I have some mixed results, unfortunately.
OK:
i686, powerpc-darwin9 (bootstrapped with gcc-5.3) all supported langs.
x86_64-darwin{10..21} (bootstrapped with gcc-7.5) all supported langs.
Where I have bootstrapped D, that was using 11.3 as the bootstrap GDC.
results from:
https://gcc.gnu.org/pipermail/gcc-testresults/2022-May/760678.html
to:
https://gcc.gnu.org/pipermail/gcc-testresults/2022-May/760692.html
All of these show new fails (presumably because checking is off):
XPASS: c-c++-common/goacc/kernels-decompose-pr100400-1-2.c -std=c++98
(internal compiler error)
FAIL: c-c++-common/goacc/kernels-decompose-pr100400-1-2.c -std=c++98 (test for
excess errors)
XPASS: c-c++-common/goacc/kernels-decompose-pr100400-1-2.c -std=c++14
(internal compiler error)
FAIL: c-c++-common/goacc/kernels-decompose-pr100400-1-2.c -std=c++14 (test for

earlier x86 darwin is particularly noisy test-wise because there seem to be a
lot of newer AVX512 tests
that do not check for support from the assembler etc.
====
We do not expect darwin9-11 to bootstrap with host tools, they do not have
sufficient C++11 support.
However from Darwin12+ (macOS 10.8) we expect to be able to bootstrap with the
host clang, but:
Not OK:
x86_64-darwin{12..15} FAIL to bootstrap with host clang, this is a regression.
the reason is that "gcc/analyzer/region-model.cc” uses initializer_lists, and
it seems that <initializer_list>
is not transitively included by any used headers for _LIBCPP_VERSION < 4000. I
fixed that locally by
adding initializer_list into system.h (and adding INCLUDE_INITIALIZER_LIST to
the top of
gcc/analyzer/region-model.cc)
- with that change those versions do bootstrap and test OK***
OK:
x86_64-darwin{16..21} bootstrap OK with the host clang, and the test results
show no surprises c.f. the
results with gcc-7.5 as the bootstrap.
If there’s an rc2 (or it seems reasonable anyway) it would be nice to fix the
bootstrap with host tools.
thanks
Iain
*** I’ll do a patch for master/gcc-12 after the weekend (public holiday in the
UK tomorrow), if no-one beats me to it…
