Bootstrap is into stage2 now. Will take a couple of hours before it's done.
Thanks.

at least some of the regressions are wide-int related:

Patch for pdist regression
Here's a patch for the pdist regression. I'll need more info about
the gnat.dg/outer_agg_bitfield_constructor.adb problem.

In a build tree from 10 days ago, compiling
nested_agg_bitfield_constructor.adb took ca. 0:48 s. After the wide-int
merge, it's already running for several minutes.
All this doesn't guarantee that wide-int is the culprit, of course.
I'll check further, probably even running a bootstrap of the rev
immediately before the merge.

In fact, it was still running after two hours.

I did this now and indeed the tests pass in the last rev before the
wide-int merge.

Running the compilation with DTrace based profiled (instead of
rebuilding with profiling enabled) found the following top CPU
consumers:
__gnat_portable_no_block_spawn 994414500
system__os_lib__non_blocking_spawn 1002010800
make__compile_sources__compile.15427 1010527200
make__compile_sources__start_compile_if_possible.15545 1029687100
namet__name_chars__set_item 1248495500
snames__initialize 1710811700
namet__name_find 1750025500
So something strange seems to be happening in gcc/ada/named.adb
(Name_Find).

Thanks for the fix. The second part, fixing the pdist failures, is
still missing, though.
I haven't yet had an opportunity to look into the two gnat.dg testcases
that still time out.
Thanks.
