10 years agoFlush C stdio streams upon process termination
Reid Kleckner [Thu, 5 Jun 2014 00:13:43 +0000 (00:13 +0000)]
Flush C stdio streams upon process termination

Due to what can only be described as a CRT bug, stdout and amazingly
even stderr are not always flushed upon process termination, especially
when the system is under high threading pressure.  I have found two
repros for this:

1) In lib\Support\Threading.cpp, change sys::Mutex to an
std::recursive_mutex and run check-clang.  Usually between 30 and 40
tests will fail.

2) Add OutputDebugStrings in code that runs during static initialization
and static shutdown.  This will sometimes generate similar failures.

After a substantial amount of troubleshooting and debugging, I found
that I could reproduce this from the command line without running
check-clang.  Simply make the mutex change described in #1, then
manually run the following command many times by running it once, then
pressing Up -> Enter very quickly:

D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1      -Xclang -error-on-deserialized-decl=TopVar    | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1

Sporadically they will fail, and attaching a debugger to a failed
instance indicates that stdin of FileCheck.exe is empty.

Note that due to the repro in #2, we can rule out a bug in the STL's
mutex implementation, and instead conclude that this is a real flake in
the windows test harness.

Test Plan:
Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run.
With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.

Remove sanitizer blacklist from ASan/TSan/MSan function passes.

Instrumentation passes now use attributes
address_safety/thread_safety/memory_safety which are added by Clang frontend.
Clang parses the blacklist file and adds the attributes accordingly.

Currently blacklist is still used in ASan module pass to disable instrumentation

Fix PR18498: Support explicit template arguments with variadic generic lambdas

This code was resulting in a crash:

auto L = [](auto ... v) { };
L.operator()<int>(3);

The reason is that the partially-substituted-pack is incorrectly retained within the current-instantiation-scope during template-argument-finalization, and because lambda's are local, there parent instantiation scopes are merged, which leads to the expansion-pattern being retained in the finalized specialization.

This patch ensures that once we have finalized deduction of a parameter-pack, we remove the partially-substituted-pack so that it doesn't cause CheckParameterPacksForExpansion to incorrectly inform the caller that it needs to retain the expansion pattern.

Invalidate the file system cache entries for files that may rebuild

I thought we could get away without this, but it means that the
FileEntry objects actually refer to the wrong files, since pcms are not
updated inplace, they are atomically renamed into place after compiling
a module.

So we are close to the original behaviour of invalidating the cache for
all modules being removed, but now we should only invalidate the ones
that depend on whichever module failed to load.

Unfortunately I haven't come up with a new test that didn't require
a race between parallel invocations of clang.

to class members, and forcing emission of exported members. It's based
on Nico Rieck's patch from http://reviews.llvm.org/D1099.

This patch doesn't propagate dllexport to bases that are template
specializations, which is an interesting problem. It also doesn't
look at the rules when redeclaring classes with different attributes,

Fix 'this' capturing Generic lambdas used within default initializers (PR19876)

http://llvm.org/bugs/show_bug.cgi?id=19876

The following C++1y code results in a crash:

struct X {
  int m = 10;
  int n = [this](auto) { return m; }(20);
};

When implicitly instantiating the generic lambda's call operator specialization body, Sema is unable to determine the current 'this' type when transforming the MemberExpr 'm' - since it looks for the nearest enclosing FunctionDeclDC - which is obviously null.

I considered two ways to fix this:

    1) In InstantiateFunctionDefinition, when the context is saved after the lambda scope info is created, retain the 'this' pointer.
    2) Teach getCurrentThisType() to recognize it is within a generic lambda within an NSDMI/default-initializer and return the appropriate this type.

I chose to implement #2 (though I confess I do not have a compelling reason for choosing it over #1).

10 years agoImplement AVX1 vbroadcast intrinsics with vector initializers
Adam Nemet [Thu, 29 May 2014 20:47:29 +0000 (20:47 +0000)]
Implement AVX1 vbroadcast intrinsics with vector initializers

These intrinsics are special because they directly take a memory operand (AVX2
adds the register counterparts).  Typically, other non-memop intrinsics take
registers and then it's left to isel to fold memory operands.

In order to LICM intrinsics directly reading memory, we require that no stores
are in the loop (LICM) or that the folded load accesses constant memory
(MachineLICM).  When neither is the case we fail to hoist a loop-invariant
broadcast.

We can work around this limitation if we expose the load as a regular load and
then just implement the broadcast using the vector initializer syntax.  This
exposes the load to LICM and other optimizations.

At the IR level this is translated into a series of insertelements.  The
sequence is already recognized as a broadcast so there is no impact on the
quality of codegen.

_mm256_broadcast_pd and _mm256_broadcast_ps are not updated by this patch
because right now we lack the DAG-combiner smartness to recover the broadcast
instructions.  This will be tackled in a follow-on.

There will be completing changes on the LLVM side to remove the LLVM
intrinsics and to auto-upgrade bitcode files.
