[Bug tree-optimization/31873] New: missed optimization: we don't move "invariant casts" out of loops
This PR was originally opened against PRE (PR25809), but turns out PRE can't solve this problem, so here's a new PR instead: In testcases that have reduction, like gcc.dg/vect/vect-reduc-2char.c and gcc.dg/vect-reduc-2short.c, the following casts appear: signed char sdiff; unsigned char ux, udiff; sdiff_0 = ... loop: # sdiff_41 = PHI ; . ux_36 = udiff_37 = (unsigned char) sdiff_41; udiff_38 = x_36 + udiff_37; sdiff_39 = (signed char) udiff_38; end_loop although these casts could be taken out of loop all together. i.e., transform the code into something like the following: signed char sdiff; unsigned char ux, udiff; sdiff_0 = ... udiff_1 = (unsigned char) sdiff_0; loop: # udiff_3 = PHI ; . ux_36 = udiff_2 = ux_36 + udiff_3; end_loop sdiff_39 = (signed char) udiff_2; see this discussion thread: http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01827.html -- Summary: missed optimization: we don't move "invariant casts" out of loops Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dorit at il dot ibm dot com GCC host triplet: powerpc64-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31873

Some form of DCE a little more delicate than this will be necessary to fix this

That was the answer I was looking for. Sounds like the > vectorizer is biting off more than it can chew :) Perhaps there is a > check missing for chrecs somewhere. Yes, I also think that the quick fix is to add to the vectorizer the missing checks for simple enough expressions. I went back to look at the testcase, and I saw these nested loops, and we are trying to vectorize the innermost ones. So for avoiding a failed vectorization, and making the vectorizer to produce the right code, we want to generate some code for the base address in the outer loop.

[Bug middle-end/31738] Fortran dot product vectorization is restricted

--- Comment #7 from jakub at gcc dot gnu dot org 2007-05-08 19:08 ---
This really is not specific to OpenMP, I believe the following is valid
threaded program:
#define _XOPEN_SOURCE 600
#include
#include
int v;
pthread_mutex_t m = PTHREAD_MUTEX_INITIALIZER;
pthread_barrier_t b;
void
foo (int x, int y)
{
int i;
for (i = 0; i < 100; i++)
{
if (i > x)
v = y;
}
}
void *
tf (void *arg)
{
pthread_barrier_wait (&b);
if (arg == NULL)
{
pthread_mutex_lock (&m);
if (v != 0)
abort ();
foo (50, 10);
pthread_mutex_unlock (&m);
pthread_barrier_wait (&b);
foo (120, 30);
}
else
{
foo (100, 20);
pthread_barrier_wait (&b);
pthread_mutex_lock (&m);
if (v != 10)
abort ();
foo (80, 40);
if (v != 40)
abort ();
pthread_mutex_unlock (&m);
}
return NULL;
}
int
main (void)
{
pthread_t th[2];
pthread_barrier_init (&b, NULL, 2);
if (pthread_create (&th[0], NULL, tf, NULL)
|| pthread_create (&th[1], NULL, tf, (void *) 1L))
return 1;
pthread_join (th[0], NULL);
pthread_join (th[1], NULL);
return 0;
}
and at -O0 works just fine and has no races in it, it is quite easy to show
the shared variable is only ever read or written inside of the critical
section.
But loop IM creates a race even when there is none in the code originally, if I
compile this with -O2 (both 4.1.x and trunk) it will abort after a couple of
attempts.
That's why I think we should have a generic option that disables optimizations
which are safe only in sequential programs (and -fopenmp would imply that
option).

You misunderstand my point: the international C++ standard quite clearly specifies under what circumstances a program is what it calls "ill-formed" and when a compiler has to issue an error. Taking the address of a temporary is completely valid according to this standard (i.e. it conforms to the *syntax* of the C++ language), and consequently a compiler can't issue an error. The fact that the program does something you may not expect, i.e. that the *semantics* are not what you want, is an entirely different matter. In this case, the C++ standard says that the behavior of your program is undefined. Compilers may warn about this, but they may not issue an error.

Exactly > because > of this issues. No. This is wrong. The model simply requires the compiler to be smarter. Sequential compilers are not aware of parallel semantics. If the compiler was thread-aware, these issues would be transparent to the user (as they should be). The original code did not have a race condition. The compiler transformations introduced a race-condition. This *is* a compiler bug. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31862

The real solution is, unfortunately, quite a bit of work. In the meantime, we should probably annotate the shared variables and consider them volatile. This should prevent most optimizers from messing things up inadvertently. This should be done within OMP regions. Orphaned functions may become a problem, so this should be implemented as an IPA pass. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31862
