[Bug fortran/22519] New: Memory and binary disk layout disagree for real*10
The memory layout of a real*10 variable on an i386 processor requires 12 or 16 bytes per variable, depending on the flag -m128bit-long-double. The disk layout for unformatted (binary) writing occupies 10 bytes per variable. This has several disadvantages. It is different from I would naively expect (which does not mean much), and it is different from binary C I/O (which could also be ignored). However, it is likely also rather inefficient if large arrays are written to disk, because a single call to write() or fwrite() now has to be split up into one call per array element, so that the padding is removed. It is also questionable whether having a real*10 variable occupy 12 or 16 bytes in memory is what people expect; again, this could be ignored since the standard permits this. However, this is also very different from what other compilers do. -- Summary: Memory and binary disk layout disagree for real*10 Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: schnetter at aei dot mpg dot de CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22519
[Bug c++/22520] New: g++ treats object declaration as function declaration (rejects valid program)
This is actually applicable to every version of g++ I have on my system, not
just 4.0.1. I am tempted to say I have it wrong, but the only difference between
the two object declarations is how a constant is expressed.
g++ treats these two object declarations as different:
Angle angle1( Degrees(180.0));// an instance of Angle
Angle angle2( Degrees(OneEighty));// declaration of a func??
where
const double OneEighty = 180.0;
The following line is rejected because angle2 isn't an instance of Angle, but is
being treated as a function declaration, incorrectly, I think:
angle1 += angle2; // won't compile because angle2 isn't an Angle
The whole program follows:
///start
const double OneEighty = 180.0;
struct Degrees
{
double m_Degrees;
Degrees( const double degrees )
:
m_Degrees( degrees )
{
}
};
struct Angle
{
double m_Degrees;
Angle(const Degrees degree)
:
m_Degrees( degree.m_Degrees )
{
}
Angle operator+=(const Angle rhs)
{
m_Degrees += rhs.m_Degrees;
return *this;
}
};
void test(void)
{
Angle angle1( Degrees(180.0));// an instance of Angle
Angle angle2( Degrees(OneEighty));// declaration of a func??
//
// The following line fails
// on the compilers on my system of the following versions:
// gcc version 2.96 2731 (Red Hat Linux 7.3 2.96-126)
// gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)
// gcc version 3.4.0 (Red Hat Linux 3.4.0-1)
// gcc version 4.0.0
// gcc version 4.0.1 20050617 (prerelease)
//
angle1 += angle2; // won't compile because angle2 isn't an Angle
//
// The following two types from typeid are not equal
//
// printf(typeid(angle1).name() = \%s\\n,

[Bug other/22368] [meta-bugs] mis-match types in GCC
--- Additional Comments From pinskia at gcc dot gnu dot org 2005-07-17
17:33 ---
Note the comparisions patch because of the way gimple removes casts to void*
gets:
int f(int *a, char*b)
{
return ((void*)a) == ((void*)b);
}
wrong.
The following is also effected:
g++.dg/abi/vbase13.C:
g++.dg/expr/cond1.C
g++.old-deja/g++.abi/primary.C
I have to figure out how to handle that. Maybe in
tree_ssa_useless_type_conversion_1 remove the
special case for void*.

The gimplifier needs to split this into a new static temporary, there's
no way we can do something sane with ADDR_EXPR CONSTRUCTOR.

I don't think the timing issue is valid.
Look at these benchmarks:
The first one simulates copying 12-byte values to 10-bit values,
the second one a compact memcpy of a larger field.
$ cat foo.c
#include string.h
#define NELEM 1000
#define SA 12
#define SB 10
void foo(char *a, char *b, int n);
int main()
{
char *a, *b;
int n;
a = malloc(NELEM*SA);
b = malloc(NELEM*SB);
for (n=0; n10; n++)
foo(a,b,NELEM);
return 0;
}
void foo(char *a, char *b, int n)
{
int i;
for (i=0; in; i++)
{
memcpy(a, b, 10);
a += SA;
b += SB;
}
}
$ gcc -O3 foo.c

a = malloc(NELEM*SA);
b = malloc(NELEM*SA);
for (n=0; n10; n++)
memcpy(a, b, NELEM*SA);
return 0;
}
$ gcc foo2.c
foo2.c: In function 'main':

of course.

--- Additional Comments From schnetter at uni-tuebingen dot de 2005-07-17 20:01 --- My argument -- which I had in my head, but didn't put down -- went as follows: ultimately, things have to be written by a system call, and a system call is expensive. (One system call per array element is out of the question.) Thus we either dump the whole array to disk, byte for byte as it is in memory, or we have to transform it into a temporary buffer and then write this buffer. C's fwrite uses a buffer (probably), fprintf does for sure. If you remove the padding, then you have to allocate and deallocate these buffers and pack or unpack the array elements explicitly. Depending on your I/O library, that may be a lot of work. And in the end you are still incompatibly to C. (I'm afraid we may be going to repeat a discussion here that was already held on the mailing list.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=22519

address of C99 struct in static variable in function
On Sun, 17 Jul 2005, pinskia at gcc dot gnu dot org wrote:
Take the following code:
struct f1
{
int i;
};
void f(void)
{
static struct f1 *f2 = (struct f1){1};
}
This is valid C99 at least according to both ICC and Comeau.
So report it as a bug in ICC and Comeau. It is exactly as valid as
struct f1
{
int i;
};
void f(void)
{
struct f1 tmp = { 1 };
static struct f1 *f2 = tmp;
}
i.e. not at all. The address of an object of automatic storage duration
is not a constant.

[Bug tree-optimization/22538] New: Eustore does not remove stores for struct assignments
Take the following code:
typedef struct dw_cfi_oprnd_struct {
unsigned long reg;
} dw_cfa_location;
dw_cfa_location loc;
void def_cfa_1 (void) {
loc.reg = loc.reg;
}
We don't remove the store/load to loc.rec on the tree level. We even don't
remove PIC startup code for
ppc-darwin either:
_def_cfa_1:
mflr r0
stw r31,-4(r1)
lwz r31,-4(r1)
mtlr r0
blr
