Significantly change the way we build ASan unittests in CMake
...
build tree. Now just-built Clang is used to:
1) compile instrumented sources (as before);
2) compile non-instrumented sources;
3) compile our own instrumented version of googletest;
4) link it all together using -fsanitize=address flag
(instead of trying to copy linker behavior in
CMake build rules).
This makes ASan unittests pretty much self-consistent
and independent of other LLVM libraries.

it fixed.

Relocate the external headers provided by ASan and the common sanitizer
...
library.
These headers are intended to be available to user code when built with
AddressSanitizer (or one of the other sanitizer's in the future) to
interface with the runtime library. As such, they form stable external
C interfaces, and the headers shouldn't be located within the
implementation.
I've pulled them out into what seem like fairly obvious locations and
names, but I'm wide open to further bikeshedding of these names and
locations.
I've updated the code and the build system to cope with the new
locations, both CMake and Makefile. Please let me know if this breaks
anyone's build.
The eventual goal is to install these headers along side the Clang
builtin headers when we build the ASan runtime and install it. My
current thinking is to locate them at:
<prefix>/lib/clang/X.Y/include/sanitizer/common_interface_defs.h
<prefix>/lib/clang/X.Y/include/sanitizer/asan_interface.h
<prefix>/lib/clang/X.Y/include/sanitizer/...
But maybe others have different suggestions?
Fixing the style of the #include between these headers at least unblocks
experimentation with installing them as they now should work when
installed in these locations.

Some flag cleanup for the sanitizer runtimes.

This hoists most of the CFLAGS into a common variable. It also adds

warnings.
Finally, it switches to the proper flag -rdynamic.
With this, the cmake build is warning free on my bootstrap Linux build.

[ASan] Create new files asan_report.{h,cc} as a preparation for refactoring of ASan error reporting code.
...
Currently ASan reports many kinds of errors, and the code that actually prints error messages can
be found inside allocator, OS-specific files, interceptors code etc.
An example of maintenance troubles this situation causes:
There is currently an ASan interface function that registers
callback which should take the char buffer with error report printed by ASan.
This function is now broken, as one has to insert callback calls to all the places in
ASan code where the error reports are printed, surprisingly it is not only
"__asan_report_error" function...

First tiny move towards integrating AddressSanitizer regressions test into LLVM lit-based testing infrastructure.
...
The goal is to be able to run ASan tests by simply running "make check-asan" command from CMake build tree:
* tests should use fresh clang binary from current build tree.
* tests should use the same RUN-lines syntax as llvm/clang reg tests.
Next steps:
- restricting tests to machines where target is equal to host, i.e. where we can produce working binaries.
- moving AddressSanitizer unit tests to lit as well.

Add support for building the ASan instrumentation unit tests with the
...
just-built Clang binary, and linking them against the just-built ASan
runtime.
This is *very* brittle. I expect it will require tweaking, and I've
pro-actively disabled it on non-Unix builds and on cross-builds.
It is also currently missing dependency edges on GoogleTest header files
and a few other corner cases, but those can be fixed. This is the major
milestone of a mini-bootstrap-like build of the unittest.

Cleanup the handling of CFLAGS even more in the cmake build for ASan.
...
Add the initial support for building ASan tests.
The first change here is to try to get the CFLAGS to more closely match
those used by the old Makefile. There are probably still goofs here,
ASan folks, your review would be appreciated.
The second big change is to add support for building both
instrumentation based an non-instrumentation based unittests for ASan.
They are built a bit differently from how the old makefiles managed
things. Specifically, there are two binaries, one for the
non-instrumented case, and one for the instrumented case.
Also, the instrumented unit tests rely on the host compiler supporting
AddressSanitizer's intrumentation pass. This is kind-of gross, but
I don't know of a better way yet. I've mailed llvmdev to discuss this
issue.
One big caveat is that the detection logic currently doesn't work. I've
commented it out temporarily as I'd like to get feedback from the ASan
developers, etc.

Another big step toward a viable CMake build system for CompilerRT,
...
ASan, and friends.
This explicitly switches the CompilerRT CMake build to require CMake
version 2.8.8 or newer which provides first-class support for "object"
libraries which consist of a pile of '.o' files -- exactly what is
desired for composing runtime libraries. I've gone ahead and switched to
using this.
I've also added the interception library which I missed initially. And
I've added proper dependencies between the various libraries. With this,
I'm able to build archives for asan that appear to contain all of the
necessary .o files.
The final tweak here is to start setting up the compile flags and macro
defines expected by ASan and its helper libraries. These may not be
entirely correct currently, they're based loosely on my reading of the
old Makefiles. However, they can be tweaked more easily now that they're
wired up properly.

Resuming work on the compiler-rt CMake build at long long last. In order
...
to get it working again, two changes were needed:
- I had to give up on glob-based file expansion. This just isn't well
supported by CMake, and until we convince upstream there of its value,
it's not worth dealing with the pain.
- Add the common library as otherwise even ASan won't build.
This now builds again, although the "correctness" of it is a touch
debatable. ;] Specifically, there is no merging of the common runtime
library with the asan runtime library into a single archive file. I'm
not really sure what the best technique is for that, and it may be
influenced by the ongoing discussion about how best to link runtime
libraries.
Note of course that this is still very much WIP. It doesn't entirely
work yet, and remains disabled by the LLVM projects/CMakeLists.txt until
it is in a working state.
