If one changes the order of the USE statements or remove the second USE
statement, it works:
module MyMod3
USE MyMod2, only: write_MyInt => write_int
USE MyMod1, only: i2_
end module MyMod3
Looking at the MOD file,
(('write_myint' 'mymod2' 2))
is missing for the original example, but present if one one does either change
mentioned above.

is a MODIFY_EXPR. Gimple looks like
self->bounds = {};
self->coordBounds = self->bounds;
self->D.30021.dirty = 1;
gimplified from
self->coordBounds = self->bounds = NSZeroRect;
self->D.30021.dirty = 1;
I don't think this is a dup.
Gimplifying the rhs with fb_rvalue creates self->bounds = {}; w/o converting
that to tuples. It dispatches to gimplify_modify_expr_rhs which generates
it but returns GS_UNHANDLED right away, which looks bogus:
case VAR_DECL:
/* If we're assigning from a constant constructor, move the
constructor expression to the RHS of the MODIFY_EXPR. */
if (DECL_INITIAL (*from_p)
&& TYPE_READONLY (TREE_TYPE (*from_p))
&& TREE_CODE (DECL_INITIAL (*from_p)) == CONSTRUCTOR)
{
*from_p = DECL_INITIAL (*from_p);
ret = GS_OK;
}
ret = GS_UNHANDLED;
break;
So yes - it's a dup in that its caused by the same patch.
Even if you fix the above to return GS_OK, the modified initialization will
not get tuplified.

This may be a duplicate of PR34393 and/or PR34412, but it does not seem totally
target specific. The following code (extracted from the Polyhedron test suite):
SUBROUTINE RELDISP()
IMPLICIT NONE
REAL :: SRAMB, EPSEFF
SAVE
SRAMB = SQRT(EPSEFF)
END
gives when compiled with '-O -ffast-math -mrecip' on i686-apple-darwin9:

the "SAVE" or the '-mrecip' option or if I use -m32 on

--- Comment #7 from jakub at gcc dot gnu dot org 2008-01-04 15:17 ---
This is a problem during inlining.
The call actually has &optab_table argument:
...>
arg 0
... >
and two different optab RECORD_TYPEs are involved (one from each CU).
These types are types_compatible_p (0x2ea1e300, 0x2ea1ecc0), but
not are not equal. copy_body_r calls
699 *tp = fold_indirect_ref_1 (type, new);
700 if (! *tp)
701 {
702 if (TREE_CODE (new) == ADDR_EXPR)
703 *tp = TREE_OPERAND (new, 0);
here, but as the
/* *(foo *)&fooarray => fooarray[0] */
transformation is done only if the types are equal, this isn't folded into
&optab_table[0] and so inlining creates optab_table.code COMPONENT_REF, where
its first argument is not a record/union/qual union.
Either we change fold_indirect_ref_1 to do its transformations whenever
types_compatible_p (type1, type2) rather than just type1 == type2, or if that's
too expensive IMHO at least copy_body_r should do that.

[Bug fortran/34672] [4.3 Regression] .mod file misses renamed, USEd symbol
--- Comment #2 from pault at gcc dot gnu dot org 2008-01-04 16:12 --- Another way of looking as it is that the interface is not getting renamed when MyMod3 is written. This works: MODULE MyMod1 integer, parameter :: i2_ = Selected_Int_Kind(4) END Module MyMod1 module MyMod2 INTERFACE write_int module procedure write_int_local END INTERFACE contains subroutine write_int_local(value) integer, intent(in) :: value print *,value end subroutine write_int_local end module MyMod2 module MyMod3 USE MyMod2, only: write_MyInt => write_int USE MyMod1, only: i2_ end module MyMod3 module MyMod4 USE MyMod3, write_MyInt => write_int ! Use the original name end module MYMOD4 I believe, although I have not yet checked, that when I reformed the interface handling in modules I did not change the writing part. I'll bet it uses the symbol name, rather than the symtree. This would have worked previously. Paul -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34672

[Bug tree-optimization/34043] Missed optimization causing extra loads and stores when using x86_64 builtin function together with aggregate types.
--- Comment #10 from rguenth at gcc dot gnu dot org 2008-01-04 15:35

We can 'abuse' PREs inserting of fake stores machinery to handle the case in
PR33989, where for
union a
{
int i;
float f;
};
void f (float *a, int *b)
{
union a c;
c.f = *a;
*b = c.i;
}
we then get (PRE)
:
# VUSE
D.1549_2 = *a_1(D);
# SFT.0_8 = VDEF
# SFT.1_9 = VDEF
c.f = D.1549_2;
uniontmp.12_13 = VIEW_CONVERT_EXPR(D.1549_2);
D.1550_3 = uniontmp.12_13;
# SMT.7_11 = VDEF
*b_4(D) = D.1550_3;
return;
and before expand:
:
# SMT.7_11 = VDEF
*b = VIEW_CONVERT_EXPR(*a);
return;
and finally
f:
.LFB2:
movl(%rdi), %eax
movl%eax, (%rsi)
ret
but we need to make sure VN processes the inserted conversions (which do
not have uses) and we need to enhance PREs poolification of trees to
handle COMPONENT_REFs (and possibly more).

[Bug tree-optimization/34677] New: PREs insert_fake_stores is mostly useless
Because it only handles stores through direct INDIRECT_REFs. So while we
handle
testcases like loadpre4.c:
int main(int *a, int argc)
{
int b;
int c;
int i;
int d, e;
for (i = 0; i < argc; i++)
{
e = *a;
*a = 9;
}
return d + e;
}
the much simpler
int a;
int foo(int argc)
{
int b;
int c;
int i;
int d, e;
for (i = 0; i < argc; i++)
{
e = a;
a = 9;
}
return d + e;
}
or the only slightly more complex
struct {
int a;
int large[100];
} x;
int foo(int argc)
{
int b;
int c;
int i;
int d, e;
for (i = 0; i < argc; i++)
{
e = x.a;
x.a = 9;
}
return d + e;
}
is not handled. If you disable insertion of fake stores completely, only
two loadpre tests fail in tree-ssa.exp. Did the new SCCVN obsolete some
cases where we needed the fake stores before but do not so now?

--- Comment #5 from jakub at gcc dot gnu dot org 2008-01-04 17:09 ---
That's only part of the problem. The other is that ompexpand is very upset if
new basic blocks are inserted in unexpected places, e.g. on the BRANCH_EDGE
from OMP_FOR bb or on the FALLTHRU_EDGE from OMP_CONTINUE. expand_omp_for_*
changes the CFG a lot and so adding profile insns on the edges it will revamp
is premature.
The following patch lets me make -C gcc -k check
RUNTESTFLAGS='--target_board=unix/-fprofile-arcs gomp.exp'
and
make -C */libgomp -k check RUNTESTFLAGS='--target_board=unix/-fprofile-arcs'

Just not inserting the instrumentation would lead to profile mismatch
and strange errors with -fprofile-use or gcov. Why those edges are not
marked as ABNORMAL when they can not be split? That would drive
profile.c to not instrument them or if we don't want to ABNORMALize them
for some reason (perhaps we want cleanp_cfg to thread them), then checks
for them in profile.c at same time ABRNORMAL edges are handles is right
thing to do.

[Bug fortran/34665] Cannot pass scalar to array argument 'a'
--- Comment #3 from burnus at gcc dot gnu dot org 2008-01-04 19:28 --- > We catch this with an explicit interface, but we > should still check for occurrence in the > same source code. I do not understand this part. There is an explicit interface available as both are contained in the same main program. >From Fortran 2003's "12.4.1.2 Actual arguments associated with dummy data objects": "If the actual argument is scalar, the corresponding dummy argument shall be scalar unless the actual argument is of type default character, of type character with the C character kind (15.1), or is an element or substring of an element of an array that is not an assumed-shape or pointer array." I think this has to be fixed in interface.c's compare_parameter. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34665
[Bug target/19161] No emms or femms emitted between MMX and FP instructions
--- Comment #22 from Richard dot Barnes at stratus dot com 2008-01-04 20:05 --- I have seen this bug in the vector-2 testcases shipped in gcc/gcc/testsuite/gcc.dg/compat when compiling for i386 with -msse2. In vector-2_y.c and vector-2_x.c we end up using both mmx and x87 registers in the same function without any intervening EMMS instruction. This fails in 4.1.2, 3.4.6, and 3.3.1. -- Richard dot Barnes at stratus dot com changed: What|Removed |Added CC||Richard dot Barnes at ||stratus dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19161
[Bug c++/33911] attribute deprecated vs. templates
--- Comment #3 from jason at redhat dot com 2008-01-04 22:23 --- Subject: Re: attribute deprecated vs. templates niemayer at isg dot de wrote: > I can second that problem for template member functions - in contrast to > non-template member functions, where the attribute works. This is a parser bug: parsing the member template declaration winds up in cp_parser_init_declarator, which ignores attributes at the end of a declaration. A normal member function goes through cp_parser_member_declaration, which handles the attributes properly. You can work around this bug by moving the attribute into the decl-specifier-seq, i.e. "void __attribute ((deprecated)) foo(T&)". Jason -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33911
[Bug debug/19523] [4.0/4.1/4.2/4.3 Regression] DBX_USE_BINCL support broken in the C++ compiler
--- Comment #11 from tromey at gcc dot gnu dot org 2008-01-04 22:04 --- I took a look at the attached patch. I don't like it much. I think it puts the work in the wrong place -- libcpp and the lexer -- when, IMO, the problem should be addressed by changing dbxout.c (and perhaps the debug API). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19523
