/* This file defines dynamic annotations for use with dynamic analysis
|
|
tool such as valgrind, PIN, etc.
|
|
|
|
Dynamic annotation is a source code annotation that affects
|
|
the generated code (that is, the annotation is not a comment).
|
|
Each such annotation is attached to a particular
|
|
instruction and/or to a particular object (address) in the program.
|
|
|
|
The annotations that should be used by users are macros in all upper-case
|
|
(e.g., ANNOTATE_NEW_MEMORY).
|
|
|
|
Actual implementation of these macros may differ depending on the
|
|
dynamic analysis tool being used.
|
|
|
|
See http://code.google.com/p/data-race-test/ for more information.
|
|
|
|
This file supports the following dynamic analysis tools:
|
|
- None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
|
|
Macros are defined empty.
|
|
- ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
|
|
Macros are defined as calls to non-inlinable empty functions
|
|
that are intercepted by Valgrind. */

/* Return non-zero value if running under valgrind.
|
|
|
|
If "valgrind.h" is included into dynamic_annotations.c,
|
|
the regular valgrind mechanism will be used.
|
|
See http://valgrind.org/docs/manual/manual-core-adv.html about
|
|
RUNNING_ON_VALGRIND and other valgrind "client requests".
|
|
The file "valgrind.h" may be obtained by doing
|
|
svn co svn://svn.valgrind.org/valgrind/trunk/include
|
|
|
|
If for some reason you can't use "valgrind.h" or want to fake valgrind,
|
|
there are two ways to make this function return non-zero:
|
|
- Use environment variable: export RUNNING_ON_VALGRIND=1
|
|
- Make your tool intercept the function RunningOnValgrind() and
|
|
change its return value.
