indicate that no catch object should be initialized.

Really all these tests are checking is that we find a file path. The
behavior when we don't find one will have `"ps4-ld"` in it. We just need
a path separator to know that a path has been found.

The root cause of the flakiness of these tests is the same on Windows
and non-Windows: setting the PATH environment variable is not sufficient
to guarantee that a particular path is looked up first.
Driver::GetProgramPath checks some paths before deferring to PATH
(in particular, the directory containing the clang binary itself).

Devin Coughlin [Mon, 29 Feb 2016 21:44:08 +0000 (21:44 +0000)]
[analyzer] Don't treat calls to system headers as escaping in CheckObjCDealloc.

This prevents false negatives when a -dealloc method, for example, removes itself as
as an observer with [[NSNotificationCenter defaultCenter] removeObserver:self]. It is
unlikely that passing 'self' to a system header method will release 'self''s instance
variables, so this is unlikely to produce false positives.

A challenge here is that while CheckObjCDealloc no longer treats these calls as
escaping, the rest of the analyzer still does. In particular, this means that loads
from the same instance variable before and after a call to a system header will
result in different symbols being loaded by the region store. To account for this,
the checker now treats different ivar symbols with the same instance and ivar decl as
the same for the purpose of release checking and more eagerly removes a release
requirement when an instance variable is assumed to be nil. This was not needed before
because when an ivar escaped its release requirement was always removed -- now the
requirement is not removed for calls to system headers.

NFC:  Refactor ProcessWinMiniDump to use a more traditional pimpl idiom.

This is a mechanical refactor.  There should be no functional changes in this commit.

Instead of encapsulating just the Windows-specific data, ProcessWinMiniDump now uses a private implementation class.  This reduces indirections (in the source).  It makes it easier to add private helper methods without touching the header and allows them to have platform-specific types as parameters.  The only trick was that the pimpl class needed a back pointer in order to call a couple methods.

Fix TestInlines.py on Windows

The inlining semantics for C and C++ are different, which affects the test's expectation of the number of times the function should appear in the binary.  In the case of this test, C semantics means there should be three instances of inner_inline, while C++ semantics means there should be only two.

On Windows, clang uses C++ inline semantics even for C code, and there doesn't seem to be a combination of compiler flags to avoid this.

So, for consistency, I've recast the test to use C++ everywhere.  Since the test resided under lang/c, it seemed appropriate to move it to lang/cpp.

This does not address the other XFAIL for this test on Linux/gcc.  See https://llvm.org/bugs/show_bug.cgi?id=26710

Summary:
I re-benchmarked this and results are similar to original results in
D13259:

On ARM64:
  SingleSource/Benchmarks/Polybench/linear-algebra/solvers/dynprog -59.27%
  SingleSource/Benchmarks/Polybench/stencils/adi                   -19.78%

On x86:
  SingleSource/Benchmarks/Polybench/linear-algebra/solvers/dynprog  -27.14%

And of course the original ~20% gain on SPECint_2006/456.hmmer with Loop
Distribution.

In terms of compile time, there is ~5% increase on both
SingleSource/Benchmarks/Misc/oourafft and
SingleSource/Benchmarks/Linkpack/linkpack-pc.  These are both very tiny
loop-intensive programs where SCEV computations dominates compile time.

The reason that time spent in SCEV increases has to do with the design
of the old pass manager.  If a transform pass does not preserve an
analysis we *invalidate* the analysis even if there was *no*
modification made by the transform pass.

This means that currently we don't take advantage of LLE and LV sharing
the same analysis (LAA) and unfortunately we recompute LAA *and* SCEV
for LLE.

(There should be a way to work around this limitation in the case of
SCEV and LAA since both compute things on demand and internally cache
their result.  Thus we could pretend that transform passes preserve
these analyses and manually invalidate them upon actual modification.
On the other hand the new pass manager is supposed to solve so I am not
sure if this is worthwhile.)

by adding additional arguments to _setjmp3: the desired try-state and

[asan] Re-enable test/asan/TestCases/Linux/recvfrom.cc testcase.

This testcase failed on sanitizer-x86_64-linux buildbot in large parallel build due to race on
port 1234 between AddressSanitizer-i386-linux and AddressSanitizer-x86_64-linux instances of recvfrom.cc.
This patch tries to resolve the issue by relying on kernel to choose available port instead of hardcoding
its number in testcase.

8 years agoScopInfo: Remove indentation in hoistInvariantLoads
Tobias Grosser [Mon, 29 Feb 2016 07:29:42 +0000 (07:29 +0000)]
ScopInfo: Remove indentation in hoistInvariantLoads

We move verifyInvariantLoads out of this function to allow for an early return
without the need for code duplication. A similar transformation was suggested
by Johannes Doerfert in post commit review of r262033.
