# commit 5b118558f9fb0620508d51c34c2cb5ba4f1f01c2

# PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version number
#
# To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so,
# this patch bumps the soname to ld64.so.2.
#
# In theory (or for testing purposes) this will also allow co-installing
# ld.so versions for both ABIs on the same system. Note that the kernel
# will already be able to load executables of both ABIs. However, there
# is currently no plan to use that theoretical possibility in a any
# supported distribution environment ...
#
# Note that in order to check which ABI to use, we need to invoke the
# compiler to check the _CALL_ELF macro; this is done in a new configure
# check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac,
# replacing the hard-coded value of default-abi in the Makefile.
