[Bug c/12245] [4.2/4.3/4.4 regression] Uses lots of memory when compiling large initialized arrays
--- Comment #42 from hubicka at gcc dot gnu dot org 2009-02-22 11:21 --- Actual representation of constructor don't seem to be major problem here. We seem to build _a lot_ (117MB) of CONVERT exprs just to call fold on it and convert integer to proper type, so counting in INTEGER_CSTs should be just slightly less than half of memory needed. This seems quite silly. The patch to not use HOST_WIDE_INT or similar for counting should save another 70MB of garbage (and speed up compilation), so perhaps you could dig it out? :)) Following patch: Index: convert.c === --- convert.c (revision 144352) +++ convert.c (working copy) @@ -749,6 +749,11 @@ convert_to_integer (tree type, tree expr break; } + /* When parsing long initializers, we might end up with a lot of casts. + Shortcut this. */ + if (TREE_CODE (expr) == INTEGER_CST) + return fold_unary (CONVERT_EXPR, type, expr); + return build1 (CONVERT_EXPR, type, expr); case REAL_TYPE: Cuts gabrage production in half: c-typeck.c:6472 (output_init_element) 0: 0.0% 47910400:100.0% 45541112:23.7% 26342936:99.5% 19 ggc-common.c:187 (ggc_calloc) 67094608:46.1% 0: 0.0% 67162736:34.9% 1088: 0.0% 58 tree.c:1004 (build_int_cst_wide) 78264768:53.8% 0: 0.0% 78266496:40.7% 0: 0.0%3261068 Total 145570627 47910416 192171521 26481588 3275033 source location GarbageFreed Leak OverheadTimes I will give the patch testing, but I am not too hopeful it will just work. ;) Honza -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=12245

So, please stop wasting yours and others time and please post a precise bugreport that _explains_ what you think is going wrong. On one or max two screens of text, please. From the bug report guide, you will note following bullet: Bugs in releases or snapshots of GCC not issued by the GNU Project. Report them to whoever provided you with the release FYI, miro (or whatever) is not issued by the GNU project. http://gcc.gnu.org/wiki/MIRO svn co svn://gcc.gnu.org/svn/gcc/branches/miro miro Who issues it ? please post a precise bugreport that _explains_ what you think ...

Two ways to fix this, a simple exclusion or fix all the warnings. To be honest, I don't even know _what_ are you reporting ... This much we know.

--- Comment #5 from steven at gcc dot gnu dot org 2009-02-22 12:59 --- Indeed. But Rob, Pinski has a point: There really are better things to spend your time on than building development branches. Such branches are often highly experimental or very unstable, so bugs are not usually tracked in bugzilla but in the branch maintainer's head or email box. We only track bugs on branches for some of the higher-profile branches that are more-or-less stable and close to being merged (like the alias-improvements branch, or LTO). -- steven at gcc dot gnu dot org changed: What|Removed |Added Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Last reconfirmed|-00-00 00:00:00 |2009-02-22 12:59:32 date|| Summary|[miro] revision 144368 -|[miro] branch listed as |make -i check autogen |active development branch |fixinclude test FAILURES |appears to be dead http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39265
[Bug c++/22635] OVERLOAD should not be a linked list of trees
--- Comment #10 from steven at gcc dot gnu dot org 2009-02-22 14:01 ---
Trees were refactored, and we currently have:
struct tree_base
{
ENUM_BITFIELD(tree_code) code : 16;
/* 48 bits for various bitfield flags */
union tree_ann_d *ann;
} /* So on a 64-bit host this is 128bits = 16 bytes */
struct tree_common
{
struct tree_base; /* 16 bytes */
tree chain; /* 8 bytes */
tree type; /* 8 bytes */
} /* So on a 64-bit host, tree_common is 32 bytes */
struct tree_overload
{
struct tree_common; /* 32 bytes */
tree function; /* 8 bytes */
}
So in total 40 bytes per tree_overload. If a single linked list would really
be sufficient, then the ideal tree_overload would be 16 bytes (two pointers).
In reality, there are a few flags used on tree_overload, so two pointers is not
enough. Let's say we use 4 bytes for that. Then we have an overhead of
(40/(16+4))*100% = 100% overhead.
In any normal engineering project, 100% overhead would be reason for distress.
However, as long as the G++ front end are comfortable using trees instead of
front-end specific structures in the parser, we can't do any better at this
point. The overhead is much less than it was in the past. It was 3% before
the tree refactoring, so it will be much less now. And like Gaby already said:
If there are not so many of them (tree_overload objects) then it is not very
important (to squeeze out every last bit of overhead).
Therefore, closing as FIXED by Dan's refactoring.

This system has a 113-bit significand floating point type. The random number generator requires 12 integers to seed the 3 internal and independent KISS generators (each KISS requires 4 seeds). The first KISS generator produces the first 32-bits of the significand, the 2nd KISS prng gives the next set of 32 bits, and the last KISS prng provides the remaining bits. The only portable way to seed random_number is to do something like integer, allocatable :: seeds(:) call random_seed(size=i) allocate(seeds(i)) ! ! Set seeds(i) here ! seeds = (/ (j, j=1, i) /)! Obviously, there are better choices! call random_seed(put=seeds) deallocate(seeds) A few other points. gfortran will mix your seeds with some system entropy to try to limit/prevent a bad choice of seeds. Additionally, if you harvest a real(4), reseed the generator, and then harvest a real(8). The first 24 bits of the real(8) will match the 24 bits of the real(4). If you have other questions about random_seed or random_harvest, it may be best to ask on the fort...@gcc.gnu.org list. -- kargl at gcc dot gnu dot org changed: What|Removed |Added Status|WAITING |RESOLVED Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39266

How about this patch?
1. Only reduce DI mode when -Os
2. Ignore TYPE_USER_ALIGN, so that stack realign happens for case in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39137#c28, which IMHO is
acceptable.

[Bug c++/39270] New: Explicit instantiation rejected
Hello.
The following does not compile:
-
class A
{
public:
class B {};
template class T, class X void x(X a) {}
template class T void x(int a);
};
template class T
void A::x (int a)
{ }
template void A::xA::B (int a);
--
Namely, the explicit instantiation on the last line is rejected with the error:
test.cc:13: error: ambiguous template specialization xA::B for void
A::x(int)
i.e. not even recognized as an explicit instantiation.
Implicit instantiation seems to work fine.
cheers

[Bug c++/39271] New: 64 bit memory allocation possible error
Subject: Possible error with C++ compilers on 64 bit PC running
SUSE 10.3 with memory allocation
In C++ you can request space with the new command but if you
repeatedly do this then it should eventually fail. The following
program is designed to illustrate this by first repeatedly asking
for 1Mbyte until the requests fails. This is then done again
with blocks of double the size etc.
On 32 bit PCs the program behaves as expected and the output
is shown below. However on a 64 bit PC with g++ version 4.2.1
and with the Sun linux compiler CC and with the intel compiler
icc no failure is ever reported. This suggests a serious bug
in some aspect of the 64 bit system or have I made a mistake
myself?
The 64 bit PC with 4GB of RAM often runs very slowly and is
sometimes the slowest PC that I have had for many years with
many of the applications that I regularly run.
Could the above be the reason for the PC sometimes being so slow?
Any help in resolving the bug with the 64 bit system will be
appreciated. My only solution at the moment is abandon the
use of the 64 bit operating system in favour of the 32 bit
version.
..c++ program err64.cpp follows
#include iostream
#include iomanip
using namespace std;
int main()
{
char *c;
char *a[11][8192];
int b[11];
int i, j, k, m=1024*1024;
// .. request m bytes until the request fails
for(j=0; j11; j++)
{
for(i=0; i8192; i++)
{
c=new (nothrow) char[m];
if(c==NULL)break;
a[j][i]=c;
}
// .. release the space
for(k=0; ki k8192; k++)delete[] a[j][k];
b[j]=i;
cout setw(3) j
m= setw(12) m
b[j]= setw(8) b[j];
if(i=2) cout pointer difference=
setw(12) a[j][i-2] -a[j][i-1];
cout endl;
// .. double m for the next attempt
m=2*m;
}
return 0;
}
..end of program
output of g++ -v follows
