Patchpoints already did this. Doing it for stackmaps is a convenience
for the runtime in the event that it needs to scratch register to
patch or perform a runtime call thunk.

Unlike patchpoints, we just assume the AnyRegCC calling
convention. This is the only language and target independent calling
convention specific to stackmaps so makes sense.  Although the calling
convention is not currently used to select the scratch registers.

Implement LWG #2212: std::is_final. This requires compiler support, which modern versions of clang provide. Also mark LWG #2230 as complete - no code changes needed.

Update synposis in <memory> to show move semantics for weak_ptr; add tests for already existing move semantics. Mark LWG issues #2315 (no changes needed), 2316 (move semantics for weak_ptr), 2252 (previous commit) and 2271 (previous commit) as complete.

selection dag (PR19012)

In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo
to make sure that ESI isn't used as a base pointer register before we choose to
emit rep movs (which clobbers esi).

The problem is that MachineFrameInfo wouldn't know about dynamic allocas or
inline asm that clobbers the stack pointer until SelectionDAGBuilder has
encountered them.

This patch fixes the problem by checking for such things when building the
FunctionLoweringInfo.

The correct name of the type in LLVM assembly is "x86_mmx".  Also remove
the reST label "t_x86mmx" because it was unused anyway.

The distinction between "identified" and "literal" struct types is fully

itself and teach it to convert between the non-const and const variants.
De-templatetize its usage in APIs to just use the const variant which
always works for those use cases. Also, rename its implementation to
reflect that it is an iterator over *users* not over *uses*.

This is a step toward providing both iterator and range support for
walking the *uses* distinct from the *users*. In a subsequent patch this
will get renamed to make it clear that this is an adaptor over the
fundamental use iterator.

I did not intend to cast a pointer to ulittle32_t there because the return
type is const void*.

Looks like llvm-readobj is the only customer of this code, and apparently
there's no test to cover this function. I'll write it after finishing
plumbing from llvm-objdump to there.

Some unreachable code is only "sometimes unreachable" because it
is guarded by a configuration value that is determined at compile
time and is always constant.  Sometimes those represent real bugs,
but often they do not.  This patch causes the reachability analysis
to cover such branches even if they are technically unreachable
in the CFG itself.  There are some conservative heuristics at
play here to determine a "configuration value"; these are intended
to be refined over time.

Summary:
Our usual definition of max_align_t wouldn't match up with MSVC if it
was used in a template argument.

Currently this code is duplicated across visitSHL, visitSRA and visitSRL.  The
plan is to add rotates as clients to this new function.

There is no functional change intended here.
