This change makes cmake fail to even run on Darwin with errors
evaluating "$<TARGET_OBJECTS:RTInterception.x86_64>".
This reverts r239955
llvm-svn: 239985
Summary:
Add an interface function which can be used to periodically trigger
leak detection in a long-running process.
NB: The meaning of the kIgnored tag has been changed to allow easy clean-up
between subsequent leak checks. Previously, this tag was applied to explicitly
ignored (i.e. with __lsan_disable() or __lsan_ignore_object()) chunks *and* any
chunks only reachable from those. With this change, it's only applied to
explicitly ignored chunks.

The new parser is a lot stricter about syntax, reports unrecognized
flags, and will make it easier to implemented some of the planned features.
llvm-svn: 226169
Summary:
Always quote suppressions files given to *_OPTIONS.
This will make it not break when given full Windows paths (otherwise,
parsing would stop after the drive's letter + ':').
Also fix one or two cases where the suppression files' extensions were
not *.supp.

This was causing build failures on llvm-clang-lld-x86_64-centos-6.5 for some
reason. Anyway, the new way is better because we no longer rely on std::thread
implementation details.

In the current scheme of things, the call to ThreadStart() in the child
thread is not synchronized with the parent thread. So, if a pointer is passed to
pthread_create, there may be a window of time during which this pointer will not
be discoverable by LSan. I.e. the pthread_create interceptor has already
returneed and thus the pointer is no longer on the parent stack, but we don't
yet know the location of the child stack. This has caused bogus leak reports
(see http://llvm.org/bugs/show_bug.cgi?id=21621/).
This patch makes the pthread_create interceptor wait until the child thread is
properly registered before returning.

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.

We are interested in verifying that -gline-tables-only provides enough
debug information for verbose error reports and symbolized stack traces.

another sanitizer.
A user may run both LSan and LSan+ASan. It is weird to pass path to leak
suppression file (or other common sanitizer flags, like "verbosity") in
"LSAN_OPTIONS" in the first case and in "ASAN_OPTIONS" in the second case.
