--- Comment #5 from rob1weld at aol dot com 2010-05-04 06:52 --- Rainer: Fixed for 4.5.0. Thanks to our Solaris Expert for fixing that. It is (was) great fun to have to build (at least we used to, have to) gcc with both GNU's ld and Sun's to ensure there is (was) no breakage. Recently I was able to use only GNU's ld (except when trying to build _some_ of Sun's Source), which cut down on ifdef'ing (uglifying) patches.

--- Comment #6 from rob1weld at aol dot com 2010-05-04 07:00 --- Unless there are very important reasons (and I don't see any since the underlying libthread and libpthread implementation on Solaris 2 is identical, just the interfaces differ), please stick with the default, posix. _My_ reasons to test it for the gcc group was that --enable-threads=solaris _was_ a legal configuration option and so I tested it and made a BR. My reasons were set out in comments 2 and 4, I have nothing to add. This is now documented in install.texi to deter people who think they should use solaris on Solaris 2. Thanks for fixing the DOCs, can we pull the code too (or ifdef it out for OpenSolaris) to avoid having code in gcc that is no longer supported.

--- Comment #16 from siarhei dot siamashka at gmail dot com 2010-05-04 07:04 --- So basically what we have is that gcc miscompiles itself somewhere in the code where one of those ~7000 gcc_assert is used. The next step is to identify which one of them triggers this bad behaviour (bisecting not in the svn revisions, but in gcc source files by flipping the use of __builtin_unreachable-based vs. ordinary gcc_assert implementations) and extract a reduced testcase showing __builtin_unreachable failure. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42347

This is practically doubled if you have two different configurations to test, and I simply cannot afford that, given that this is a spare-time activity. That's why I'm even opposed to take patches, since than I'm forced to deal with issues as well. We hear you on that. This is an Enhancement (EG: I wish (someday in the future) that we had this feature) and I would have preferred it remain open until the need for the feature exceeded the lack of available time to implement it (as Eric pointed out we may cross that line shortly). I can settle for this being re-opening in the future and will accept WONTFIX for now, (since it would be a fair bit of work to get everything working correctly).

Yes, it's a subset of PR31588.

Thanks for your comments! FYI, my binutils are GNU ld (GNU Binutils) 2.20.1 20100303. I don't know when binutils was upgraded, but looking back, I see that at the end of april, results on alpha for this test were clean [1].

[Bug fortran/39427] F2003: Procedures with same name as types/type constructors
--- Comment #5 from damian at rouson dot net 2010-05-04 14:25 --- (In reply to comment #4) What a horrible rule... I'm not sure why you don't like it, but the reason for the rule is to have the ability to overload the intrinsic structure constructors. The intrinsic structure constructors are virtually useless for object-oriented programming (OOP) because they can't be used if the type has private data (required by the information-hiding philosophy of OOP) unless all components have default initializations (which only helps in trivial cases). It's standard in C++ (and I'd guess in most other OOP languages) for constructors to have the same name as the type. What could be more clear to the reader than type(vector) :: f f = vector(1.0,2.0) Once one adopts this approach, it touches every type you develop, so a compiler that doesn't support it becomes useless unless you're willing to change every constructor name to suit that particular compiler. It's already supported by IBM XL Fortran (my primary development platform), by Cray, by NAG (I think), and Intel has promised to support it in its next release. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39427
[Bug debug/43983] New: var-tracking needlessly throws away location info for SRAed vars
track_expr_p has:
4496 /* If this expression is really a debug alias of some other declaration,
we
4497 don't need to track this expression if the ultimate declaration is
4498 ignored. */
4499 realdecl = expr;
4500 if (DECL_DEBUG_EXPR_IS_FROM (realdecl) DECL_DEBUG_EXPR (realdecl))
4501{
4502 realdecl = DECL_DEBUG_EXPR (realdecl);
4503 /* ??? We don't yet know how to emit DW_OP_piece for variable
4504 that has been SRA'ed. */
4505 if (!DECL_P (realdecl))
4506return 0;
4507}
I'd say if the DECL_DEBUG_EXPR is a COMPONENT_REF, ARRAY_REF etc. from a
reasonably short type, the easiest thing would be just to let var-tracking
track the individual vars and let dwarf2out_var_location assemble them
together.

The reason why this doesn't hit us in libstdc++.a on x86-64 is that the STB_GNU_UNIQUE symbols locale-inst.o needs are in locale-inst.o rather than compatibility-ldbl.o. Looking into it.

[Bug c/43987] New: [4.5 regression] type-punning causes broken binaries unless -O0 is used
I noticed this when building busybox 1.16.1, but I also saw this in other code: When building with -O2 I get warnings like: 'warning: dereferencing type-punned pointer will break strict-aliasing rules' The produced binary is broken, in the case of busybox, the 'sed' applet segfaults. When adding -fno-strict-aliasing, the warnings disappear, but the resulting binary is still broken (with no warning or error indicating that something is broken). The same also happens with -O1 or -Os, only a -O0 binary will work. This used to work fine in gcc 4.4. I don't know how a test case would look like, as I don't know the code that breaks that closely. In my opinion, one of the following should happen: a) gcc 4.5 should produce code that works b) gcc 4.5 should throw a warning or error indicating that the code is incorrect -- Summary: [4.5 regression] type-punning causes broken binaries unless -O0 is used Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: thomas at archlinux dot org GCC build triplet: x86_64-unknown-linux-gnu / i686-pc-linux-gnu GCC host triplet: x86_64-unknown-linux-gnu / i686-pc-linux-gnu GCC target triplet: x86_64-unknown-linux-gnu / i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43987
