Looks like a strength reduction bug.
Smaller self-contained testcase:
extern void abort (void);
typedef struct { int a; char b[3]; } S;
S c = { 2, aa }, d = { 2, aa };
void *
bar (const void *x, int y, int z)
{
return (void *) 0;
}
int
foo (S *x, S *y)
{
const char *e, *f, *g;
int h;
h = y-a;
f = y-b;
e = x-b;
if (h == 1)
return bar (e, *f, x-a) != 0;
g = e + x-a - h;
while (e = g)
{
const char *t = e + 1;
if (__builtin_memcmp (e, f, h) == 0)
return 1;
e = t;
}
return 0;
}
int
main (void)

[Bug c++/20099] -pthreads should imply -fno-threadsafe-statics
--- Additional Comments From gniccolai at yahoo dot com 2005-02-22 10:27 --- You say a hypothetical multithreaded C++ should state this as the semantics for static locals, and I don't disagree with you, provided we are not talking about one based on POSIX threads. POSIX specifically made the design decision to always require explicit locks and to always require the programmer to find, document, and lock cases where concurrent accesses might occur. I think I wrote a rationale that explains and justifies this choice at http://www.niccolai.ws/works/articoli/art-multithreading-en-1a.html I had not been able to find an official rationale from open group; the nearest thing seems to be: http://www.unix.org/whitepapers/reentrant.html If more precise and authoritative ones are available, please point them out. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20099

[Bug c++/20140] New: template function complains about char-array initialized from wide string
Hello,
this is my code:
templatetypename T void foo() {
unsigned char s[] = ;
(void)s;
}
int main() {
/* removing either of the calls below makes the error disappear */
fooint();
foochar();
}
Compiling this program with g++[0] results in
try.cc: In function `void foo() [with T = char]':
try.cc:9: instantiated from here
try.cc:2: error: char-array initialized from wide string
I think this is wrong because isn't a wide string. The error disappears
when I remove unsigned from the declaration of s, or when only a single
fooT is instantiated. The actual types don't matter; my original code
used function pointers.
HTH, Lukas

For pure calls the code would need to invalidate all recorded pure calls whenever a stmt might modify global state.

If we changed the function in comment #0 like so:

Fold should do this simplification.

The failure is here:
package org.eclipse.jdt.internal.compiler.impl;
public class CompilerOptions ...
{
void updateSeverity(long irritant, Object severityString) {
if (ERROR.equals(severityString)) {
this.errorThreshold |= irritant;
and the corresponding bytecode is:
Method name:updateSeverity Signature: (long,java.lang.Object)void
Attribute Code, length:208, max_stack:7, max_locals:4, code_length:110
0: ldc String error
2: aload_3
3: invokevirtual Method java.lang.String.equals (java.lang.Object)boolean
The aload_3 looks wrong to me.
So, there are two separate issues:
1. Why was aload_3 generated? Which compiler genrated it?
2. How did this get past the libgcj verifier?
tromey added to CC list to investigate the verifier.
overholt, please let me know how this jar file was generated.
Bug upgraded to critical.

[Bug bootstrap/20143] New: 4.0 bootstrap unreasonably requires 64-bit target type mode support.
Although I don't believe this is a regression, I do believe it's a bug which should ideally be remedied as soon as reasonably possible; as it seems unreasonable to require any target to support data types more than twice as large as it's pointer type, or required by the language standards; so feel that this should be considered a reasonably important failure to remedy. To demonstrate this bug, simply reduce the defined long long size in avr.h to the size of a long which is defined as being 32-bits; resulting in: In file included from /Applications/avr/avr-src/gcc/unwind-dw2.c:36: /Applications/avr/avr-src/gcc/unwind.h:59: error: unable to emulate 'DI' In file included from /Applications/avr/avr-src/gcc/unwind-dw2.c:40: /Applications/avr/avr-src/gcc/unwind-pe.h: In function 'read_encoded_value_with_base': /Applications/avr/avr-src/gcc/unwind-pe.h:191: error: unable to emulate 'DI' /Applications/avr/avr-src/gcc/unwind-pe.h:194: error: unable to emulate 'DI' make[2]: *** [libgcc/./unwind-dw2.o] Error 1 -- Summary: 4.0 bootstrap unreasonably requires 64-bit target type mode support.

The SUBREG is SUBREG_PROMOTED_VAR_P and SUBREG_PROMOTED_UNSIGNED_P, which is a promise that the upper 32 bits are all 0. The problem is that when using the KR style function definition, there is no prototype for the function and so the caller expects int exact_log2_wide (int); while the callee is actually int exact_log2_wide (unsigned int); It looks like int is passed sign extended and unsigned int zero extended, so the functions disagree about what the upper 32 bits of the argument should contain. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20134

[Bug c++/20142] implicity assignment with multi-dimensionnal array members
--- Additional Comments From reichelt at gcc dot gnu dot org 2005-02-22

Here's a slightly reduced testcase.
===
#includestdio.h
struct A
{
A() : i() {}
A (const A);
~A()
{
printf (Destructor: i = %d\n, i);
}
A operator= (const A a)
{
static int count=0;
i = a.i + 1;
printf (Assignment %d\n, ++count);
return *this;
}
int i;
};
struct B
{
A x[2][2];
};
int main()
{
B b;
b = b;
}
===
With versions prior to gcc 3.3 we get the output
Assignment 1
Assignment 2
Assignment 3
Assignment 4
Destructor: i = 1
Destructor: i = 1
Destructor: i = 1
Destructor: i = 1
With gcc 3.3 and later we get
Destructor: i = 0
Destructor: i = 0
Destructor: i = 0
Destructor: i = 0

--- Additional Comments From jakub at gcc dot gnu dot org 2005-02-22 18:14 --- The testcase is indeed invalid. KR definition can't serve as a prototype and whether a 32-bit argument is on PPC64 sign or zero extended to 64-bit depends on whether the argument is signed or unsigned. So, either prototypes must be used, or the caller must match the type of the arguments. if (exact_log2_wide (0x8000) != 31) abort (); or if (exact_log2_wide ((unsigned int) -2147483648) != 31) abort (); work just fine. On many 64-bit arches this testcase will work anyway, as arguments are e.g. always sign extended to 64-bit (I believe Alpha is an example here) or zero extended to 64-bit. -- What|Removed |Added Status|NEW |RESOLVED Keywords|wrong-code | Resolution||INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20134
