to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
llvm-svn: 351636
Adds a new esan public interface routine __esan_get_sample_count() and uses
it to ensure that tests of sampling receive the minimum number of samples.
llvm-svn: 275948
Summary:
Adds a new public interface routine __esan_report() which can be used to
request profiling results prior to abnormal termination (e.g., for a server
process killed by its parent where the normal exit does not allow for
normal result reporting).
Implements this for the working-set tool. The cache frag tool is left
unimplemented as it requires missing iteration capabilities.
Adds a new test.

llvm-svn: 274964
Summary:
Adds a global variable to specify the tool, to support handling early
interceptors that invoke instrumented code, thus requiring shadow memory to
be initialized prior to __esan_init() being invoked.

llvm-svn: 271714
Summary:
Adds processCompilationUnitInit and processCompilationUnitExit
for compilation unit init/exit.
Adds a tool-specific argument passed to esan_init.
Adds the dtor and esan_exit called from the dtor.
A test will be added separately (adding it here results in failure until
the corresponding compilation patch is in place).

llvm-svn: 270624
Summary:
Adds the initial version of a runtime library for the new
EfficiencySanitizer ("esan") family of tools. The library includes:
+ Slowpath code via callouts from the compiler instrumentation for
each memory access.
+ Registration of atexit() to call finalization code.
+ Runtime option flags controlled by the environment variable
ESAN_OPTIONS. The common sanitizer flags are supported such as
verbosity and log_path.
+ An initial simple test.
Still TODO: common code for libc interceptors and shadow memory mapping,
and tool-specific code for shadow state updating.
