auroraux.org is not resolving.
I will add this to the release notes as soon as I figure out where to put the
3.6 release notes :-)

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

Remove the MinGW32 and Cygwin types from the OSType enumeration. These values
are represented via environments of Windows. It is a source of confusion and
needlessly clutters the code. The cost of doing this is that we must sink the
check for them into the normalization code path along with the spelling.
Addresses PR20592.

it breaks the modules builds (where CallGraph.h can be quite reasonably
transitively included by an unimported portion of a module, and CallGraph.cpp
not linked in), and appears to have been entirely redundant since PR780 was
fixed back in 2008.
If this breaks anything, please revert; I have only tested this with a single
configuration, and it's possible that this is still somehow fixing something
(though I doubt it, since no other similar file uses this mechanism any more).

path::const_iterator claims that it's a bidirectional iterator, but it
doesn't satisfy all of the contracts for a bidirectional iterator.
For example, n3376 24.2.5 p6 says "If a and b are both dereferenceable,
then a == b if and only if *a and *b are bound to the same object",
but this doesn't work with how we stash and recreate Components.
This means that our use of reverse_iterator on this type is invalid
and leads to many of the valgrind errors we're hitting, as explained
by Tilmann Scheller here:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20140728/228654.html
Instead, we admit that path::const_iterator is only an input_iterator,
and implement a second input_iterator for path::reverse_iterator (by
changing const_iterator::operator-- to reverse_iterator::operator++).
All of the uses of this just traverse once over the path in one
direction or the other anyway.

On Cygwin, getpagesize() returns 64k(AllocationGranularity).
In r214580, the size of X86GenInstrInfo.inc became 1499136.
FIXME: We should reorganize again getPageSize() on Win32.
MapFile allocates address along AllocationGranularity but view is mapped by physical page.

Instead of moving out the data in a ErrorOr<std::unique_ptr<Foo>>, get
a reference to it.
Thanks to David Blaikie for the suggestion.

Even if there's a file called c:\a, we want /? to be preserved as
an option, not expanded to a filename.

There really is no arm64_be: it was a useful fiction to test big-endian support
while both backends existed in parallel, but now the only platform that uses
the name (iOS) doesn't have a big-endian variant, let alone one called
"arm64_be".
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213748 91177308-0d34-0410-b5e6-96231b3b80d8
Having both Triple::arm64 and Triple::aarch64 is extremely confusing, and
invites bugs where only one is checked. In reality, the only legitimate
difference between the two (arm64 usually means iOS) is also present in the OS
part of the triple and that's what should be checked.
We still parse the "arm64" triple, just canonicalise it to Triple::aarch64, so
there aren't any LLVM-side test changes.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213743 91177308-0d34-0410-b5e6-96231b3b80d8
It's also possible to just write "= nullptr", but there's some question
of whether that's as readable, so I leave it up to authors to pick which
they prefer for now. If we want to discuss standardizing on one or the
other, we can do that at some point in the future.

This is a prerequisite for checking for 'mti' and 'img' in a consistent way in
clang. Previously 'img' could use Triple::getVendor() but 'mti' could only use
Triple::getVendorName().

Re-commit of a patch to rework the triple parsing on ARM to a more sane
model.
Patch by Gabor Ballabas.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213367 91177308-0d34-0410-b5e6-96231b3b80d8
This optional dependency on the udis86 library was added some time back to aid
JIT development, but doesn't make much sense to link into LLVM binaries these
days.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213300 91177308-0d34-0410-b5e6-96231b3b80d8
Triple.cpp still returns "arm64" as prefix for arm64 triple, causing Clang not
being able to select the correct GCCBuiltin IR.
This patch changes the value to correct prefix "aarch64". Regression test will
be added in the coming patch.

On Windows, wildcard expansion isn't performed by the shell, but left to the
program itself. The common way to do this is to link with setargv.obj, which
performs the expansion on argc/argv before main is entered. However, we don't
use argv in Clang on Windows, but instead call GetCommandLineW so we can handle
unicode arguments. This means we have to do wildcard expansion ourselves.
A test case will be added on the Clang side.

The memcpy() and overlap helps didn't help much with timings, so clean up the change.
The difference at this point is that we now leave growth of the storage buffer
up to SmallVector's implementation:
- OS.reserve(OS.capacity() * 2);
+ OS.reserve(OS.size() + 64);
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212837 91177308-0d34-0410-b5e6-96231b3b80d8
Including the scratch buffer size in the initial reservation eliminates the
subsequent malloc+move operation and offers a healthier constant growth with
less memory wastage.
When doing this, take care to avoid invalidating the source buffer.

Turn llvm::SpecialCaseList into a simple class that parses text files in
a specified format and knows nothing about LLVM IR. Move this class into
LLVMSupport library. Implement two users of this class:
* DFSanABIList in DFSan instrumentation pass.
* SanitizerBlacklist in Clang CodeGen library.
The latter will be modified to use actual source-level information from frontend
(source file names) instead of unstable LLVM IR things (LLVM Module identifier).
Remove dependency edge from ClangCodeGen/ClangDriver to LLVMTransformUtils.
No functionality change.

According to a FIXME in ARMMCTargetDesc.cpp the ARM version parsing should be
in the Triple helper class.

Use 0 for the invalid buffer instead of -1/~0 and switch to unsigned
representation to enable more idiomatic usage.
Also introduce a trivial SourceMgr::getMainFileID() instead of hard-coding 0/1
to identify the main file.

Some versions of Android don't have futimes/futimens and this code wasn't
updated during the recent errc refactoring.

where there is no timeout. In the case where there is a timeout though, the
code is still wrong since it doesn't check that the alarm really went off.
Without this patch, I cannot debug a program that forks itself using
sys::ExecuteAndWait with lldb.

I'll fix the problems in libclang and other projects in ways that don't
require <mutex> until we sort out the cygwin situation.
