Bug ID: 63773
Summary: [meta-bug] Restoring darwin bootstrap for gcc 5.0
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: howarth at bromo dot med.uc.edu
Bootstrapping gcc trunk at r217227 requires the following patches on
x86_64-apple-darwin14...
https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00662.html
https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00661.html
to avoid GCC poisoning ctype macros through safe-ctype.h by moving the <string>
header include forward.
https://gcc.gnu.org/bugzilla/attachment.cgi?id=33843 from
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63622#c3
to prevent alias creation on targets that don't support aliasing
https://gcc.gnu.org/bugzilla/attachment.cgi?id=33915 from
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63534#c55
for disabling nonlocal goto receiver and fixing setjmp receiver
The previous patch from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63580#c4
is no longer required after the commit of r217222.
The accumulated fixes for test suite regressions include
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63534#c50
to eliminate breakage of the asan tests at -m32

--- Comment #3 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I'd like to help, but it's such a mess. There is not one PR per distinct issue,
but various things reported in long threads.
Regarding the first two patches (libcc1 and ipa-chkp.c), they are
straightforward and should be approved fast. Don't hesitate to ping them every
few days.
The "nonlocal goto and setjmp" patch has been committed.
But… the remaining patch (https://gcc.gnu.org/bugzilla/attachment.cgi?id=33843)
does not appear enough to restore bootstrap. I still get:
ld: illegal text reloc in 'std::strstream::strstream()' to 'construction vtable
for std::basic_ostream<char, std::char_traits<char> >-in-std::strstream' for
architecture x86_64
is there another patch required?

Yes, I have it in my tree. Yet I still get the following error during stage 1

What OS X release and Xcode are you on? I am currently testing
x86_64-apple-darwin14 with Xcode 6.1 and have access to test on
x86_64-apple-darwin13 with Xcode 6.1 and x86_64-apple-darwin12 with Xcode
5.1.1.

Sorry, stupid typo on my part in the latest build. Indeed, with the three
patches mentioned, my build is proceeding fine.

Current status of trunk: we need one patch [1] to bootstrap, and one more [2]
to help with some failures. I have submitted a libtool patch [3], but it
doesn't to change things drastically. Latest test results are here:
https://gcc.gnu.org/ml/gcc-testresults/2014-11/msg01024.html
PS: we also have a breakage in libstdc++
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63811), but Jonathan said on IRC
he'll commit a fix asap.

Regarding that one, it should be fixed in the top-level Makefile. The targets
that configure and build libcc1 in this Makefile call $(HOST_EXPORTS), which
should do the trick. Instead, it should probably do like lto, and use
$(HOST_EXPORTS) and $(POSTSTAGE1_HOST_EXPORTS) together for stages > 1.
Looking at Makefile.def, the only difference I see is that libcc1 is not
bootstrapped, so maybe we could fix it this way?

ACK - I think that's completely the right approach to one part of the problem.
- what's happening is that the analysis for the _bootstrap_ compiler's support
of the -static-libstdc++ is being used for the _stage#3_ build of libcc1
for clang [bootstrap] -static-libstdc++ is not supported and thus libcc1 links
with /usr/lib/libstdc++.dylib (which is not really what was intended).
for gcc [bootstrap] the support is mentioned - and then the -static-libstdc++
flag is provided to the libcc1 link (which then fails with…).
… the second issue - which is that we need a -B…. option for each library path
that will be used for spec-substitution (.a for .dylib).

I don't think we want to bootstrap libcc1 (that was what the patch was
removing).
Probably the right example is gnattools - or something similar that only builds
@stage#3.

The necessary -B options are already in POSTSTAGE1_HOST_EXPORTS, through
POSTSTAGE1_CXX_EXPORT.

I cannot find anything in the top-level Makefile that builds at stage3 and uses
POSTSTAGE1_HOST_EXPORTS, i.e. properly builds with the final compiler. Even
gnarls uses HOST_EXPORTS, so it would probably have similar problems. (Doesn't
it? I don't know cause I never build ada.)

… this ^ i.e. choosing the right one to use depending on
cross/disable-bootstrap/stage#n …
.. gnattools adds the -B options specifically in its Makefile.
interesting - so that also implies it will be affected by the bootstrap
compiler (although, of course, that pretty much has to be GCC for Ada). I must
confess I'd not looked beyond the handling of certain configure options.

I wonder if this needs to be done via HOST_LIBS like in the gcc directory. As
far as I can see, everything else linked against libstdc++.a is an executable
from the gcc directory. Adding the usage of HOST_LIBS to the libcc/Makefile.am
would seem to also require the libcc1/configure to also have...
# Libraries to use on the host. This will normally be set by the top
# level Makefile. Here we simply capture the value for our Makefile.
if test -z "${HOST_LIBS+set}"; then
HOST_LIBS=
fi
AC_SUBST(HOST_LIBS)
added as well and configure regenerated.
