To: libc-alpha
This patch, relative to a tree with
<https://sourceware.org/ml/libc-alpha/2014-09/msg00114.html> (pending
sparc testing),
<https://sourceware.org/ml/libc-alpha/2014-09/msg00129.html> and
<https://sourceware.org/ml/libc-alpha/2014-09/msg00151.html> (pending
powerpc64 testing) applied, removes the first column (patterns
matching configuration names) from shlib-versions, leaving
shlib-versions entry selection based purely on sysdeps directories.
An implication of this removal is that the default for any non-Linux
ports using NPTL will be the same SONAMEs for NPTL libraries as for
Linux (as those defaults, previously limited to .*-.*-linux.*, are
left in nptl/shlib-versions and nptl_db/shlib-versions).
Special host_os handling in configure.ac that was purely for
shlib-versions is removed. (The host_os setting is still used for
libc-abis - see
<https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding
that - but no entries there are affected by this change.)
Tested on x86_64 and x86 that the installed shared libraries are
unchanged by this patch.

I've forgotten about whatever change made this not break the multi-variant
(e.g. biarch) cases for generating gnu/lib-names.h. It appears that now
operates by assuming that most SONAMEs will be the same for all the ABI
variants, and requires that abi-variant-libfoo-soname variables be set in
sysdeps/.../Makefile for the ones that vary. I'm not particularly happy
with that. There should only be one flavor of file where SONAME strings
appear in the sources.
I think we need a more thoroughgoing overhaul of the shlib-versions
picture. I believe we already have consensus that all such things should
be organized purely via the sysdeps/ hierarchy rather than with any config
tuple matching. So this change could well be an appropriate incremental
step along the path to the clean overhaul. But I'd prefer to see a design
for that end state before we just whittle away with incremental changes
like this one. As is, it just feels to me like it's making something
baroque slightly differently baroque (and perhaps moreso), and not clearly
easier to grok than the status quo that (some) people already grok.
As to the tunnel-vision review of the patch per se, the only problem I see
is that the comments in shlib-versions still describe things in ways that
don't really make sense any more, e.g. "loose patterns at the end of the
list can give defaults."
Thanks,
Roland

Dealing with that is the next point on the list at
<https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>.

The only other things I know of are avoiding repeating the "Earliest
symbol set" information many times in some cases, and removing the
bitrotten --enable-oldest-abi support as previously discussed.

This patch version updates that comment (so instead it describes the
ordering of the various shlib-versions files, which is the key ordering
information given the files coming from sysdeps).
