[clang-cl] Fix PCH tests to use x86_64 as target

These tests require x86-registered-target, but they don't force the target as
x86 on the command line, which means they will be run and they might fail when
building the x86 backend on another platform (such as AArch64).

Re: [llvm-branch-commits] [llvm-branch] r276647 - Merging r276479:

[Robinson, Paul via llvm-branch-commits]

Hans, it looks like this merge is incomplete--the trunk patch
also modified test/Feature/optnone-opt.ll and that isn't reflected
in the branch.  We have a 3.9 bot already running and it caught
this.

(Removing the test for GVN Hoisting isn't actually the best tactic
here, I'll fix that on trunk after I get some sleep.)
Thanks,

[MSSA] Fix PR28632 in the 3.9 branch.

The now-removed assertion was really more for initial debugging; it's
perfectly valid (albeit relatively rare) for `Q.Visited.size()` to be
greater than 1,000. A similar patch hasn't been applied to trunk
because the piece of code this assertion was a part of no longer exists
in trunk.

Fix okayed by Danny, merge to 3.9 okayed by Hans.

Huh. I am obviously trying to do too many things at once...
I forgot we merged r276048 into our local release branch and that's the
one showing the failure, not upstream 3.9.

I agree, not important for a disabled pass to obey optnone.  I have the
test sorted out on trunk with r277158; we can leave the branch as it is.

Happy to be of service.  Basic x86_64 Linux on the upstream branch, and
a Windows VS2013 with PS4 target on our local branch.  I'll try to keep
them straight in the future!
Thanks,

Re: [llvm-branch-commits] [lldb] r270065 - Checkout release_38 branches of llvm and clang when building lldb 3.8

[Stephane Sezer via llvm-branch-commits]

Hey Hans,

Yes, `scripts/Xcode/build-llvm.py` is the script that needs to be updated now. 
You can ignore `build-lldb-llvm-clang`.

Re: [llvm-branch-commits] [llvm-branch] r275865 - Updating branches/google/testing to r275480

[Tim Shen via llvm-branch-commits]

To be clear, those are likely source bugs, and the most common failure mode
is like:

A Foo(const TempType& t) {
  return A(&t);  // keeps the pointer to a temporary.
}

const A& a = Foo(MakeTemporary());
// the temporary is gone.

Re: [llvm-branch-commits] [llvm-branch] r275828 - Creating release_39 branch off revision 275826

[Anton Korobeynikov via llvm-branch-commits]

Should be there - I kicked the updates for all the repos.

Note that in general the branches will be created with the first
commit to trunk after the branch point.

[Sema] Fix PR28623.

In atomic builtins, we assumed that the LValue conversion on the first
argument would succeed. So, we would crash given code like:

```
void ovl(char);
void ovl(int);
__atomic_store_n(ovl, 0, 0);
```

This patch makes us not assume that said conversion is successful. :)

 Changes to the MIPS Target
 --
 
- During this release ...
+**During this release the MIPS target has:**
+
+* Enabled the Integrated Assembler by default for all ``mips-*`` and
+  ``mipsel-*`` triples.
+* Significantly improved the Integrated Assembler support for the n64 ABI.
+* Added the Clang frontend ``-mcompact-branches={never,optimal,always}`` option
+  that controls how LLVM generates compact branches for MIPS targets.
+* Improved performance and code size for stack pointer adjustments in functions
+  with large frames.
+* Implemented many instructions from the microMIPS32R6 ISA and added CodeGen
+  support for most of them.
+* Added support for the triple used by Debian Stretch for little endian
+  MIPS64, ie. ``mips64el-linux-gnuabi64``.
+* Removed EABI which was neither tested nor properly supported.
+* Gained the ability to self-host on MIPS32R6.
+* Gained the ability to self-host on MIPS64R2 and MIPS64R6 when using the n64
+  ABI.
+* Added support for the ``LA`` macro in PIC mode for o32.
+* Added support for safestack in compiler-rt.
+* Added support for the MIPS n64 ABI in LLD.
+* Added LLD support for TLS relocations for both o32 and n64 MIPS ABIs.
+
+**The MIPS target has also fixed various bugs including the following notable
+fixes:**
+
+* Delay slots are no longer filled multiple times when either ``-save-temps``
+  or ``-via-file-asm`` are used.
+* Updated n32 and n64 to follow the standard ELF conventions for label prefixes
+  (``.L``), whereas o32 still uses its own (``$``).
+* Properly sign-extend values to GPR width for instructions that expect 32-bit
+  values on 64-bit ISAs.
+* Several fixes for the delay-slot filler pass, including correct
+  forbidden-slot hazard handling.
+* Fixed several errors caught by the machine verifier when turned on for MIPS.
+* Fixed broken predicate for ``SELECT`` patterns in MIPS64.
+* Fixed wrong truncation of memory address for ``LL``/``SC`` seqeuences in
+  MIPS64.
+* Fixed the o32, n32 and n64 handling of ``.cprestore`` directives when inside
+  a ``.set noat`` region by the Integrated Assembler.
+* Fixed the ordering of ``HI``/``LO`` pairs in the relocation table.
+* Fixed the generated ELF ``EFlags`` when Octeon is the target.

[SCEV] Update interface to handle SCEVExpander insert point motion.

Summary:
This is an extension of the fix in r271424.  That fix dealt with builder
insert points being moved by SCEV expansion, but only for the lifetime
of the expand call.  This change modifies the interface so that LSR can
safely call expand multiple times at the same insert point and do the
right thing if one of the expansions decides to move the original insert
point.

This is a fix for PR28719.

[Sema] Fix a crash on variadic enable_if functions.

Currently, when trying to evaluate an enable_if condition, we try to
evaluate all arguments a user passes to a function. Given that we can't
use variadic arguments from said condition anyway, not converting them
is a reasonable thing to do. So, this patch makes us ignore any varargs
when attempting to check an enable_if condition.

We'd crash because, in order to convert an argument, we need its
ParmVarDecl. Variadic arguments don't have ParmVarDecls.
