Evgeniy Stepanov b52e3aba3f [asan] Disable preload tests on Android.
They don't test what they claim to because LD_PRELOAD applies to "not" instead
of the actual test binary. And all Android tests run with LD_PRELOAD anyway.

Jay Foad 0160570a0f [ASan] Fix leak tests on 64-bit targets other than x86-64 (take two)
Summary:
First, remove lit configuration that sets ASAN_OPTIONS to detect_leaks=1
because this is already the default when leak detection is supported.
This removes a bit of duplication between various lit.cfg files.

Second, add a new feature 'leak-detection' if we're targetting x86_64
(not i386) on Linux.

Third, change a couple of tests that need leak detection to require the
new 'leak-detection' feature.

Eric Fiselier 909deebfc8 [compiler-rt] Make the MSAN wmemset intercepter call wmemset instead of memset. Fixes PR 21579
Summary:
Exactly what the title says. I've tested this change against the libc++ test failures and it solves all of them. The check-msan rule also still passes.
I'm not sure why it called memset originally. 

I can add tests if requested but currently there are no tests involving wide chars and they are a c++11 features.

Jay Foad e47130e407 [ASan] Get fake stack code working with GCC 4.8.2.
Summary:
TestCases/Linux/heavy_uar_test.cc was failing on my
PowerPC64 box with GCC 4.8.2, because the compiler recognised
a memset-like loop and turned it into a call to memset, which
got intercepted by __asan_memset, which got upset because it was
being called on an address in high shadow memory.

Use break_optimization to stop the compiler from doing this.

Kuba Brecka 638bb4a2a3 Make the ASan OS X DYLD_INSERT_LIBRARIES detection path-independent
Reviewed at http://reviews.llvm.org/D6238

ASan on Darwin during launch reads DYLD_INSERT_LIBRARIES env. variable and if it's not set or if the ASan dylib is not present in there, it relaunches the process. The check whether the dylib is present in the variable is now trying to find a full path in there. This fails in the scenarios where we want to copy the dylib to the executable's directory or somewhere else and set the DYLD_INSERT_LIBRARIES manually, see http://reviews.llvm.org/D6018.

Let's change the search in DYLD_INSERT_LIBRARIES to only look for the filename of the dylib and not the full path.

64-bit targets, but needs to be restricted further so it only runs on
x86-64.

Jay Foad 1180c05db2 [ASan] Improved stack overflow detection for PowerPC64
Summary:
AsanOnSIGSEGV has some heuristics for detecting stack overflow, but
they don't cope with a PowerPC store-with-update instruction which
modifies sp and stores to the modified address in one instruction.

This patch adds some PowerPC-specific code to check for this case.

This fixes the last few cases of the stack-overflow test.

Jay Foad 66928be0af [ASan] Really fix zero_page_pc test for PowerPC
Summary:
As a follow-up to D6167, this patch fixes the test to account for
another difference between PowerPC and x86 systems.

On x86 if you branch to an invalid address, you get a SIGSEGV with PC
set to the invalid address (and si_addr in the siginfo struct also set
to the same address).

On PowerPC, you get a SIGSEGV with PC pointing at the branch
instruction, but si_addr set to the invalid address.

You can see this difference if you run the test case under gdb.

Jay Foad 8e586617c4 InstrProf: support PowerPC64
Summary:
I don't know anything about profiling but it seems to work out of the
box on PowerPC64. At least "make check-profile" works.

A few tests needed tweaking because PowerPC64 IR declares main with
"define signext i32 @main" instead of just "define i32 @main".

This also fixes the asan asan_and_llvm_coverage_test test, which
compiles with -coverage so requires that a profiling version of
libclang_rt has been built.
