Alexander Potapenko 7e07f56811 Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports. 
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.

Alexander Potapenko f519564d7c Make compiler-rt/trunk/lib/asan compileable with Visual Studio 2008 on Windows. 
Patch by Timur Iskhodzhanov (timurrrr@google.com)

To test:
$ cl /c *.c*
in the asan directory.

The code fails to link if you omit the "/c" part but that's one of the
next steps,
as well as a few TODO's I've put into the Windows-specific code.

Kostya Serebryany 809632e28e [asan] interceptors for strcasecmp and strncasecmp. patch by samsonov@google.com 
llvm-svn: 147304
 2011-12-28 02:24:50 +00:00
Kostya Serebryany 8b981c2564 The code instrumented with ASan may have its own instance of the 
mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).

The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.
The corresponding AddressSanitizer bug is
