--- Comment #22 from rakdver at gcc dot gnu dot org 2006-05-02 07:56 --- (In reply to comment #14) Hmm, I wonder if the following loop in scev_probably_wraps_p is wrong. estimate_numbers_of_iterations_loop (loop); for (bound = loop-bounds; bound; bound = bound-next) if (proved_non_wrapping_p (at_stmt, bound, type, valid_niter)) return false; it says that if one bounds does not wrap, then all variables asked about don't which is not true. this piece of code seems OK to me (modulo that proved_non_wrapping_p was quite missleading way to name that function). What it does is that we know that the loop is executed at most BOUND times, and that the variable will not wrap for at least VALID_NITER iterations; therefore, if we are able to prove that VALID_NITER BOUND for any of the bounds, we know that the variable does not wrap. There is probaby off-by-one error in one of the functions. -- rakdver at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |rakdver at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED Last reconfirmed|2006-04-11 23:17:57 |2006-05-02 07:56:20 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26304

Fixed on 4.1 and 4.2
Thanks for fixing :-)
Still it would be nice if it would be detected during compile time. In
my case it was burried in an
if(something that rarely happens) write(*,'(''n'')') n
which I wouldn't have found easily without the compile-time warning of
the NAG compiler.

[Bug libgcj/27352] SecurityManager.checkPermission() called unnecessarily
--- Comment #4 from aph at gcc dot gnu dot org 2006-05-02 10:08 --- The real reason is that we want the actual caller of SecurityManager.checkPermission(), but we're walking up the stack to the user code that called Class.newInstance() Class.getMethod(). This problem is as far as I'm aware unique to gcj, but it might be worth testing on other VMs. I have a patch for this that I'm testing. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27352

[Bug target/27386] New: AVR: wrong code generated when passing three uint64_t arguments to function
When passing three uint64_t arguments to a function, AVR-GCC generates completely wrong code. The first two uint64_t arguments are passed in registers, and thus not affected. The caller then allocates 8 bytes on the stack for the fourth argument, but writes to 8 bytes beyond the allocated area (destroying the current function's stack). The callee tries to fetch the values from the locations on the stack where they ought to be (but actually aren't). This bug appears in all tested versions of GCC (3.4.6, 4.1.0, SVN trunk). -- Summary: AVR: wrong code generated when passing three uint64_t arguments to function Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: critical Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: j at uriah dot heep dot sax dot de GCC build triplet: *-*-* GCC host triplet: *-*-* GCC target triplet: avr-*-* http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27386

[Bug middle-end/27388] New: omp_is_private issues
void
foo (void)
{
int i;
i = 0;
#pragma omp parallel shared (i)
{
#pragma omp master
i++;
#pragma omp parallel for
for (i = 0; i 10; i++)
;
}
}
results in very weird omplower dump:
1) #pragma omp parallel shared(iD.1922) private(iD.1922)
for the outer parallel
(surely we don't want i being shared and private at the same time,
just shared here)
2) #pragma omp parallel shared(iD.1922)
for the inner parallel - in this case i certainly ought to be private,
not shared
I think 1) is caused by n-value = GOVD_PRIVATE; messing up outer context,
while 2) probably because omp_is_private shouldn't recurse over is_parallel
contexts.

[Bug tree-optimization/27381] [4.2 Regression] ice on valid code with -O
--- Comment #5 from amacleod at redhat dot com 2006-05-02 15:38 --- The assert condition is not flawed. It has exposed a second bug with the old immuse iterator scheme that was also hidden by the old algorithm work around Jeff had implemented. When iterating over the immediate uses, and deleting a stmt (such as a conditional) causes an edge to be removed, PHI nodes have an argument deleted. when we remove PHI arguments, we move the last phi argument to whatever position we actually deleted, and reduce the argument count. When arguments are moved, they were simply being delinked and then linked back into the use chain. In this particular example, the argument being moved was another occurence of the ssa_name being iterated over, and by delinking it and linking it back in, it was moved back to the beginning of the immuse list. This caused it to be missed during the iteration pahse, and rightfully triggered the assert. The fix is to simply keep the same linked position when the argument is moved instead of removing it from the list and linking it back in. Patch is currently being tested.
