[Bug c++/44808] [4.6 Regression] ICE: tree check: expected var_decl, have result_decl in gimplify_modify_expr
--- Comment #2 from jakub at gcc dot gnu dot org 2010-07-05 10:55 ---
I don't see anything odd on the value-expr (the variable res has been NRVed in
the FE to the RESULT_DECL) nor on the assignments from RESULT_DECL.
So, I think either we should guard this hunk in gimplify.c with TREE_CODE
(*from_p) == VAR_DECL instead of DECL_P (*from_p), or change the check in
tree.h in {,SET_}DECL_DEBUG_EXPR from VAR_DECL_CHECK to DECL_COMMON_CHECK.
There is nothing VAR_DECL specific on the lookups (all it needs is DECL_UID,
which RESULT_DECL and PARM_DECLs etc. have too). var-tracking will unlikely
use it though.

The NN=1 case is 9x slower than NN=8, which is again 3x faster than NN=7 and
NN=10, even though it is the same computation in all cases. Great news is, that
the figures themselves are much better than with gcc-4.4, but the variance
bothers me a bit.

[Bug c++/44822] Recusive functions optimize in unpredictable ways
--- Comment #2 from marco at technoboredom dot net 2010-07-05 14:46 --- (In reply to comment #1) recursive inlining is limited to a depth of 8. While the testcase may be interesting, does it have any practical relevance? Probably. The test case shows that the compiler fails to recognize that f() can be optimzed a *magnitude* better, unless we explicitly expand the call graph (NN1). The stock version (NN==1) of f() is the slowest. Certainly nobody looked to optimize for these funny callgraphs. It's still the call graph of f() only that f changes it's name in each call -- F0,3::f calls F1,3::f calls F2,3::f calls F0,3::f etc. -- marco at technoboredom dot net changed: What|Removed |Added Component|tree-optimization |c++ http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44822

--- Comment #3 from rguenth at gcc dot gnu dot org 2010-07-05 14:54 --- It's quite different as tail-recursion optimization doesn't apply if the functions are named differently. And the callgraph has an exponential number of edges which we usually do not flatten down to the point where tail-recursion will apply. What is indeed odd is that we optimize better with an expanded callgraph which we shouldn't. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44822

It turns out that the problem is that when build_function_type_skip_args
creates
the new type, TYPE_POINTER_TO for the new type is still pointing to the old
type.
When gimple_call_set_fndecl is used to change the fndecl to one with less
arguments, an ADDR_EXPR is built. The type of the ADDR_EXPR is obtained from
the
TYPE_POINTER_TO field of the new type, and thus has type pointer-to-old-type
rather than pointer-to-new-type. I'm testing the following patch. The idea
here is that calling copy_node has no advantage. In spite of the comment,
build_distinct_type_copy preserves attributes etc too, so it might as well
be used always. [I think the comment refers to some earlier logic, since
the change introducing build_distinct_type_copy post-dates it].

[Bug fortran/44742] ICE in gfc_conv_array_initializer

[Bug tree-optimization/41355] Type of ADDR_EXPR in CALL_EXPR not rebuilt when function is cloned
--- Comment #2 from hubicka at ucw dot cz 2010-07-05 19:02 --- Subject: Re: Type of ADDR_EXPR in CALL_EXPR not rebuilt when function is cloned It turns out that the problem is that when build_function_type_skip_args creates the new type, TYPE_POINTER_TO for the new type is still pointing to the old type. When gimple_call_set_fndecl is used to change the fndecl to one with less arguments, an ADDR_EXPR is built. The type of the ADDR_EXPR is obtained from the TYPE_POINTER_TO field of the new type, and thus has type pointer-to-old-type rather than pointer-to-new-type. I'm testing the following patch. The idea here is that calling copy_node has no advantage. In spite of the comment, The conditional you removed is about case where METHOD_TYPE is passed and this pointer is not removed. In this case we still want to produce METHOD_TYPE just with args adjusted. I think this functionality should be preserved. Are attributes attached to decl (not type) also copied?

[Bug c/44831] New: internal compiler error: verify_stmts failed when compiling wine
Howdy, This is a regression in gcc, but I haven't yet bisected it. Hopefully there is enough information to fix it without bisecting. gcc version used: aus...@midna:~/wine-git/dlls/netapi32$ gcc -v Using built-in specs.

[Bug bootstrap/44832] New: --enable-build-with-cxx Bootstrap comparison failure
r161856, bootstrapped with --enable-build-with-cxx, fails the bootstrap comparison on i386.o. By doing a binary search applying the first patch for PR44512 http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01765.html to older revisions, I found that the onset of these comparison failures is between revision 161800 and 161802. As 161801 was a fortran-only patch, 161802 seems the likely culprit. -- Summary: --enable-build-with-cxx Bootstrap comparison failure Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: bootstrap AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amylaar at gcc dot gnu dot org GCC host triplet: i686-pc-linux-gnu OtherBugsDependingO 44433 nThis: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44832

[Bug c/44715] Break in increment expression of for statement inconsistent with g++
--- Comment #4 from ecyrbe at gmail dot com 2010-07-06 05:28 --- (In reply to comment #3) Subject: Re: Break in increment expression of for statement inconsistent with g++ On Tue, 29 Jun 2010, pinskia at gmail dot com wrote: What does a break with a statement expression do for each frontend? Is it even valid to have a break there(without a statement expression)? The relevant contexts have expressions, so without statement expressions it's not possible to have break there. The C standard (I haven't checked C++) requires break (and continue, which probably has much the same issue) to be in a loop or switch body - but being elsewhere in the loop than its body isn't possible in standard C anyway. When I was fixing statement expression issues with jumps, and defining exactly what was permitted (bug 772), I didn't think of this particular issue. As i said in the clang bug tracker who triggered this issue initially : Here is what the c++ standard says : The break statement shall occur only in an iteration-statement or a switch statement and causes termination of the smallest enclosing iteration-statement or switch statement; control passes to the statement following the terminated statement, if any. So the break (if the expression statement extension is activated) is considered in the inner loop with this extension. And now here is what the c99 standard says : A break statement shall appear only in or as a switch body or loop body But in C, the loop body does not contain the expression statement. So the break applie only to the outer loop in C. The result is that gcc is correct in this behavior. C++ and C should differ in this matter. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44715
[Bug fortran/44742] ICE in gfc_conv_array_initializer
--- Comment #10 from burnus at gcc dot gnu dot org 2010-07-06 05:33 --- (In reply to comment #9) Even shorter: integer, parameter :: N = 256 Note: N=256 is the smallest number for which it fails. Workaround: Use a sufficiently large -fmax-array-constructor=n, e.g. -fmax-array-constructor=65536 (65536 = 256**2; default is 65535) Side remark: It is not particularly efficient to use a huge static variable. If you use PARAMETER (as in your example), that leads to huge .mod files and on assignment to large code. If you use a normal variable (with [implied] SAVE), a non-zero initializer will be written as is into the assembler file, which makes the binary unnecessarily large. For variables, using initialization at run time is the better choice for large arrays. The best solution for PARAMETER depends on the purpose. -- burnus at gcc dot gnu dot org changed: What|Removed |Added Keywords||ice-on-valid-code http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44742
