How to use AddressSanitizer of gcc-4.8 on Arm target

AddressSanitizer of Gcc-4.8 is not available on Arm arch yet. I have found
it in gcc-4.8 release note.
But, I want to try to use asan on arm target. In my case, when I compiled a
sample with fsanitizer=address option I have faced the following warning
message. And Asan did not detect memory error. I think it does not work on
the arm target.
Is there any way to test AddressSanitizer on arm through changing compile
option or enable some-feature?

$ arm-none-linux-gnueabi-gcc -fsanitize=address -fno-omit-frame-pointer -g
-o test use-after-free.c
use-after-free.c:1:0: warning: -fsanitize=address not supported for this
target [enabled by default]
#include <stdlib.h>
^

regards,
Jungsoo

Fwd: Problem calling C .dll library from Fortran using ISO_C_BINDING

Hi everyone!
I am writing Fortran code on Windows 7 32-bit with MinGW.
I am using the Fortran 2003 feature that allows to access APIs
contained in a third party .dll library (probably) written in C with
some success as I have been able to call an initialization function
and a function that returns the library version.

The problems come when I try to call a function to create a new file
that requires three arguments: a file ID, the path to the file
including its name and the path to a folder to store the temporary
files. The documentation defines the syntax of the function as
follows:

long NewFile(long fID, char* Filename, char* Path)

In Fortran I have created an interface:

INTERFACE
FUNCTION NewFile(uID,FileName,Path) BIND(C, NAME='NewFile')
USE, INTRINSIC :: ISO_C_BINDING, ONLY: C_CHAR, C_LONG
   IMPLICIT NONE
   INTEGER(C_LONG) :: NewFile
   INTEGER(C_LONG), VALUE :: fID
   CHARACTER(C_CHAR) :: Filename(*)
   CHARACTER(C_CHAR) :: Path(*)
END FUNCTION
END INTERFACE

Then I call the function with:

Fwd: Method call and calling convention

Hello!
I have faced a problem using GDB with GCC 4.8.0 x86 on Windows XP and
Ubuntu 12.04. Here is the issue description.

GDB has commands to call function from the program being debugged.
They are print and call. But unfortunately the mentioned above
commands work incorrectly for class methods with __thiscall calling
convention. Windows x86 targets are using the __thiscall calling
convention for C++ class-member functions by default from GCC 4.7.
Judging by command return values GDB does not set object address (this
pointer) to ECX registry before method call. So these commands trigger
for some object only if last executed line of the program being
debugged contains method call for the same object. In this case ECX
registry will contain necessary address (this pointer). For methods
with __cdecl calling convention print (call) works perfectly.

Could you please tell me if this is a bug, feature or maybe I do
something wrong?

Thanks,
Petr

C++ program Test:

01: #include <iostream>
02: class Test
03: {
04:    public:
05:        Test(int value) : _value(value) {}
06:        int value() const __attribute__((thiscall)) { return _value; }

LTO : how to specify number of chunks with option -flto-partition=balanced

-flto-partition=balanced is used to specify partitioning into equally 
sized chunks.
Is there an option to specify size or number of chunks?

Good for you, but I'm behind seven proxies; I have to use http :(

SVN checkout failure

Hi all,
I'm trying to download and build GCC, but the checkout fails with:

$ svn checkout http://gcc.gnu.org/svn/gcc/trunk sources
svn: access to '/svn/gcc/!svn/ver/184997/trunk/zlib/contrib/masmx64/bld_ml64.bat'

What's going on?

Potentially bogus warning about anonymous types

Hello,

A while ago I encountered what I believed to be a bogus warning 
of the form "... uses the anonymous namespace" with GCC 4.8.

I posted http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54060 ,
and I was told there that:

 1. The warning is meant to say "... uses an anonymous type"
    rather than "... uses the anonymous namespace".
 2. Aside from the poor wording, the warning is not bogus
    because it points out a potential ODR violation.

I recently encountered the same warning in a different situation,
but I don't see where the potential ODR violation is this time.
I suspect there may not be one (and thus the warning really is
bogus in this case), but I wanted to double-check before filing
a bug.

Here is the code in question:

test.cpp:

#include "test.hpp"

test.hpp:

template <typename T>
struct base
{

gcc trunk bootstrap fails on darwin with linker assertion

I've seen this problem on and off several times now (including with the 
4.8.0 release).  Bootstrap fails linking xgcc in stage 2 with a linker 
assertion:

ld: Assertion failed: (cfiStartsArray[i] != cfiStartsArray[i-1]), 
function parse, file 
/SourceCache/ld64/ld64-136/src/ld/parsers/macho_relocatable_file.cpp, 
line 1555.

System is running MacOS X 10.8.3 with Xcode 4.6.1.  Has anybody else 
seen this error?  Unfortunately it comes and goes seemingly at random.

Thanks,

Dara
