[Bug lto/54095] Unnecessary static variable renaming
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54095 --- Comment #6 from Jan Hubicka hubicka at ucw dot cz 2012-09-19 08:23:45 UTC --- --- Comment #5 from Richard Guenther rguenth at gcc dot gnu.org 2012-09-18 14:20:45 UTC --- Created attachment 28215 -- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28215 patch More complete patch, still has issues. We rely on the name mapping to find LTO data but that for some reason is confused when we try to rename late. Which you can see from LTO testsuite fails caused by this patch. At least with the partitioning reorg the patch doesn't look as bad as before ;) Hehe, the partioning reorg was intended to give us some room to insert new uglyness into the area ;) I suppose that is because you rename late and the renaming code do not work with presence of inline clones. I will debug that. Thanks, Honza

Since deserialize is an implicit instantiation, the compiler only emits it in places where it is needed, and it isn't needed in this translation unit because all uses have been inlined. G++ expects that the definition of a template will be available in all translation units that use it unless it is explicitly instantiated. You can use -O2 -fno-inline-small-functions to restore the older behavior.

[Bug target/54626] New: Unexpected consequences of __attribute__((optimize(-fno-PIC)))
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54626
Bug #: 54626
Summary: Unexpected consequences of
__attribute__((optimize(-fno-PIC)))
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: jep...@unpythonic.net
(I doubt I've selected the right component; please correct)
I ran across bug 54232 and it occurred to me to wonder whether it was possible
to manually mark a single function that uses no global data (and thus does not
need to use ebx as the GOT register) as no PIC.
This has the unexpected side-effect of making the entire translation unit no
PIC.
Source code:
extern int o();
int f() __attribute__((optimize(-fno-PIC)));
int f() { return o(); }
g() { return o(); }
Compiler commandline:
gcc -m32 -fPIC -c ff.c
Expected behavior: when examined with 'objdump -d ff.o', function f contains no
call to get_pc_thunk.bx while g does. Alternately, the __attribute__
declaration results in an error if this is totally nonsensical.
Actual behavior: both f and g are compiled without call to get_pc_thunk.bx
Tested on svn trunk r19144:
Using built-in specs.

[Bug fortran/54618] [OOP] wrong-code with CLASS(...), INTENT(OUT) -- and OPTIONAL or ALLOCATABLE
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54618
--- Comment #2 from Tobias Burnus burnus at gcc dot gnu.org 2012-09-19
13:31:19 UTC ---
Draft patch for the second issue. Note the FIXME for resetting to the declared
type.
Additionally, the patch fixes only the scalar issue, the same has also to be
done for arrays.

So the only used equivalence bitmaps are for operands of those. equivalences are generated only by asserts and SSA name copies, so they can be computed up-front and shouldn't change (apart from handling of non-executable edges in PHI nodes) during iteration. At least equivalence processing can be ignored for SSA name chains not leading up to a condition operand.

[Bug fortran/54618] [OOP] wrong-code with CLASS(...), INTENT(OUT) -- and OPTIONAL or ALLOCATABLE
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54618
--- Comment #3 from Tobias Burnus burnus at gcc dot gnu.org 2012-09-19
17:31:06 UTC ---
There seem to be other issues with OPTIONAL as well. The following code prints
twice 'T' when it should print 'F' and it segfaults for one version.
I haven't dared to combine it with INTENT(OUT) and/or ALLOCATABLE.
The following program gives the same result with 4.7 as with 4.8 + my patch:
type t
end type t
type(t) :: y, y2(2)
class(t), allocatable :: z, z2(:)
allocate (t :: z)
allocate (t :: z2(2))
!print *, 'Scalars, expected: F F T T T T'
call s1() ! OK
call s1a() ! - should print 'F', prints 'T'
call s1(y) ! OK
call s1a(y) ! OK
call s1(z) ! OK
call s1a(z) ! OK
!print *, 'Arrays, expected: F F T T T T'
! call sa1() ! Segfault
call sa1a() ! - should print 'F', prints 'T'
call sa1(y2) ! OK
call sa1a(y2) ! OK
call sa1(z2) ! OK
call sa1a(z2) ! OK
contains
subroutine s1(x)
class(t), optional :: x
call s2(x)
end subroutine s1
subroutine s1a(x)
type(t), optional :: x
call s2(x)
end subroutine s1a
subroutine s2(x)
class(t), optional :: x
print *, present(x)
end subroutine s2
subroutine sa1(x)
class(t), optional :: x(:)
call sa2(x)
end subroutine sa1
subroutine sa1a(x)
type(t), optional :: x(:)
call sa2(x)
end subroutine sa1a
subroutine sa2(x)
class(t), optional :: x(:)
print *, present(x)
end subroutine sa2
end
* * *
The missing bits for the patch in comment 2 are fixable as follows, which
completes the scalar version of the second issue.

19:44:14 UTC ---
Richi, Diego. Perhaps you can shed light on this.
Here we have a loop unroll that triggers a virtual def operand missing... for
a GIMPLE_TRANSACTION:
int vec[500];
void func()
{
__transaction_relaxed
{
vec[123] = 456;
}
}
main()
{
int i;
for(i = 0; i 10; ++i)
func();
}
The unroller wants to unroll into something like:
bb 2:
# .MEM_6 = VDEF .MEM_13
__transaction_relaxed-- PROBLEMATIC INSN (VDEF's)
bb 3:
# .MEM_9 = VDEF .MEM_59
vec[123] = 456;
# .MEM_2 = VDEF .MEM_9
__builtin__ITM_commitTransaction ();
bb 4:
ivtmp_14 = 9;
# .MEM_11 = VDEF .MEM_13
__transaction_relaxed
bb 5:
# .MEM_18 = VDEF .MEM_59
vec[123] = 456;
# .MEM_19 = VDEF .MEM_18
__builtin__ITM_commitTransaction ();
etc etc etc.
Putting aside how incredibly inefficient this is... (We should be duplicating
the vector store, not the entire transaction)...
The problem here is that, after unrolling, the VDEF of the problematic insn is
.MEM_6, but the DEF_OP of the insn is .MEM_59. So gimple_vdef() !=
gimple_vdef_op() and we trigger a virtual def operand missing for stmt.
The problem is that the unroller's call to gimple_duplicate_bb() will make a
copy of the problematic instruction, maintaining its gimple_vdef, but changing
all its def_ops from under us, thus making gimple_vdef() != gimple_vdef_op().
Before loop unrolling we have this snippet that is about to be unrolled:
bb 3:
# .MEM_13 = PHI .MEM_8(6), .MEM_3(D)(2)
# ivtmp_1 = PHI ivtmp_10(6), 10(2)
# .MEM_6 = VDEF .MEM_13
__transaction_relaxed
After loop unrolling the above remains unchanged, but the following is inserted
*before* bb 3. [Note, the following is after update_ssa(TODO_update_ssa), but
before cleanup_tree_cfg() for clarity.]
bb 8:
# .MEM_12 = PHI .MEM_3(D)(2)
# ivtmp_5 = PHI 10(2)
# .MEM_6 = VDEF .MEM_13 -- *** --
-- shouldn't this be .MEM_12 ?
-- *** --
__transaction_relaxed
...
...more unrolling
...
bb 40:
# .MEM_57 = PHI .MEM_8(39)
# ivtmp_58 = PHI ivtmp_10(39)
# .MEM_53 = VDEF .MEM_13-- ** --
-- shouldn't this be .MEM_57
-- ** --
__transaction_relaxed
...
...
bb 3
..
Notice that both BB8 and BB40 invalidate MEM_13 in its virtual definition.
Shouldn't the VDEF.MEM_13 be rewritten as I have indicated above? Especially
since now .MEM_13 is defined much further down in bb 3:
bb 8
# invalidates VDEF.MEM_13
...
bb 40
# invalidates VDEF.MEM_13
..
bb 3
# define .MEM_13 =
It seems gimple_duplicate_bb() renames all the phis and the operands, but does
not update the VDEF's for the transaction. Gimple_duplicate_bb() says it
doesn't maintain SSA form, so I assume this in on purpose (?). So how is this
supposed to be cleaned up? Or is this even the problem?

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40836 --- Comment #32 from Daniel Drake dsd at laptop dot org 2012-09-19 21:02:55 UTC --- Using the preprocessed source that I attached, I can't reproduce this with gcc-4.8 head (my previous test was with 4.7.x). Also, I have completed a glibc compile with -march=iwmmxt2 on gcc-4.8. So I think this bug may have been solved post-gcc-4.7.

[Bug testsuite/54622] gcc.dg/vect test failures for arm big-endian
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54622 --- Comment #4 from Richard Earnshaw rearnsha at gcc dot gnu.org 2012-09-19 22:26:49 UTC --- The reasons for the vector problems in big-endian largely fall into two areas: 1) Neon vector elements are numbered from the LSB of the vector register in both big and little-endian modes. GCC assumes that vector elements in big-endian are numbered from the MSB. This means compensation code is needed when elements are addressed directly (for example shuffle operations). 2) Quad-words in 256-bit vectors are not pure big-endian, the DWords are swapped in order on loads. GCC can't currently cope with this in any sensible manner.

[Bug target/54631] New: vxworks.c fails to compile
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54631 Bug #: 54631 Summary: vxworks.c fails to compile Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassig...@gcc.gnu.org ReportedBy: r...@verizon.net I just pulled in the latest changes, and vxworks.c no longer compiles. The error is at bottom. I think this has to do with the upgrade to C++. The code in question does this: elt = VEC_quick_push(constructor_elt, v, NULL); The problem with this is that NULL is not convertible to const constructor_elt . I think that with the old C API this would just construct a new object, but that doesn't work anymore. Changing the code to construct the object first and then add it to the vector should work, but I don't know enough about the code to be sure. As a question, should these files be changed to use the C++ API? Or should they stick with pretending that they're straight C? Thanks!
