Chandler Carruth 9aaf156f30 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.

Chandler Carruth 9359efa986 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.

Kostya Serebryany 0e0832bfdb [asan] get rid of '#include <malloc.h>' in the implementation of malloc interceptors
llvm-svn: 159132
2012-06-25 09:58:29 +00:00
Chandler Carruth c78ad00c07 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.

Chandler Carruth 6e2bf8f2bb Mechanical change to sink a #ifdef guard for a platform below the
include of int_lib.h.

The purpose of this change is to make the C code conform to the pedantic
rules of C99 -- an empty translation unit is not valid. It should have
absolutely no functional impact, and changes nothing about the built
libraries.

Alexander Potapenko f9f2fbacb3 Actually intercept free() to ensure that the deallocations caused by other functions directly calling it are routed to our allocator.
For the allocations that do not belong to any malloc zone check whether they're padded with a pointer to ASan's CFAllocator. If so, free the original (unpadded) pointer.
This should fix AddressSanitizerMac.NSURLDeallocation and issue 70.

Chandler Carruth bf22bd21e9 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.

Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).
