             Bug #: 54563
           Summary: [4.7][C++11] MacOS 10.8, ICE in redirect_eh_edge_1, at
                    tree-eh.c:2215
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: driver
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: david.abdurachmanov@gmail.com


Created attachment 28184
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28184
Pre-processed testcase

Tested with 190338 (pre-4.7.2) and 188597 (4.7.1). It only happens with double
and float. If you switch to int and pow function instead of powf it works fine.
It crashes only on C++11. Compiled files with -ansi (no C++11), exit code 0.

Current workaround/fix is to use std::pow() in the code.

GCC compiled with LLVM/clang on Mac OS X 10.8, Xcode 4.4 (build: 4F250)

Apple headers are broken then, powf isn't marked throw ().  Of course, we
shouldn't ICE on it though.

--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-09-14 16:17:38 UTC ---
I'd say the bug is somewhere on the C++ FE side, this is a
DEF_C99_C90_RES_BUILTIN, in -std=c++03 -O2 we don't ICE on it, but with -O2
(-std=gnu++03 or -std=c++11 or -std=gnu++11) somehow it is marked as builtin,
but doesn't inherit throw () from the builtin.
IMHO that doesn't make sense.  Either it is not builtin and we therefore
shouldn't treat it as such, or it is builtin and then we should know that it
never throws.
Sure, tree-ssa-math-opts.c could have added lots of
maybe_clean_or_replace_eh_stmt and gimple_purge_all_dead_eh_edges calls just in
case or give up optimizing if the calls can throw, but none of those builtins
really ever throw, so my preference would be to fix this there.  Jason?

I tend to agree; this isn't the only place in the middle-end this could cause
trouble.  The handling of pow/powf in reassociation comes to mind as another
place where this could cause trouble.

Seems the C++ FE ignores the nothrow attribute from builtins and instead just
uses its own cfns.gperf.  pow is in there, but powf/powl is not (as C++03 is
based in C90).  Even in C++11 powf/powl isn't considered throw().

gcc48-pr54563.patch

Actually it doesn't seem to be too hard to handle it in execute_cse_sincos, the
gsi_replace calls already pass true as last argument, so no need to call
maybe_cleanup_eh_stmt, just gimple_purge_dead_eh_edges needs to be called if
we've changed the last stmt in a bb.  Untested yet.
