# PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version number
|
|
|
00db10 |
#
|
|
|
00db10 |
# To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so,
|
|
|
00db10 |
# this patch bumps the soname to ld64.so.2.
|
|
|
00db10 |
#
|
|
|
00db10 |
# In theory (or for testing purposes) this will also allow co-installing
|
|
|
00db10 |
# ld.so versions for both ABIs on the same system. Note that the kernel
|
|
|
00db10 |
# will already be able to load executables of both ABIs. However, there
|
|
|
00db10 |
# is currently no plan to use that theoretical possibility in a any
|
|
|
00db10 |
# supported distribution environment ...
|
|
|
00db10 |
#
|
|
|
00db10 |
# Note that in order to check which ABI to use, we need to invoke the
|
|
|
00db10 |
# compiler to check the _CALL_ELF macro; this is done in a new configure
|
|
|
00db10 |
# check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac,
|
|
|
00db10 |
# replacing the hard-coded value of default-abi in the Makefile.
