Greg Fitzgerald fb1d83a978 Add %run to new lit test 
llvm-svn: 208624
 2014-05-12 20:17:14 +00:00
Kostya Serebryany 118d469660 [asan] one more attempt to enable lsan by default (PR19521)

Kostya Serebryany d7992fc921 [asan] fix a self deadlock when printing stats; add a relevant test, cleanup that test while at it to remove linux/darwin differences. Fixes http://code.google.com/p/address-sanitizer/issues/detail?id=306

Duncan P. N. Exon Smith b6bd2f6cf7 InstrProf: Pacify buildbots after r208460 
llvm-svn: 208462
 2014-05-09 23:47:49 +00:00
Duncan P. N. Exon Smith 238137294f InstrProf: Test the functions in the runtime 
Check that the profile runtime works as expected.  This tests the
functions that are meant to be available to advanced users.

In particular, check that the `atexit()` hook can be disabled by
defining a custom `__llvm_profile_runtime` variable, that the libc
dependencies are optional, and that the various functions for writing
out files work for basic cases.

llvm-svn: 208356
 2014-05-08 20:21:11 +00:00
Sergey Matveev 76e02e90c5 [ASan] Fix coverage behavior when a PC belongs to an unknown address range. 
This happens, e.g., when coverage data is collected for a module which is then
dlclose()'d. Currently this causes CovDump() to ignore all PCs that are greater
than the unrecognized PC. In other words, unloading a module causes ASan to
silently ignore any coverage data for modules loaded at higher addresses.
Instead we should just skip the unrecognized PCs.

Evgeniy Stepanov 9c20cb1a7c [msan] Fix potential infinite recursion in a test. 
If printf is intercepted (it is not atm), REAL(printf) call in the interceptor
would get redirected back to my_lgamma, resulting in infinite recursion.

Kostya Serebryany 4f9c31a2fa [asan] split detect_odr_violation into two: =2 detects all ODR violations, =1 detects only those where the variable sizes are different. BTW, the detector seems to be working well and finding nice bugs. Early adopters are welcome.

 2014-02-19 11:02:46 +00:00
Alexey Samsonov aa980c760b [CMake] Add the way to run tests in standalone build. 
1) Depend on llvm-config (configured in LLVM_CONFIG_PATH) to
get necessary LLVM source/binary directories.
2) Add basic support for running lit tests (check-xsan commands).
For now this "support" is far from what we want:
  * unit tests are not built currently.
  * lit tests use Clang/compiler-rt from LLVM build directory,
    not the host compiler or just-built compiler-rt libraries.

We should make a choice on the way we intend ti run compiler-rt lit testsuite:
a) use either Clang from LLVM build tree, or the host compiler.
b) use either just-built runtimes, or the runtimes shipped with the
host compiler.

Using just-built runtimes is tricky - we have to know where to put them, so that
Clang/GCC driver would pick them up (and not overwrite the existing runtimes).
Using a host compiler instead of Clang from LLVM build tree will give us a chance to
run lit tests under GCC (which already has support for several sanitizers).

That is, I tend to make the following choice: if we're in a standalone compiler-rt
build, use host compiler with its set of runtime libraries to run lit tests.
This will effectively decouple "make compiler-rt" and "make check-compiler-rt" in
a standalone build - the latter wouldn't invoke the former. Note that if we decide
to fix LLVM/Clang/compiler-rt build system so that it would configure/build
compiler-rt with just-built Clang (as we do in Makefile-based build), this will not
be a problem - we can add a dependency to ensure that clang/compiler-rt are rebuilt
before running compiler-rt tests.
