[Bug tree-optimization/21732] New: -ftree-dump-all-details hangs during *.c.t24.copyprop or *.c.t38.copyprop2
When dumping the trees during compilation GCC-4.1-2005010[1,8] went into an endless loop during the *.c.t22.copyprop or the *.c.t37.copyprop2 dump, thus generating larger and larger files. After the file reaches 2GB in size gcc stops. The same happens with gcc-4.1-20050515 in the steps *.c.t24.copyprop or *.c.t38.copyprop2. The dumper seems to follow and print a copy propagation chain like this in all the cases: A->B->A->B->A->B->... I've observed this behaviour with many source files. -- Summary: -ftree-dump-all-details hangs during *.c.t24.copyprop or *.c.t38.copyprop2 Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: minor Priority: P2 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: Ralf_Recker at gmx dot de CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21732

[Bug tree-optimization/21639] poisoned ggc memory used for -ftree-vectorize
--- Additional Comments From dorit at il dot ibm dot com 2005-05-24 11:53
---
I can reproduce this problem on powerpc-apple-darwin, even without the
options "-maltivec -mabi-altivec" (which means that no simd vectorization takes
place). What happens is that the scalar_evolution_info hash table is corrupted
between vectorization pass and tree_unroll_loops_completely pass. It looks like
this corruption takes place during pass_lower_vector_ssa (which is enabled by -
ftree-vectorize), when executing the todo_flags_finish for this pass.
The scalar_evolution_info htab before pass_lower_vector_ssa looks like this:
==
after execute pass:
(classify_chrec {0, +, 1}_1
affine_univariate
)
(classify_chrec
(classify_chrec {1, +, 1}_2
affine_univariate
)
(classify_chrec {0, +, 1}_2
affine_univariate
)
(
-
3 affine univariate chrecs
0 affine multivariate chrecs
0 degree greater than 2 polynomials
0 chrec_dont_know chrecs
-
4 total chrecs
1 with undetermined coefficients
-
21 chrecs in the scev database
55 sets in the scev database
73 gets in the scev database
-
)
==
After pass_lower_vector_ssa the scalar_evolution_info htab looks like this:
==
(classify_chrec <<< Unknown tree: >>>
)
(classify_chrec
(classify_chrec <<< Unknown tree: >>>
)
(classify_chrec <<< Unknown tree: >>>
)
(
-
0 affine univariate chrecs
0 affine multivariate chrecs
0 degree greater than 2 polynomials
0 chrec_dont_know chrecs
-
4 total chrecs
1 with undetermined coefficients
-
21 chrecs in the scev database
55 sets in the scev database
73 gets in the scev database
-
)
==
Removing the "TODO_ggc_collect" from the todo_flags_finish of
pass_lower_vector_ssa solves the problem (in tree-complex.c):
==
struct tree_opt_pass pass_lower_vector_ssa =
{
"veclower", /* name */
gate_expand_vector_operations, /* gate */
expand_vector_operations,/* execute */
NULL,/* sub */
NULL,/* next */
0, /* static_pass_number */
0, /* tv_id */
PROP_cfg,/* properties_required */
0, /* properties_provided */
0, /* properties_destroyed */
0, /* todo_flags_start */
TODO_dump_func | TODO_update_ssa /* todo_flags_finish */
-| TODO_ggc_collect | TODO_verify_ssa
+| TODO_verify_ssa
| TODO_verify_stmts | TODO_verify_flow,
0/* letter */
};
==
Paolo, is the above solution ok with you? If so, I'll go ahead and prepare a
patch. Alternatively, if ggc_collect is really required here, then adding a
call to scev_reset() would also solve the problem (again, in tree-complex.c):
==
expand_vector_operations (void)
{
block_stmt_iterator bsi;
basic_block bb;
FOR_EACH_BB (bb)
{
for (bsi = bsi_start (bb); !bsi_end_p (bsi); bsi_next (&bsi))
{
expand_vector_operations_1 (&bsi);
update_stmt_if_modified (bsi_stmt (bsi));
}
}
+
+ scev_reset ();
+
}

If not, you should not have to modify my pass since it is only showing the problem by doing TODO_ggc_collect. You have to make sure that scev_reset is called at the appropriate time, or that the contents of the scalar evolution hash table are reached during garbage collection. In other words, Janis is correct saying that this is a latent bug. Doing a TODO_ggc_collect after lower_vector_ssa may be overkill, and I'm ok with removing it, but then you are only papering over the real problem. If you have some time to spare, use a --enable-checking=gcac compiler, and the failure will likely happen much earlier. Paolo -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21639

I think passes within the loop optimizer can assume that the scev information cached in the scev htab can be safely used. During vectorization analysis some new entries in the scev htab are initialized, and these are valid to be used by subsequent passes. If no transformation takes place during vectorization then there's no need to invalidate this information. So I don't think we're missing a call to scev_reset in the vectorizer. The problem is more likely around the fact that ggc_collect, for some reason seems to free up data that is still pointed to from scalar_evolution_info. > If you have some time to spare, use a --enable-checking=gcac compiler, and the failure will likely happen much earlier. thanks for the tip > You have to make sure that ... the contents of the scalar evolution hash table are reached during garbage collection. any (other) hints on how to do that?

[Bug target/21738] New: MIPS libsupc++ built with small data
MIPS does not yet have relaxation support in binutils. Instead, in line with MIPS's own compiler, there is support for small data/bss sections, with appropriate shorter relocations. What size of data goes in those sections is determined with the MIPS target specific command line option -G. However libstdc++ and libsupc++ are built with the default -G value of 8. This means that if a sufficiently large application is built which requires the user to use a smaller value of -G, they are stuck. When brought up on the gcc mailing list around 2005-04-18, three solutions were suggested: a) multilibbing with -G 0. However this adds to multilib hell, and doesn't allow users to have some sdata support with e.g. -G 4. b) providing a configure time option to set the default -G option. However the choice of whether that is needed or not is application specific, not compiler specific. Completely separate compiler builds should not be needed for different applications. c) A new -m option to allow the MIPS backend to generate relocations that assume data is not in the small data section, but still output data into the small data sections. Then libstdc++ / libsupc++ would be built with this new option. Some other ports have this option such as PowerPC where this is the default method of operation (-msdata-data). This would admittedly result in some relocations within the libraries being larger than necessary. However application references to the libraries would be unaffected. No conclusion was reached, but it seemed to me and Zack Weinberg that the latter seemed a reasonable compromise. The PowerPC precedent is compelling. However I have looked at the MIPS backend and it requires someone more familiar with this code than I am to implement this option. My thoughts now are that I believe the easiest approach is to introduce a new mips_section_reloc_threshold variable that would default to the same value as mips_section_threshold (the present -G value). On supplying the new -mno-sdata-relocs option, mips_section_reloc_threshold would be set to 0. Almost all existing uses of mips_section_threshold in mips.c would be renamed to mips_section_reloc_threshold. But the rest is a bit fuzzier to me: sdata appears easy to handle in mips_select_rtx_section(), but sbss would require a change to mips_in_small_data_p, which is also used for TARGET_IN_SMALL_DATA_P. I would appreciate someone helping fill in the last blank. -- Summary: MIPS libsupc++ built with small data Product: gcc Version: 3.4.4 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: jifl-bugzilla at jifvik dot org CC: gcc-bugs at gcc dot gnu dot org GCC target triplet: mipsisa32-elf http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21738

[Bug regression/21740] New: template mismatch in 3.4 and 4.1
hi, the following code compiled properly in 3.3.5:
#begin code
/* bind 2nd parameter in a 2 parameters metafunction */
template< template class MetaFunc, typename B>
struct bind_2 {
template
struct bound {
typedef typename MetaFunc::type type;
}; };
template
struct Fx{
/* refer int 2 steps to Fx */
typedef typename bind_2< Fx, int >::template bound::type type;
};
template
struct Fx{
typedef double type;
};
#end code
When compiling with gcc 3.4.3 or 4.1 (recent CVS) i get:
bug.cpp:16: error: type/value mismatch at argument 1 in template parameter list
for `template class MetaFunc, class B> struct bind_2'
bug.cpp:16: error: expected a class template, got `Fx'
bug.cpp:16: error: expected unqualified-id before "template"
The strange thing is that if Fx is defined bi-recursively (instead that
recursively) it compiles on 3.4 and 4.1 too:
This is the working workaround:
#begin code
template
struct Fx;
template
struct Fy;
template
struct Fx{
typedef typename bind_2< Fy, int >::template bound::type type;
};
template
struct Fx{
typedef double type;
};
template
struct Fy{

[17:37] < tromey> ok [17:37] < rth> we would have to create hidden aliases for all native methods, and Just Know to use that alias when building the class table. [17:38] < rth> so i guess it's not that tricky. just a bit o coordination between c++ and java front ends. [17:38] < tromey> oh, I see... modify g++ to also emit the hidden aliases [17:38] < rth> It does assume that cni methods are linked together with its java class. [17:38] < rth> yes. [17:39] < tromey> at the moment there is no other way to really use cni methods [17:39] < tromey> so that is fine, I think [17:40] < rth> i'll see what i can come up with. [17:40] < tromey> thank you And this is reason why it works just fine on ppc-darwin, because darwin always use the function address and not a stub/plt entry for the function pointers. -- What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed||1 Last reconfirmed|-00-00 00:00:00 |2005-05-24 18:15:46 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21692

In FC4 we use java-gcj-compat to create a libjawt.so symlink in
/usr/lib/jvm/jre/lib/i386 (via alternatives).Programs running
System.loadLibrary("jawt") should find this without users having to set
LD_LIBRARY_PATH or -Djava.library.path. One answer is to let packagers set the
default java.library.path at configure time.

[Bug libfortran/21621] Inconsistency with binary sequential output
--- Additional Comments From jblomqvi at cc dot hut dot fi 2005-05-24 20:02 --- Well no, the standard does not specify how unformatted sequential record markers are implemented. In short, gfortran uses markers of type off_t, which is 64 bits on operating systems with large file (LFS) support. Today, that is most OS:es in common use. g77 AFAIK uses markers of type long, that is 32-bits on most 32-bit platforms and 64 bits on 64-bit platforms. See also PR 19303. Also note that Bud Davis is apparently currently working on pluggable record markers, which should allow gfortran to add some kind of g77 compatibility flag. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21621

[Bug target/21742] New: unrecognized insn for struct-layout-1 tests with complex members
Generated tests t154 and t199 from gcc.dg/compat/struct-layout-1 fail with an ICE compiling c_compat_y_tst.o with -m64 on powerpc64-linux. The first started failing on 20050424, the second on 20050501, and both have failed regularly since then, but it seems to be a latent bug because results for regression hunts don't match up with those dates. I'll attach minimized test cases for both.

[Bug libfortran/21333] in_pack / in_unpack alignment issues
--- Additional Comments From tkoenig at gcc dot gnu dot org 2005-05-24
22:40 ---
For 4-byte complex, an option is to check the alignment at runtime.
If the complex is aligned on an 8-byte boundary, it should be
perfectly OK to call the 8-byte-integer routines.
The check could be done with a macro like this:
#define GFC_ALIGNMENT_I8(a) (((size_t) (a)) & 7 == 0)
#define GFC_ALIGNMENT_I4(a) (((size_t) (a)) & 3 == 0)
and the code look like
if (size == 8)
{
if (GFC_ALIGNMENT_I8(ptr))
return internal_pack_8(whatever)
else if (GFC_ALIGNMENT_I4(ptr))
return internal_pack_c4(whatever)
/* Fall through to generic routine */
}
OK in principle? Too horrible to contemplate?

For example, modify ciotst.f to: program ciotst call cio write(*,*) 'Hello world.' call cio end The g77 output is: foo bar baz Hello world. foo bar baz as you would expect, but the gfortran output is in the wrong order (as well as missing the final "baz" in my unpatched gfortran) because of missing flushes: foo bar Hello world. bazfoo bar (If you look in libf2c you'll see that it uses fflush in a number of places.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20179

[Bug libstdc++/20823] frv-unknown-elf doesn't build: GCC_NO_EXECUTABLES unexpanded
--- Additional Comments From kcook at gcc dot gnu dot org 2005-05-25 01:11 --- > /home/hp/cvs_areas/combined/combined/libstdc++-v3/configure: line 1545: GCC_NO_EXECUTABLES: command not found This was due to my changes. This error was simply due to a mismatch in aclocal versions back when I was nuking the acconfig.h. Specifically this checkin: http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/libstdc%2b%2b-v3/configure.diff?r1=1.429&r2=1.430&only_with_tag=MAIN&f=h Note the date corresponds perfectly with the error. It was corrected with the next checkin to configure the next day. Moreover, I updated the documentation to show the automake 1.9.3 requirement, as the GCC_NO_EXECUTABLES macro is using AC_DEFUN_ONCE which aclocal ignored until version 1.9.3. Marking bug as fixed. -- What|Removed |Added Status|ASSIGNED|RESOLVED Resolution||FIXED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20823

--- Additional Comments From fitzsim at redhat dot com 2005-05-25 02:01 --- Are you using focus-follows-mouse? If so, this is a known problem; a change in a window's active state causes an expose event on the entire window, which triggers a repaint. We need to find a way to prevent that expose event in the gtk peers. -- What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed||1 Last reconfirmed|-00-00 00:00:00 |2005-05-25 02:01:17 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21604

[Bug c++/21746] New: Compiler will not create references of abstract types
Consider the code:
class A {
public:
virtual void foo() = 0;
};
class B : public A {
public:
virtual void foo() {}
};
int main()
{
const A &a = B(); // <-- here
return 0;
}
in g++-4.0, as it comes pre-installed on Mac 10.4, I get the error:
$ g++ -c g++4-bug.cc
g++4-bug.cc: In function `int main()':
g++4-bug.cc:15: error: cannot allocate an object of abstract type 'A'
g++4-bug.cc:3: note: because the following virtual functions are pure within
'A':
g++4-bug.cc:5: note: virtual void A::foo()
However, this code compiles without complaint on the g++-3.4 that comes
preinstalled on this system. I don't know whether this has been fixed since
gcc-4.0, but it doesn't seem to me like there's any reason for gcc to reject
this code.
Thanks,
Michael
