New Revision: 160380

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=160380
Log:
        * cgraph.c (cgraph_edge_cannot_lead_to_return): Also check
        if caller is noreturn.
        * ipa-reference.c (analyze_function): Use ipa_ref_cannot_lead_to_return
        * ipa-ref.h (ipa_ref_cannot_lead_to_return): New function.
        * ipa-ref.c (ipa_ref_cannot_lead_to_return): New function.
        * ipa-pure-const.c (check_decl): Add IPA parameter.
        (state_from_flags): New function.
        (better_state, worse_state): New functions.
        (check_call): When in IPA mode, do not care about callees.
        (check_load, check_store): Update.
        (check_ipa_load, check_ipa_store): New.
        (check_stmt): When in IPA mode, use IPA checkers.
        (analyze_function): Use state_from_flags.
        (propagate): Check indirect edges and references.

breaks the bootstrap on darwin in the libjava build. The failure appears as...

The following http://gcc.gnu.org/ml/gcc-patches/2010-06/msg00692.html
It definitly avoids the ICE, but it would be nice to know if libstdc++
testsuite passes.

It does fix the bootstrap failure. I am currently regtesting (at gfortran -m32)
and should have the results for libstdc++ in a couple of hours.

When applied to r160481, it solved the problems for cris-elf with no
regressions compared to r160368.

On x86_64-apple-darwin10.3.0 I have bootstrapped successfully revision 160431
with revision 160380 reverted and revision 160454 with revision 160380 and the
patch in http://gcc.gnu.org/ml/gcc-patches/2010-06/msg00692.html. For the later
the regtest failures are those reported in
http://gcc.gnu.org/ml/gcc-testresults/2010-06/msg00587.html .

Note that the 2*16 failures for libstdc++ are due to revision 159362 (see also
the regress logs for ppc).
Martin Jambor knows about them and I'll fill a PR for yesterday later tonight
or tomorrow (filling PR against darwin sucks!-).

Obviously (as a duplicate) the patch fixes also pr44453.
