Modified the subject to reflect the stack produced by the given example. In our

larger code base the stack was somewhat different but related. I have been

unable to produce this stack in a reduced example because of the sensitivity to

removing unused lines of code:

Correct.  Dumping order is affected by the patch though, thus if

we previously disabled vectorization at some point the dumping

before that can be affected due to the re-ordering.

At least the reduced testcase contains undefined signed integer overflow.

It multiplies 65531 by 65536 here:



  x3 = x2 * 65536;



it's still "miscompiled" with -fno-strict-overflow though, a QOI issue

(it works correctly with -fwrapv).  The docs trying to point out the

difference between -fno-strict-overflow and -fwrapv are especially poor

(ISTR strongly objecting the notion of -f[no-]strict-overflow ...)

BTW, running gkeytool without any args shows the problem too. When libjava is

built with -g -O2, I get



Exception in thread "main" java.lang.NoClassDefFoundError:

gnu.classpath.tools.keytool.Main

   at java.lang.Class.initializeClass(natClass.cc)

   at java.lang.ClassLoader.loadClass(ClassLoader.java:387)

   at java.lang.Class.initializeClass(natClass.cc:728)



But note that natObject.cc:1437 is a lie!  The real failure occurs

natObject.cc:1431 and it looks like the two identical throws have merged. 

Putting a break on the right place, I see



(gdb) p this

$8 = (java::lang::Object * const) 0xffc6aec



(gdb) p/x addr

$9 = 0xffc6aec



Uh oh!  The address is not 8-byte aligned, so one of the flag bits appears to

be set.  This is why we appear to have locking problems.

gcc49-pr57130.patch



Untested fix, though not sure if it won't pessimize too much.  The in_code ==

COMPARE handling simply look safe to me when recursing into a SUBREG. 

Sometimes it could, e.g. for (subreg:SI (and:DI (reg:DI) (const_int

0x0800))) with in_code == COMPARE, but we'd probably have to pass the

SUBREG mode around and special case it everywhere.

Another thing, it is weird we don't simplify that subreg much earlier, we know

that nonzero_bits on the inner operand has all zeros in the mode that it is

truncated to, therefore it must be zero.

I believe this is triggered by powerpc turning on -fsection-anchors by default,

and a section anchor bug loses the alignment.  The classes are all nicely

aligned if I compile with -fno-section-anchors

[Bug libgcj/57074] gcc-4.8.0 libgcj regression on 32bit Power architecture

[amodra at gmail dot com]

--- Comment #5 from Alan Modra  2013-05-02 14:01:59

So the section anchor code places vars (and constants) in blocks according to

their alignment and sizes (varasm.c:place_block_symbol).  The calculations are

all good, offsets are properly aligned, and the overall block aligned.  The

problem is that when we come to actually output the vars, in some cases we emit

*more* data than given by the size.  That results in following vars being at a

different offset than originally calculated, and sometimes misaligned.



Here's an example of output showing the mismatch.

.type   _atable_syms_gnu_classpath_tools_keytool_Main$ShutdownHook,

@object

.size   _atable_syms_gnu_classpath_tools_keytool_Main$ShutdownHook, 24

_atable_syms_gnu_classpath_tools_keytool_Main$ShutdownHook:

.long   _Utf259

.long   _Utf111

.long   _Utf110

.long   _Utf166

.long   _Utf111

.long   _Utf257

.long   0

.long   0

.long   0

Notice the actual size is 36 bytes, not the 24 give by .size.

I'm not sure how we came to think the array had 3 elements rather than 2.

 Bug #: 57144

   Summary: [4.9 regression] mpfr miscompiled after r198413

Classification: Unclassified

   Product: gcc

   Version: 4.9.0

Status: UNCONFIRMED

  Keywords: build

  Severity: normal

 Component: tree-optimization

AssignedTo: unassig...@gcc.gnu.org

ReportedBy: sch...@linux-m68k.org

Depends on: 57124

Target: ia64-*-*





r198413 is causing miscompilation of mpfr-2.4.2 on ia64, seen by a lot of

failures in its testsuite, some are looping infinitely.  This makes it

impossible to bootstrap with an in-tree mpfr, because the fortran compiler

hangs while calling mpfr_log10 from gfc_arith_init_1.



The patch in  does

not help.

I don't see how this would be related to PR28865, that PR is about .size

directive, if TYPE_SIZE is smaller than DECL_SIZE.  But from what Alan posted

here, that is not the case here, here TYPE_SIZE is the same as DECL_SIZE, 24

bytes both, and the problem is that the CONSTRUCTOR in DECL_INITIAL has 3

entries rather than two.  Perhaps gcj FE bug?

It appears that we are vectorizing the same loops, but we are now vectorizing

one loop differently.  In r196871, the loop is peeled for alignment.  In

r196872, the loop is versioned for alignment.  



I will attach the vectorization detail dumps for the two revisions.

--- Comment #2 from Martin Jambor  2013-05-02

OK, after I verified and re-verified that the call target determined

by devirtualization is actually correct, I have noticed that the call

graph of the target is an inlined node.  I'm not sure what effects

exactly that has but the following (untested) patch helps while still

performing the devirtualization (and the assembly around the calls is

slightly different).



I think that the final patch will look a bit different because a) the

new code is basically copied from ipa_make_edge_direct_to_target an

thus we'd better commonize it somehow (and I'd like to discuss with

Honza at least the name of the new function) and b) I see no reason

why the constructor-based devirtualization method in PRE cannot have

the same problem and so we'll probably want to handle it there instead

(Honza said on IRC something about a patch he already had but I am not

sure what he meant).



Another interesting point is that at least in the 64 bit non-LTO

build, these polymorphic calls are devirtualized during inlining.  I'm

going to look at why we do not do it in 32 bit LTO one (so far I do

not know which one is the problem).

This has been fixed between revisions 189610 (2012-07-18) which gives the error

and 189780 (2012-07-23). This may have been fixed by revision 189669 and/or

189678.



The test compiles with the latest 4.8.0 release, so you may consider to

upgrade.

Well, I still can't find the magic to reproduce this myself, but our overnight

tester shows the failure

(http://gcc.gnu.org/ml/gcc-testresults/2013-05/msg00094.html).



Richi, this is another test that started failing with the same commit as

PR56865.  In this case, it appears we are now vectorizing a loop that we

formerly expected not to.  Are you able to reproduce this?



Andreas, would you be able to provide -fdump-tree-vect-details information for

r196871 and r196872 to make it easier to debug the problem?



Thanks,

Bill

It looks like more overflow issues, though slightly different than 57124.  In

the case I looked at in the mpfr code we overflow converting a constant to the

desired type.  It's all downhill from there.

This is with trunk@198549.  It's a regression from gcc-4_8-branch@198420.



Preprocessed source attached.



Configured as: --target=arm-linux-gnueabi --with-arch=armv7-a

Command line below.



This example is not expected to be usable on an arm-linux-gnueabi system,

but the problem is easily seen by examining the assembly.  In the function

TestSyscall, a good compilation calls _setjmp, returns normally on a

nonzero result, and ends in an __assert_fail call (a noreturn function, so

no epilogue/return after the call) on a zero result.  In a bad compilation,

the function just ends where the _setjmp call should be, no epilogue, no

return (so execution just runs into the following function).

So, the decl in question seems to be created by:

and the DECL_INITIAL for it filled by:



#0  emit_symbol_table (name=0xf42cd7a8, the_table=0xf42cf5c0,

decl_table=0xf42cd938, the_syms_decl=the_syms_decl@entry=0xf42cf61c,

One bug seems to be

one_elt_array_domain_type = build_index_type (integer_one_node);

That name seems to be inconsistent with what it does, build_index_type

(integer_one_node); returns an index type with  , i.e. two

element array.  One element array is build_index_type (integer_zero_node);.



And, either the individual decls need to be created with different types,

depending on how many elements they will have, or at least treated as C []

arrays and at least DECL_SIZE and DECL_SIZE_UNIT need to be updated when

setting DECL_INITIAL.



>From quick skimming, emit_{symbol,assertion}_table are the only callers in

gcc/java/ of build_constructor that don't bother with sizing the array type

appropriately.

The problem is that's not the right fix.  See this thread:

Basically something needs to avoid building the C++ runtime for the 16 

bit models of the H8.  I don't think we have any configury magic for that.

You are wrong in saying the range is -2147483648 to +2147483647.  In fortran

the range is symmetrical around 0.

In the glibc file e_scalbl.c, the compiler is using VSX stxvd2x and lxvd2x

instructions to spill long double, even though only 1/2 of the register is

used.  The compiler should use scalar load/store instructions.

Not quite right.  The model numbers imply a symmetric range.

It is processor dependent on whether the most negative

value is -2147483648.  Without see the source, it's difficult

to say what OP hit. If her/his code is equivalent to



program foo

  integer i

  read(*,*) i

  print *, i

end program foo



update to 4.8. or trunk.  



This is trunk.

% gfc4x -o foo foo.f90

% ./foo

-2147483648 

 -2147483648



This is 4.7.something_revision.

gfc47 -o foo foo.f90

troutmask:sgk[214] ./foo

-2147483648 

At line 3 of file foo.f90 (unit = 5, file = 'stdin')

Fortran runtime error: Integer overflow while reading item 1



If OP tries a simple assignment he/she will hit an issue

with a unary minus operator.

Suggested patch



The problem appears in version 4.8 and in revision 198496. I attached

a one-line patch that fixes it.



In method "verify_cgraph_node" in cgraph.c, the second loop over

"node->indirect_calls" should break immediately after "error_found" is

set to "true".  All the iterations after "error_found" is set to

"true" do not perform any useful work, at best they just set

"error_found" again to "true".



Method "ix86_legitimate_combined_insn" in i386.c has a similar loop

over "recog_data.n_alternatives", and this loop breaks immediately

after "win" is set to "true", just like in the proposed patch.  Other

methods (e.g., "tagged_types_tu_compatible_p" in c-typeck.c,

"rest_of_record_type_compilation" in utils.c, "distance_agu_use" in

i386.c) also have similar loops that break like in the proposed patch.

Should I keep the bug open so it might be fixed in the 4.7 series?

[Bug middle-end/57073] __builtin_powif (-1.0, k) should be optimized to "1.0 - 2.0 * (K%2)"

[burnus at gcc dot gnu.org]

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57073



--- Comment #7 from Tobias Burnus  2013-05-02 
21:08:36 UTC ---

The problem is the following in gimplify.c:



In gimplify_cond_expr, one has:



  /* If this COND_EXPR has a value, copy the values into a temporary within

 the arms.  */

  if (!VOID_TYPE_P (type))

  ...  

  /* If either an rvalue is ok or we do not require an lvalue, create the

 temporary.  But we cannot do that if the type is addressable.  */

  if (((fallback & fb_rvalue) || !(fallback & fb_lvalue))

  && !TREE_ADDRESSABLE (type))

  ...

  tmp = create_tmp_var (type, "iftmp");

  result = tmp;



This is then used in the then_ and else_ branches, e.g.



 

arg 1 

constant 1.0e+0>>



That's passed to gimplify_modify_expr, where one runs into the assert:



  if (gimplify_ctxp->into_ssa && is_gimple_reg (*to_p))

{

  /* We should have got an SSA name from the start.  */

  gcc_assert (TREE_CODE (*to_p) == SSA_NAME);

}



which fails as the TREE_CODE of "iftmp.1" is VAR_DECL.

--- Comment #8 from Tobias Burnus  2013-05-02 
22:00:53 UTC ---

For completeness, gimplify_ctxp->into_ssa is 0 for the -O0 optimization and it

gets set to 1 in gimple_regimplify_operands. Thus, it is not surprising that it

works with the -O0 example ("(-1.0)**k") but not with the -O1 example

("a=-1;a**k").



If one ignores the assert, one runs into: control flow within basic block 2.

Another fairly easy fix is to make output_object_block() emit the .align

directives instead of padding.  Yes, this covers up the real bug that Jakub has

been looking at, but it might be worth doing for robustness.

Test case



The included test case produces the following error:



% g++-4.7 -std=c++11 test.cpp 

test.cpp: In constructor 'constexpr B<0>::B()':

test.cpp:8:8: error: use of deleted function 'A::A(const A&)'

test.cpp: In function 'int main()':

test.cpp:17:9: note: synthesized method 'constexpr B<0>::B()' first required

I don't think a copy constructor of the member should be needed for the default

constructor of the containing struct.



The error disappears when I declare the latter explicitly, but not when I

declare it as "= default".



Is also disappears if struct B is not a template. I don't see why this should

make a difference.
