[Bug gcov-profile/58602] .gcno files not truncated at gcov_close
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58602 --- Comment #4 from Laurent Aflonsi laurent.alfonsi at st dot com --- When the .gcno graph file is opened for generating the coverage graph information, the mode used is w+ as this code is shared with updating tools such as libgcov. Thus, when GCC outputs .gcno files, it may leave garbage at the end of the file if the file already exists when opening it. This has been trackeddown from a kernel issue on lcov: http://sourceforge.net/p/ltp/mailman/message/31141937/ This patch fixes the function gcov_open() such that the .gcno file is opened with truncation when gcc asks for creating a new file (mode0). which I also proposed on the mailing list some time ago, but i got no feedbacks. http://gcc.gnu.org/ml/gcc-patches/2013-10/msg00254.html Here is a Changelog: 2013-10-03 Laurent Alfonsi laurent.alfo...@st.com PR gcov-profile/58602 * gcc/gcov-io.c (gcov_open): Open with truncation when mode0 Regards, Laurent

Fortran 2008 (12.6.4) says that this is necessary to hide ! the host-associated declaration integer :: two two() = 7 end subroutine bar end module foo These refer to the pointer function: --- Example 1 --- two() = 7 contains function two () integer, pointer :: two allocate(two) end function two end --- Example 2 --- module foo contains function two () integer, pointer :: two allocate(two) end function two end module program use foo two() = 7 end program --- Example 3 --- module foo contains function two() integer, pointer :: two allocate(two) end function two subroutine bar() two() = 7 end subroutine bar end module foo And these are not allowed at all based on 11.2.2.8 and 16.3.1.3, because they result in a name clash: --- Example 1 --- integer :: two two() = 7 contains function two () integer, pointer :: two allocate(two) end function two end --- Example 2 --- module foo contains function two () integer, pointer :: two allocate(two) end function two end module program use foo integer :: two two() = 7 end program

[Bug c++/58875] New: No float to int conversion warning in std::inner_product(x, x_end, y, 0)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58875
Bug ID: 58875
Summary: No float to int conversion warning in
std::inner_product(x, x_end, y, 0)
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: yangzhe1990 at gmail dot com
The correct code should be std::inner_product(x, x_end, y, 0.0), but with
-Wconversion enabled, there should be a float to int conversion warning.
Without the warning it's easy to write the wrong code and get the wrong answer.
For example, compiling
#include algorithm
#include iostream
int main() {
float x[3] = {0.5, 0.5, 0.5};
std::cout std::inner_product(x, x + 3, x, 0) std::endl;
int y = 0;
y += x[1];
return 0;
}
generates the following warnings,
test.cpp: In function ‘int main()’:
test.cpp:8:4: warning: conversion to ‘float’ from ‘int’ may alter its value
[-Wconversion]
y += x[1];
^
test.cpp:8:4: warning: conversion to ‘int’ from ‘float’ may alter its value
[-Wconversion]
But a warning to the inner_product line is expected.
[Bug c++/58876] New: No non-virtual-dtor warning in std::unique_ptr
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58876
Bug ID: 58876
Summary: No non-virtual-dtor warning in std::unique_ptr
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: yangzhe1990 at gmail dot com
When compiling the following code
#include memory
struct A {
virtual void f() = 0;
};
struct B : public A {
virtual void f() {};
};
int main() {
std::unique_ptrA p(new B());
A *q = NULL;
delete q;
return 0;
};
the compiler shows the following warning,
test.cpp: In function ‘int main()’:
test.cpp:14:9: warning: deleting object of abstract class type ‘A’ which has
non-virtual destructor will cause undefined behaviour
[-Wdelete-non-virtual-dtor]
delete q;
But a warning at the unique_ptr line is also expected.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55936 --- Comment #5 from Richard Biener rguenth at gcc dot gnu.org --- Equivalences should instead of refering to SSA names (and their current value-range) refer to value-ranges (have a hashtable of value-ranges and an array we can record indexes of). Equivalences should be added exclusively by intersect_ranges when that doesn't produce a precise result. Alternatively as a hack to preserve the assert range we could add an SSA name temporarily to hold it and equivalence to that.

Related to PR 50481. The prototype for the reverse bit string builtin was designed to be useful to reverse bits in a subset of a integer value, starting at index with count bits. The general use case is likely to reverse all bits in a variable, (uint64_t for example): uint64_t v; __builtin_brev64(v, 0, sizeof(v) * 8); But I thought it might be interesting to have a more general purpose builtin. Actually, the builtin arguments for reverse should probably match what's currently available on modern hardware.

[Bug c++/58878] New: Template parameter name can be hidden in a template member function defined inside the class specifier
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58878
Bug ID: 58878
Summary: Template parameter name can be hidden in a template
member function defined inside the class specifier
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roger.ferrer at bsc dot es
Hi,
g++ allows declarations to hide a template-parameter name in template member
functions defined inside the class-specifier.
I have not been able to find whether this was expected behaviour in g++ so
I'm inclined to believe this is an error in g++.
Following is a testcase where several declarations attempt to hide
template-parameter names 't' and 's' in the scope.
g++ accepts cases 1, 5 and 6 and (I think) it should not allow them. The
remaining cases seem to be correctly diagnosed.
This fails both in g++ 4.8.1 and g++ 4.9.0 20131015 (experimental).
-- test.c

{
int t = 2; // OK. g++ DOES complain
}
// (Non-template) Members of template class

[Bug target/58879] New: PPC: Missed opportunity to use lwbrx
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58879
Bug ID: 58879
Summary: PPC: Missed opportunity to use lwbrx
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marcus at mc dot pp.se
Hi.
Please consider the following function, compiled on PPC (32 bit):
uint32_t swap32(uint32_t *in)
{
#if 1
uint8_t a[] = {
((*in) (uint32_t)0xff00UL)24,
((*in) (uint32_t)0x00ffUL)16,
((*in) (uint32_t)0xff00UL)8,
(*in) (uint32_t)0x00ffUL,
};
#else
const uint8_t *a = (uint8_t *)in;
#endif
uint32_t r =
(a[0]) |
(a[1] 8) |
(a[2] 16) |
(a[3] 24);
return r;
}
With the code in the #if branch, this results in a single lwbrx instruction.
However, with the code in the #else branch it does not (getting lbz + slwi + or
instead).
Why the uint8_t pointer? Well, my real code is a C++ template containing the
following:
uint8_t data[nBytes];
T getValue() const {
T v = 0;
int i;
for (i=0; inBytes; i++)
v |= data[i](i*8);
return v;
}
If nBytes happens to be 4 in a particular instantiation of the template, then
this collapses beatifully into a single movl instuction on AMD64. So I think
I'm not being totally unreasonable in hoping for a lwbrx on PPC (or lwz, if
-mlittle is in effect), provided strict alignment is not required of course.
I don't know how difficult it would be to make this work, but given that byte
array reassembly - word load already works on AMD64, and reverse order
reassembly already can give a lwbrx at least _sometimes_ on PPC, it seems like
it would be feasable at least. And it would be a neat trick to get efficient
code from portable source, without a lot of #ifdefs and __builtin_whatevers.
:-)
Thanks for listening

Modified testsuite/gcc.dg/cpp/line4.c to test __LINE__ use. I think I saw a stronger set of tests while 'googling' the problem. I was a bit short on understanding when I saw it, so I didn't mark it for study... I've looked at the code that handles this. It's in the libcpp tree. Thw indentation is messed up. '\t' used in many places WITHOUT consistant tab widths. I see spots with '\t' stops at 4 and at 8. Indent width is mostly 2. Style is a bit mixed. FOR MY OWN USE, I've cleaned this up. The result is much more readable. I tried a simple look-ahead hack, but no go. Going the mild KLUGE route: Use a special value to indicate the bad value and emit it under special circumstances. - define the special value CUR__LINE__ in include/libcpp.h (-1) - modify state.in_directive to have a special value (2) when in the #line directive (in do_line). - check for the CUR__LINE__ value at the end of do_line after flushing the tokens and use replace the special value with the current line number before doing the state change. - in macro.c, __LINE__ processing, look for the special stat.in_directive value and return CUR__LINE__ if it has the special value. Potential problem if someone uses __LINE__ to construct the file name. Intrest?

[Bug fortran/57957] [F03] Double free with allocatable components
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57957 --- Comment #3 from Tao Song songtao.thu at gmail dot com --- (In reply to janus from comment #2) (In reply to Tobias Burnus from comment #1) For GCC 4.9, one needs to wrap the code in the main program in BLOCK/END BLOCK as otherwise the end-of-scope deallocation does not trigger, which causes the failure. Updated test case: program main implicit none type :: type1 real, allocatable :: anum(:) end type type :: type2 type(type1) :: temp end type block type(type1) :: t1 type(type2) :: t2 t1 = type1([0.,1.]) t2 = type2(t1) end block end Note: The double free goes away when changing the line t2 = type2(t1) to t2%temp = t1 That means the actual problem is not the auto-dealloc itself (which is done properly), but the construction of t2: With the second variant, a deep copy is done (allocating a separate chunk of memory for t2%temp), while in the first one t2%temp only gets a reference to the memory allocated for t1 (which is of course wrong). Since both t1 and t2 are auto-deallocated, we try to free that memory twice. Do you mean in fortran the default structure constructor would yield a shadow copying? Is this in the standard? Thank you.
