Craig Topper a66d81d521 Teach X86 MC instruction lowering that VMOVAPSrr and other VEX-encoded register to register moves should be switched from using the MRMSrcReg form to the MRMDestReg form if the source register is a 64-bit extended register and the destination register is not. This allows the instruction to be encoded using the 2-byte VEX form instead of the 3-byte VEX form. The GNU assembler has similar behavior.

John McCall e68672fed2 Flag that friend function definitions are "late parsed" so that
template instantiation will still consider them to be definitions
if we instantiate the containing class before we get around
to parsing the friend.

This seems like a legitimate use of "late template parsed" to me,
but I'd appreciate it if someone responsible for the MS feature
would look over this.

This file already appears to access AST nodes directly, which
is arguably not kosher in the parser, but the performance of this
path matters enough that perpetuating the sin is justifiable.
Probably we ought to reconsider this policy for very simple
manipulations like this.

The reason this entire thing is necessary is that
function template instantiation plays some very gross games
in order to not associate an instantiated function template
with the class it came from unless it's a definition, and
the reason *that's* necessary is that the AST currently
cannot represent the instantiation history of individual
function template declarations, but instead tracks it in
common for the entire function template.  That probably
prevents us from correctly reporting ill-formed calls to
ambiguously instantiated friend function templates.

cl::opt'ions. Add a new -default-gcov-version=... option, and actually test it!

Sink the reverse-order of the version into GCOVProfiling, hiding it from our

Rafael Espindola 0e0d00976f Avoid computing the linkage too early. Don't invalidate it.
Before this patch we would compute the linkage lazily and cache it. When the
AST was modified in ways that could change the value, we would invalidate the
cache.

That was fairly brittle, since any code could ask for the a linkage before
the correct value was available.

We should change the API to one where the linkage is computed explicitly and
trying to get it when it is not available asserts.

This patch is a first step in that direction. We still compute the linkage
lazily, but instead of invalidating a cache, we assert that the AST
modifications didn't change the result.

Bill Wendling 965bd58902 Reset some of the target options which affect code generation.
This doesn't reset all of the target options within the TargetOptions

Bill Wendling dabafea7d6 Have these attriubtes set to 'true' or 'false'.
The back-end cannot differentiate between functions that are from a .ll file and
those generated from the front-end. We cannot then take the non-precense of
these attributes as a "false" value. Have the front-end explicitly set the value
to 'true' or 'false' depending upon what is actually set.

Lang Hames dfa3f8f449 Make LTO codegen use a PassManager, rather than a FunctionPassManager, for the
codegen passes. This brings it in to line with clang and llc's codegen setup,
and tidies up the code.

If I understand correctly, adding ModulePasses to a FunctionPassManager is
bogus. It only seems to explode if an added ModulePass depends on a
FunctionPass though, which might be why this code has survived so long.

Fixes <rdar://problem/13386816>.

Argyrios Kyrtzidis b146baabad [Modules] Don't eagerly load and associate all the module header files.
In a module-enabled Cocoa PCH file, we spend a lot of time stat'ing the headers
in order to associate the FileEntries with their modules and support implicit
module import.

Use a more lazy scheme by enhancing HeaderInfoTable to store extra info about
the module that a header belongs to, and associate it with its module only when
there is a request for loading the header info for a particular file.

Argyrios Kyrtzidis 3c5305c15e [Modules] Resolve top-headers of modules lazily.
This allows resolving top-header filenames of modules to FileEntries when
we need them, not eagerly.

Note that that this breaks ABI for libclang functions
clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders
but this is fine because they are experimental and not widely used yet.

Anna Zaks e9989bd4df [analyzer] BugReporter - more precise tracking of C++ references
When BugReporter tracks C++ references involved in a null pointer violation, we
want to differentiate between a null reference and a reference to a null pointer. In the
first case, we want to track the region for the reference location; in the second, we want
to track the null pointer.

In addition, the core creates CXXTempObjectRegion to represent the location of the
C++ reference, so teach FindLastStoreBRVisitor about it.

This helps null pointer suppression to kick in.

(Patch by Anna and Jordan.)
