[Bug debug/43119] debug info vs. scheduling

[aoliva at gcc dot gnu dot org]

--- Comment #2 from aoliva at gcc dot gnu dot org  2010-06-02 06:43 ---
My mid-term vision to address this sort of problem does not involve adding more
debug bind insns (I don't quite see how to get them right), but rather emit a
new kind of debug stmt/insn so as to emit is_stmt notes in lineno, so we can
set breakpoints at the right spot for line 19, rather than at the moved-ahead
insns, avoiding all the bouncing back-and-forth when stepping in optimized
programs.  I ought to go ahead and implement this one of these days.

[Bug debug/43222] two DEBUG i => 0 generated after loop copy header

[aoliva at gcc dot gnu dot org]

--- Comment #6 from aoliva at gcc dot gnu dot org  2010-06-02 06:28 ---
Andrew, the debug stmts are indeed originally from the loop header's PHI nodes.
Before ch we have:

i_1 = ;
# i => i_1
goto ;

:
i_3 = (i_2);
# i => i_3

:
i_2 = PHI ;
# i => i_2
if () goto ; else goto ;

copy_loop_header turns this into:

i_1 = ;
# i => i_1

:
i_4 = PHI ;
# i => i_4
if () goto ; else goto ;

:
i_3 = (i_2);
# i => i_3

:
i_2 = PHI ;
# i => i_2
if () goto ; else goto ;

and that's correct.  Then cfgcleanup realizes the headers can be merged with
their preds, and that kills the PHI nodes, but there's no reason why this
should kill the debug stmts.

Of course we could arrange for some cleanup passes to detect and remove debug
stmts in case they become redundant, but I don't see that we have a bug here.

The debug info machinery is doing the best it can given the behavior of
reassoc, so I'm stepping away from this bug.  Getting reassoc to generate stmts
at a different place may have improvement of debug info as a side effect, but
I'll leave that to someone more familiar with reassoc.

Some additional tests/results:

Because we are using gfc_match_init_expr: leaving the ; out.

pr44371.f90:5.18:

  if (c=='y') stop if (c=='Y') stop
  1
Error: Function 'if' in initialization expression at (1) must be an intrinsic
function

This makes no sense in the context, so I want to change the above error
message.

The following message is given after I fix the eos match issue:

  if (c=='y') stop 123 if (c=='Y') stop
  1
Error: Syntax error in STOP statement at (1)

Simply deleting the match_eos leaves the invalid undetected.

I plan to commit the following as simple and obvious. Sorry for the breakage.

Removing this chunk of code causes no testsuite regressions
on x86_64-*-freebsd.

Is leftover from the STOP/ALL_STOP churn?

[kargl at gcc dot gnu dot org]

--- Comment #1 from kargl at gcc dot gnu dot org  2010-06-02 00:42 ---
The problem is caused by gfc_match_stopcode().


  if (gfc_match_eos () != MATCH_YES)
{
  m = gfc_match_init_expr (&e);
  if (m == MATCH_ERROR)
goto cleanup;
  if (m == MATCH_NO)
goto syntax;
}
#if 0
  if (gfc_match_eos () != MATCH_YES)
goto syntax;
#endif

If the first gfc_match_eos () does not match an end-of-statement,
gfortran immediate calls gfc_match_eos () again.  With the #if 0
above the code in comment #1 compiles and executes.  So, why is
there a 2nd call to gfc_match_eos().

[Bug fortran/44371] New: [4.6 Regression] STOP parsing rejects valid code

[burnus at gcc dot gnu dot org]

Found at
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/b2e1f15014d76daf

There, Al Greynolds reports that the following program fails to compile with:

  if (c=='y') stop; if (c=='Y') stop
   1
Error: Syntax error in STOP statement at (1)


I assume it is due to the new expression parsing for (ALL) STOP, which gets
confused if no expression is matched because of a semicolon rather than because
of EOL.


  character(1) c
  read(*,*) c
  if (c=='y') stop; if (c=='Y') stop
  end

I'd vote to reject it for any -std=*. This extension just asks for trouble.

[Bug middle-end/44297] Big spec cpu2006 prefetch regressions on gcc 4.6 on x86

+ }

The patch should fix the tonto regression caused by non-constant step
prefetching. It is just that you should move the computation and comparison
outside  (before) the loop and the debug dump after the loop.

I am just thinking that for such loop, we should do nothing: non-non-temporal
stores and no constant step prefetching because nothing could be trusted.

I am doing some experiemnts and let you know what I could find. Thanks.

Hi, Christian:

For constant step prefetching only, tonto regressed by ~7%, and for const +
invariant step prefetching combined, it regressed by ~16%.

I should have mentioned earlier that non-constant step prefetching has improved
459.GemsFDTD by 4~5% on amd-linux64 systems, and tonto regression by
non-constant step prefetching should be able to be fixed by re-compute the
prefetch count by considering the unroll_factor. However, I have found the 
non-temporal store problem which can cause 416.gamess degradation by ~50%.
I am not sure whether it is caused by non-constant step prefetching or not.

When you use -mtune=native, please include output from "gcc -v ..."
to show real tune target passed to cc1. Otherwise, people will have
a hard time to reproduce your problem since their native machines may
be very different from yours.

[Bug c++/44366] New: g++ crashes when declaring a lambda expression using a typedef'd decltype.

[LindleyF at gmail dot com]

In the minimal example (to be attached), g++ crashes with a "please submit bug
report" message.

The goal of the original code was to provide a generic multi-label connected
component algorithm. Therefore, I wished to output a label along with each
Component of the same type as the input data 2d arraydecltype(data[0][0]).

However, when I added a lambda expression as part of operating on something
related to this type, g++ began crashing during compile.

I realize that in some cases decltype(data[0][0]) may have a reference type so
this code may be invalid; however, the compiler still should not crash, but
simply report an error.

[Bug fortran/44360] wrong-code: host-associated procedure wrongly favoured to use-associated one

[burnus at gcc dot gnu dot org]

--- Comment #3 from burnus at gcc dot gnu dot org  2010-06-01 14:01 ---
The issue seems to be parse.c's gfc_fixup_sibling_symbols - the the following
seems to exclude (use-associated) module variables and (use-associated)
functions from being fixed up:

&& !(old_sym->attr.external
  || (old_sym->ts.type != BT_UNKNOWN
&& !old_sym->attr.implicit_type)

Maybe one should check for use-association here?
That is:  || old_sym->attr.use_assoc.

More complete testcase:
/* { dg-options "-Wunused" } */
/* { dg-do compile } */

int
f1 (int u, int v)
{
  int a, b, c, d, e, f, g, h, i;
  a = u;
  b = v;
  c = u;
  d = v;
  e = u;
  f = v;
  g = u == 6 ? a : b;
  h = 0 ? c : d;
  i = 1 ? e : f;
  return g + h + i;
}

No warnings with C, two warnings with C++, apparently because
build_conditional_expr folds the created COND_EXPR before it has been marked.

Another testcase, again, no set but not used warnings in C but some in C++.
/* { dg-options "-Wunused" } */
/* { dg-do compile } */

void
f1 (int u, int v)
{
  int a, b, c, d, e, f;
  a = u;
  b = v;
  c = u;
  d = v;
  e = u;
  f = v;
  u == 6 ? a : b; /* { dg-warning "no effect" } */
  0 ? c : d; /* { dg-warning "no effect" } */
  1 ? e : f; /* { dg-warning "no effect" } */

[Bug rtl-optimization/44364] New: Wrong code with e500 double floating point

[gcc at breakpoint dot cc]

The testcase (which is stripped down perl code) attached compiled with:
gcc -fPIC -fno-strict-aliasing -pipe \
 -O2 \
 -g -o tc-lossings-floats tc-lossings-floats.c -Wall -mno-isel

results in after executing:
|RESET: 252.00 | 0.00
|RESET: 504.00 | 252.00
|RESET: 756.00 | 504.00
|RESET: 1008.00 | 756.00
|RESET: 1260.00 | 1008.00
|RESET: 1512.00 | 1260.00
|RESET: 1764.00 | 1512.00
|RESET: 2016.00 | 1764.00
|RESET: 2268.00 | 2016.00
 => 2268.00
|RESET: 2520.00 | 0.00
|RESET: 2772.00 | 2520.00

With -O1 instead -O2:
|RESET: 252.00 | 0.00
|RESET: 504.00 | 252.00
|RESET: 756.00 | 504.00
|RESET: 1008.00 | 756.00
|RESET: 1260.00 | 1008.00
|RESET: 1512.00 | 1260.00
|RESET: 1764.00 | 1512.00
|RESET: 2016.00 | 1764.00
|RESET: 2268.00 | 2016.00
 => 2268.00
|RESET: 2520.00 | 2268.00
|RESET: 2772.00 | 2520.00

The "=>" line sets the the second value in the "|RESET" line. With -O1 is
remains where it is, with -O2 it gets overwritten. The original perl code gets
here a totally random values. 

Now. It is getting better. The source compiled with -S and the resulting
assembly file assembled with gcc-4.3 does not show this problem. After diffing
of the two resulting binaries I saw  a difference in __floatdidf() which is
called from Kino_OutStream_tell(). The variant which is attached by the 4.3
compiler does not use floating point instead it uses integer code which calls
other functions (__floatsidf, __muldf3, __floatunsidf, __adddf3) which use also
interger code. The 4.3 compiler was not compiled with --enable-e500_double. 

So after looking at the code I saw now the following:
1c24 <__floatdidf>:
1c6c:   11 23 1a 2c evmergehi r9,r3,r3

This function is touching the complete 64bit r9 register
The code which calls it:

1a40:   91 21 00 20 stw r9,32(r1)
1a44:   4e 80 04 21 bctrl   # tell function which in turn calls
floatdidf

1a7c:   81 21 00 20 lwz r9,32(r1)
1a80:   38 60 00 00 li  r3,0
1a84:   7e 33 8b 78 mr  r19,r17 
1a88:   12 49 92 e1 efdsub  r18,r9,r18
1a8c:   10 80 92 fa efdctsiz r4,r18
1a90:   12 49 4a 17 evmrr18,r9  

So we just save the lower 32bit of r9 before calling the function and the upper
32bit are overwritten by efdsub.

[Bug fortran/44360] wrong-code: host-associated procedure wrongly favoured to use-associated one

[burnus at gcc dot gnu dot org]

--- Comment #2 from burnus at gcc dot gnu dot org  2010-06-01 12:44 ---
Some debugging shows that at least for
  gfc_match_call
the correct symtree is picked up via gfc_get_ha_sym_tree and saved into
new_st.symtree (tested via: attr.use_assoc == 1 and formal->sym->name == pvec).


However, the search is thrown over in resolve_call:
  if (csym && gfc_current_ns->parent && csym->ns != gfc_current_ns)
  gfc_find_sym_tree (csym->name, gfc_current_ns, 1, &st);
  And this finds the wrong sym.

... Actually, that's incomplete - already c->symtree->n.sym has the wrong
symbol?!?

In case  of functions/variables, it seems to go through check_host_association
- which somehow avoids this problem (cf. below).

 * * *

As the following test case shows, only use-associated SUBROUTINES are
mishandled, use-associated module variables and use-associated FUNCTIONS are
handled correctly:

! { dg-do run }
!
! PR fortran/44360
!
module m
  integer :: var = 43
contains
 integer function fun()
   fun = 42
 end function fun
 subroutine fun2()
   print *, 'OK'
 end subroutine fun2
end module m

module m2
  integer :: var = -2 ! OK, never accessed
contains
 subroutine test()
   use m
   call fun2()! Calls ABORT()
   if (fun() /= 42) call abort()  ! OK
   if (var /= 43) call abort()! OK
 end subroutine test
 integer function fun()
   call abort() ! OK, never called
   fun = -3  
 end function fun
 subroutine fun2()
   call abort()  ! <<< Should not be called but is
 end subroutine fun2
end module m2

use m2
call test()
end
! { dg-final { cleanup-modules "m m2" } }

This appears to crash at the same point every time which I think rules out HW
error to me.

The following command compiles successfully:
gcc46 -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -I.
-I"/dta/ports/multimedia/ffmpeg/work/ffmpeg-0.5.2" -pipe -O3

-Wtype-limits -Wundef -O0 -c -o libavutil/crc.o libavutil/crc.c 

Note -O0 and removal of all -f* flags. I don't know exactly which flags I could
add and have it still compile.

[Bug c++/44362] New: Bogus set-but-not-used warning

[rguenth at gcc dot gnu dot org]

#define WORDS_BIG_ENDIAN 0
int foo(int x, int y)
{
  int a = x;
  int b = y;
  int j = WORDS_BIG_ENDIAN ? a : b;
  return j;
}

which actually breaks bootstrap with C++.

[Bug fortran/44360] wrong-code: host-associated procedure wrongly favoured to use-associated one

[burnus at gcc dot gnu dot org]

--- Comment #1 from burnus at gcc dot gnu dot org  2010-06-01 10:09 ---
CONFIRMED. Old bug - dating back to at least 4.1.

Even explicitly importing the symbol does not help:
  use m1, only: sub
