[Bug target/37121] g++ create global symbol for inline function, which make link failed with multiple definitions
--- Comment #16 from ktietz at gcc dot gnu dot org 2009-04-21 08:27 --- (In reply to comment #15) (In reply to comment #14) or remove the ordinary C library function in lib64_libmingwex_a-wininterlocked.o and just keep the inline function ? That would be my first experiment. What depends on lib64_libmingwex_a-wininterlocked.o Danny we implemented int wininterlocked.c file the common interlocked symbols, because some of them should be inlined for performance reasons. To remove the inline version seems to be the best solution for me here. Because otherwise we would disallow a function pointer reference to it. Possibly we could make als define those symbols in wininterlocked.c as weak, does this help? Kai -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37121

--- Comment #40 from rob1weld at aol dot com 2009-04-21 12:30 --- (In reply to comment #0) I've found a major performance regression in gcc 4.0.0's optimization ... (In reply to comment #11) We need more analysis on these kinds of issues. So, we're doing a worse job on register allocation. Is that because the register allocator got worse, or because we're giving it a harder problem to solve? (In reply to comment #12) It is the latter and the pass which is responsible ... (In reply to comment #13) Tough, there is really not much that can be done about this ... Is this of any use ? Register Allocation by Puzzle Solving http://compilers.cs.ucla.edu/fernando/projects/puzzles/ This project consists in developing a new model for register allocation that has fast compilation time, produces code of good quality, is able to address the many irregularities found in common computer architectures and is intuitive enough to be easily understood. Our implementation produces Pentium code that is of similar quality to the code produced by the slower, state-of-the-art iterated register coalescing algorithm of George and Appel augmented with extensions by Smith, Ramsey, and Holloway.

[Bug rtl-optimization/39580] [4.5 regression] Revision 145204 caused libgomp.c++/collapse-2.C
--- Comment #4 from abel at gcc dot gnu dot org 2009-04-21 14:16 --- What happens in the test is that when pipelining, after several consecutive substitutions we end up with moving expressions r64=r16-r16 and r64=r16-r51 through r16=r51, after which both expressions become r64=r51-r51, as a result of substitution. When merging these expressions, we hit an assert in insert_in_history_vect. This assert tries to describe the situations when earlier different, and now same expressions would have similar entries in their history of changes vector, i.e. somewhere on their way up they were transformed on the same insn. The main thing in the assert is that both expressions are supposed to be equal before this transformation was recorded. Now we have a test case when this is not the case. I presume that we didn't hit this before because the situations like ' b = c; a = b - c; ' are quite rare. We have two choices: either to extend the assert to cover this case or to remove it completely. If we'd extend it, then the assert becomes not very useful, as it basically says that all variations in the above situation are possible. So I'm inclined just to remove it. This would not hurt correctness, only in extreme rare situations like this we'd not be able to find both expressions to move them up, but only the one, as history vector has a single entry per uid, and thus we'd be unable to perform unification. So I will bootstrap/regtest the below patch.

[Bug target/33036] LINUX_DYNAMIC_LINKER undefined in gcc-4.2.1/gcc/config/arm/linux-elf.h
--- Comment #1 from ramana at gcc dot gnu dot org 2009-04-21 14:28 --- LINUX_DYNAMIC_LINKER et al are defined in gcc/config/linux.h and the correct definition must reach this case. Looking at the config parameters for --host and --build , I can spot a typo of linuc-gnu instead of linux-gnu. That might be one reason why the build isn't working for you . arm-linux-gnueabi is a standard build and I bootstrap it regularly and many folks use crosstool to build such a cross configuration. You might consider using this for your purposes. Can you check with a 4.3 toolchain or a compiler of recent vintage with the correct parameters to --build , --host . Please also indicate the host platform on which you were trying this. -- ramana at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |WAITING http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33036

[Bug c++/39754] [4.5 Regression] ICE: tree check: accessed elt 2 of tree_vec with 1 elts in tsubst, at cp/pt.c:9248
--- Comment #6 from dodji at gcc dot gnu dot org 2009-04-21 14:40 --- In this test case (the last one), the short description of the problem is that we fail at getting canonical types of template arguments when said arguments have composed types. Let me give the longer description as well, so that I don't forget :) 1/ During the instantiation of Eint, we try to instantiate the default argument AT of the template B with T=int*. 2/ At that point, lookup_template_class selects the AX* specialization that was first seen in struct D. There, X was a typedef of W, W being a template parameter of struct D. 3/In the context of 1/, we try to tsubst AT with T=int* - actually we try to tsubst the AX* specialization of AT. In tsubst, we then try to reuse the typedef declaration of T, if T is a typedef. A problem arises in 3/ because T is seen as a typedef of W (remember 2/) but W doesn't have any meaning in the context of 1/, hence the crash. Normally, template arguments are converted to their canonical type variant before the stubst-ing process starts. The canonical type variant of a typedef type variant is basically its qualified main type variant. E.g. in typedef const int Foo, the canonical type variant of Foo is const int. The function doing that conversion is canonical_type_variant. The root cause of the problem is that canonical_type_variant doesn't give us canonical variants of composed types. E.g. in typedef int Foo; The canoniacl type variant of Foo* should be int*. The current implementation of canonical_type_variant returns Foo* instead of int* in that case. So I am testing some patches that change the implementation of canonical_type_variant atm. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39754
