understand the problem well enough to describe it well or to
provide a small test case that doesn't depend on using libstdc++. The
problem shows up with anything that uses <iostream>, and also with the
test g++.old-deja/g++.pt/ttp19.C which uses <vector>.
With current mainline and binutils 2.15, a program links successfully but
dies at runtime with an illegal instruction, apparently trying to execute
data. With binutils from CVS the link fails; for ttp19.C the message is
elm3b11% $INST/bin/g++ -m64 -fvisibility-inlines-hidden ttp19.C
.../bin/ld: /tmp/ccR7UhuH.o(.text+0x48): unresolvable R_PPC64_REL24 relocation
against symbol `std::allocator<char>::allocator()@@GLIBCXX_3.4'
.../bin/ld: /tmp/ccR7UhuH.o(.text+0x60): unresolvable R_PPC64_REL24 relocation
against symbol `std::allocator<char>::~allocator()@@GLIBCXX_3.4'
.../bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
This might well be a binutils problem rather than a GCC problem, although
a fix to binutils will also require updated GCC documentation about which
version of binutils is required for powerpc64-linux.
