[Bug tree-optimization/44736] Overeager -O1 optimization results in incorrect code generation
--- Comment #3 from rguenth at gcc dot gnu dot org 2010-07-01 08:20 --- (In reply to comment #2) Thanks for the lightening fast response. I wouldn't have known to look there, especially since older GCC versions did not have this problem. Is it because 4.5.0 has better optimizations such that the code surrounding this malloc is now optimized away in this situation? Finally, is this issue going to be resolved within GCC, or is the permanent fix going to be to ask developers to use -fno-builtin-malloc? We are going to ask developers to use -fno-builtin-malloc for now. I also think this is a glibc bug which should mark the hook variables volatile. So, can you file a bug in the glibc bugzilla as well? Thanks again. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44736

[Bug libstdc++/44480] [C++0x] Linear performance of begin() in unordered associative containers
--- Comment #5 from paolo dot carlini at oracle dot com 2010-07-01 10:46 --- I read your message and Howard' reply. I don't know what the others implementors did, but in the meanwhile I got feedback from Matt: essentially, he considers the issue in the very same ballpark of 579, having to do with a load factor low and which the user cannot control. At this point, I think that before doing anything I want to discuss the issue face to face in Rapperswil when 579 will be discussed. Missing special indications, we'll just implement a change very similar to Boost' solution, in time for 4.6.0. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44480

As I used cut paste for a few repeated stanzas, I just checked if
there was any more of the same.
Once you know what it is, it's easy to find in the patch:
[amyl...@laria ~]$ grep -A 5 -B 5 '^+[ ]*{' 44566-regclass-diff-3
static int
-ia64_register_move_cost (enum machine_mode mode, enum reg_class from,
-enum reg_class to)
+ia64_register_move_cost (enum machine_mode mode, enum reg_class from_i,
+enum reg_class to_i)
+{
+ enum reg_class from = (enum reg_class) from_i;
+ enum reg_class to = (enum reg_class) to_i;
{
/* ADDL_REGS is the same as GR_REGS for movement purposes. */
if (to == ADDL_REGS)
so this typo was specific to ia64.c

[Bug fortran/44742] ICE in gfc_conv_array_initializer
--- Comment #3 from burnus at gcc dot gnu dot org 2010-07-01 11:45 --- Regarding the version: Try gfortran -v -- that does not only show the version but also the data and (possibly) the SVN reversion. Regarding the test case: I think it would be helpful, if you could reduce it a bit. Usually, it works best by removing all unneeded lines of the failing file - at the same time eliminating the number of required modules. That can also be automatized using Delta, cf. http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction But the suggestion to try GCC 4.6 (or 4.4) is also helpful.

[Bug c++/44743] New: Parser does not recogize local variable in constant expression for member function pointers
The parser does not reject invalid code, but instead passes to the compiler.
The compiler fails with different internal compiler errors depending on the
optimization level. With levels -O2, -O3 and -Os, the compiler generates valid
object code without complaining anything.
How to reproduce?
# cat ice.cc
struct A {
inline void foo() {}
};
templatetypename T, void (T::*fnc)()
void call(){
T t;
(t.*fnc)();
}
templatetypename T
void deduce_type(void (T::*fnc)()){
callT,fnc();
}
int main() {
deduce_type(A::foo);
return 0;
}
# g++ ICE.cc -o ICE -Wall
ICE.cc: In function void call() [with T = A, void (T::* fnc)() = fnc]:
ICE.cc:8: internal compiler error: in expand_expr_real_1, at expr.c:7314

ICE.cc:6: internal compiler error: in make_decl_rtl, at varasm.c:1290
# g++ ICE.cc -o ICE -Wall -O2
If we use instead of a member function pointer a usual function pointer like in
the following code snippet
templatevoid (*f)()
void call(){
f();
}
templatetypename F
void deduce_type(void (*f)(), F){
callf();
}
# g++ -c ICE2.cc -o ICE2.o -Wall
ICE2.cc: In function void deduce_type(void (*)(), F):
ICE2.cc:24: error: f cannot appear in a constant-expression

[Bug fortran/44744] [4.6 Regression] Missed runtime error after revision 161550
--- Comment #1 from burnus at gcc dot gnu dot org 2010-07-01 14:53 --- I think it is not really a regression in terms of the code path. gfortran checks bounds of the form (tree dump) procedure(result,...) but not of the form procedure(tmp) result = tmp Thus, gfortran also misses (all versions): a(i:1) = f(b)*1.0 Thus, the RHS = LHS check is missing at some point (i.e. the call to gfc_trans_array_bound_check) - if there is an array temporary involved. Vaguely related: PR 32454. There is actually some bounds check for line 7. First, one for the LHS (is a(i:1) in the range?), which works just fine, and then for the RHS (simplified dump): D.1609 = size(b) D.1611 = D.1609 if (D.1611 0 D.1609 = 0) if (D.1611 0 D.1611 = 0) if (D.1611 0 D.1611 D.1609) atmp.14.data = __builtin_malloc (MAX_EXPR D.1611, 1); Thus - not surprisingly, the temporary is conforming with the the required size. Actually, I wonder why we generate checking code if it is known that the size fits, e.g. a(i:1) does not need a check as both in the declaration and in the usage, the bound is an integer constant; the optimizer should be able to fix this, but I think one can handle this already in the front end - at least for the lbound, one often knows the bounds. Something involving INTEGER_CST_P with TREE_INT_CST_HIGH and/or TREE_INT_CST_LOW should do ... Expected: If there is a temporary, one should not compare (uselessly) whether the temporary has the right size but whether the RHS matches the LHS. -- burnus at gcc dot gnu dot org changed: What|Removed |Added OtherBugsDependingO||27766 nThis|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44744

[Bug c++/44753] New: [4.5 Regression] class partial specialization error
The following code compiles on gcc-4.2/4.3/4.4 but doesn't on gcc-4.5, with
error: aggregate fooidentityint, 0 bar has incomplete type and cannot be
defined
template class T
struct identity
{
typedef T type;
};
template class T, typename T::type A
struct foo {};
template class T, T A
struct fooidentityT, A {};
int main()
{
fooidentityint,0 bar; // error here
}
g++ somehow is messed up because foo is defined, and it should pick the partial
specialization. If we comment the latter, it compiles, picking the main foo
definition.

[Bug tree-optimization/44736] Overeager -O1 optimization results in incorrect code generation
--- Comment #4 from opensource3141 at gmail dot com 2010-07-01 16:52 --- (In reply to comment #3) We are going to ask developers to use -fno-builtin-malloc for now. I also think this is a glibc bug which should mark the hook variables volatile. I tested using the volatile keyword inside the glibc header malloc.h, and that also serves as a workaround. However, I believe the meaning of volatile is something a bit different, and using the qualifier would prevent GCC from optimizing accesses to the hook variables independent of calls to malloc. The fundamental issue seems to be that there is a mismatch between how malloc behaves and how GCC thinks it behaves. It sounds like the best way to resolve that mismatch is to use -fno-builtin-malloc, the main drawback being that the developer has to be consciously aware of this when building the code. Otherwise, there will be a nasty surprise. So, can you file a bug in the glibc bugzilla as well? I have filed a bug there and referenced this one: http://sources.redhat.com/bugzilla/show_bug.cgi?id=11781 -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44736
