Hello,
as discussed in http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01133.html,
it might be a good idea to try moving cfg to alloc pools. The patch
below does that for basic blocks (each function has a separate pool
from that its basic blocks are allocated). At the moment, the patch
breaks
Is there anyone interested in i586-pc-interix3 (Interix 3.x)
configuration improvements? I have just started a little work to update
the configuration for recent GCC versions. If you have any interests,
please let me know.

I would like to use some sort of hashing to speed up searching for an

So, the most obvious answer to these points is that arithmetic is
always performed in a type where TYPE_MIN/MAX_VALUE is

Right. In the Ada case, that's required by the language anyway.

And here is a testcase which makes this reproduciable on the trunk (on
powerpc-linux):
extern void abort (void);
extern void exit (int);
_Bool a;
int foo ()
{
int b;
int c = a;
c = __builtin_abs(c);
c =

The following simplified testcase still crashes on mainline when compiled
with -O2:
==
struct A
{
int i, *p;
A* a;
void foo()
{
if (p)
p++;
else
{
if
The following code snippet triggers a segfault since GCC 3.4.0:
===
struct A
{
A();
void operator delete(void*,...);
};
void foo()
{
new A;
}

I have looked into this bug and I think it is an HP math lib bug. The 64 bit
powf function is using %fr12R but not saving/restoring it the way it is
supposed to. I have a query in to the math lib folks to see if they

Although PR18923 is fixed now, this testcase (from comment#7) is still
crashing.

Here are the test results. I enabled almost every possible option and all the
checking that is functional. Nearly every test passed. I diffed it with a
result from a few days ago (before the mod), I do not seem to have
