[Bug ada/26678] GNAT BUG DETECTED when compiling AWS.
--- Comment #10 from matz at suse dot de 2006-05-03 15:40 ---
We also got a bugreport about an ICE in get_constraint_for_component_ref,
but have a C testcase. In the hope that it's the same reason I paste it
here:
-
/* compile with gcc -c -O2 -o foo.o foo.c */
typedef struct {
struct { } z;
} thang_t;
struct widget {
struct widget *p, *q;
};
typedef struct thing {
struct widget x;
} thing_t;
struct {
int a;
int b;
int c;
int d;
int e;
thang_t f;
thing_t g;
} my_struct;
static void foo(thang_t *r)
{ splat(r);}
void function(int blaz)
{ foo(my_struct.f);}
--
This fails with 4.1.x on x86_64 with -O1 and beyond.

--- Comment #1 from charlet at gcc dot gnu dot org 2006-03-14 13:38 --- Well, if it's CVS HEAD, it's not a release. Anyway, please post self contained (reduced if possible) sources showing the problem, as well as standalone command line (simplified if possible). Thanks.

--- Comment #3 from charlet at gcc dot gnu dot org 2006-03-14 13:52 --- Thanks for the sources. If you get a chance to reduce the problem, that will certainly give this report higher priority. I am also surprised by the location: tree-ssa-structalias.c, I thought strict aliasing was disabled for Ada. Are you using FSF GCC sources or sources modified ? (btw, is there a way to remove the 'waiting' state without confirming the PR ?) Arno -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26678

--- Comment #4 from krischik at users dot sourceforge dot net 2006-03-14 14:02 --- Hi Arnaud, The HEAD is indeed a typo - should have been release_2_1a. For head we have a different problem (bug:26162). As for the compiler, it is the unmodified release version: GNAT 4.1.0 gcc (GCC) 4.1.0 With Regards Martin -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26678

Are you using FSF GCC sources or sources modified ? Structure aliasing is indeed disabled for Ada but tree-ssa-structalias.c contains the generic points-to analyser, aka constraint solver. -- ebotcazou at gcc dot gnu dot org changed: What|Removed |Added CC||ebotcazou at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26678

--- Comment #6 from pinskia at gcc dot gnu dot org 2006-03-14 14:53 --- A note is that it works on x86_64 (and I cannot test i686 because Ada does not have mulitilib support:( ). if Ada did have multilib support I could reduce this easier. -- pinskia at gcc dot gnu dot org changed: What|Removed |Added CC||pinskia at gcc dot gnu dot ||org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26678
