Successful bootstrap and test for GCC8.4.0 on Darwin platforms.
General notes:
* GCC on Darwin depends on the installed “binutils”, typically provided by a
version of “Xcode" or “Xcode command line tools”. Unless noted otherwise, the
bootstrap sequences here make use of the last available xcode command line
tools and SDK for the platform version.
* Two bootstrap and test sequences;
1) Using a version of GCC+Ada as the bootstrap compiler, allowing a build and
test for Ada.
2) Using the Apple GCC or clang that relates to the installed command line
tools.
* In some cases, particularly with the earlier versions, the installed ‘atos’
is not really compatible with the versions of libsanitizer that are built with
GCC8. In that case, it’s usually better to install a version of
llvm-symbolizer and set the ASAN_SYMBOLIZER_PATH=/path/to/llvm-symbolizer.
* I don’t have enough physical hardware to cover all of the versions directly,
so some are (macOS hosted) VMs using VirtualBox. In these cases, timeouts are
not necessarily significant (noted in the relevant results).

Darwin9 (powerpc64)
powercp64-darwin9 will not bootstrap with the system ld64 (the binary size now
exceeds the [buggy] branch island limit in that tool). It is possible to make
the bootstrap with an updated ld64 with that limit fixed, and using -Os for the
stage1 compiler options. There are several public branches with fixed ld64
versions available - I used a version of https://github.com/iains/darwin-xtools

Darwin8 cannot be built with the last release of XCode for the system (2.5)
At least ld64-85.2.1 is needed.
the results here were obtained with the cctools/ld64 sources from the xcode
3.1.4 source release.

Re: Spam, bounces and gcc list removal
Hi, since the change to the new list management, there has been an uptick of spam getting through. Spam is bounced by my ISP, and this just resulted in a warning that there were too many bounces and that I would get removed from the list unless I confirmed it (which I then did). This has now happened a second time, and this question So, a request: Could the overseers either install more effective spam protection for the list as a whole (preferred) or relax the limit on bounces? is still valid. Some kind of reaction would be appreciated. Regards Thomas

Spam filtering was and is distinct from mailing list processing, and as you know it's a constant arms race. We're working hard to make the new installation of spamassassin as discriminating as possible. We're also working on the workflow to clean the web archives of spam that got through. > > or relax the limit on bounces? OK, there are a couple of settings over at: https://gcc.gnu.org/mailman/admin/gcc/bounce that law and we can think about, but I'd like to see the messages in question to figure out what happened. - FChE

Spam bouncing is evil and often hits an innocent person whose address has been faked by the sender of spam, making the source of bounces not better than the originator. I have been hit myself like that in the past when someone chose to use my address; fortunately I only received a mere 1000 of bounces or so. If caught and chosen not to be quarantined or stored in a spambox, spam is best silently dropped on the floor aka /dev/null. I would certainly recommend anyone making use of services provided by an ISP who bounces spam to contact their e-mail system administrator and enquire as to why they chose to do so. At worst I would change the ISP for their bad practices, and I think the decision to unsubscribe people whose ISP chose to bounce spam received through the mailing list is a reasonable one. Maciej

Just patch < mbox or git-am mbox > for example. Well, not everyone obviously as I don't, so please be careful speaking quantifiers. I apply inline patches with `git am -' by piping messages or attachments to the command directly from my e-mail client (with its `Pipe' command), so I don't care how any message or attachment has been encoded for transport as long as the patch hasn't come out damaged once decoded. I'd expect any sane e-mail client to support a similar command if it were to be used for software development the way we do it, though I realise that regrettably some may not be as capable. Maciej
