This requires some gymnastics to make it available for C code. Remove the names
from the disassembler tables, making them relocation free.

Module flags are key-value pairs associated with the module. They include a
'behavior' value, indicating how module flags react when mergine two
files. Normally, it's just the union of the two module flags. But if two module
flags have the same key, then the resulting flags are dictated by the behaviors.

Allowable behaviors are:

     Error
       Emits an error if two values disagree.

     Warning
       Emits a warning if two values disagree.

     Require
       Emits an error when the specified value is not present
       or doesn't have the specified value. It is an error for
       two (or more) llvm.module.flags with the same ID to have
       the Require behavior but different values. There may be
       multiple Require flags per ID.

     Override
       Uses the specified value if the two values disagree. It
       is an error for two (or more) llvm.module.flags with the
       same ID to have the Override behavior but different
       values.

Remove some patterns for matching vector_shuffle instructions since vector_shuffles should be custom lowered before isel.

llvm-svn: 150299

In case the MachineScheduling pass I'm working on doesn't work well
for another target, they can completely override it. This also adds a
hook immediately after the RegAlloc pass to cleanup immediately after
vregs go away. We may want to fold it into the postRA hook later.

llvm-svn: 150298

llvm-svn: 150297

Fix shuffle lowering code to stop creating temporary DAG nodes to do shuffle mask checks on. This seemed to be confusing things such that vector_shuffle ops to got through to iselection. This is another step towards removing the vector_shuffle handling patterns from isel.

llvm-svn: 150296

Implement warning for non-wide string literals with an unexpected encoding.  Downgrade error for non-wide character literals with an unexpected encoding to a warning for compatibility with gcc and older versions of clang.  <rdar://problem/10837678>.

llvm-svn: 150295

simplicity. Also addresses a FIXME, although not one that could be
observed.

llvm-svn: 150294

Basic support for referring to captured variables from lambdas.  Some simple examples seem to work.  Tests coming up soon.

llvm-svn: 150293

Make sure Sema creates a field for 'this' captures.  (Doug, please double-check that this is correct.)

llvm-svn: 150292

a reference for the instantiation decl. Also test that its location is correct
after previous commit.

llvm-svn: 150291

to the pattern template that it came from, otherwise we had this situation:

template <typename T1, typename T2>
struct S {
};

template <typename T>
struct S<T, int> {
};

void f() {
  S<int, int> s; // location of declaration "S<int, int>" was of "S<T1, T2>" not "S<T, int>"
}

"target modules lookup" also work with the
"--function" option, so you can search for
functions that aren't inlined.  This is the
same query that the expression parser makes, so
it's good for diagnosing situations where the
expression parser doesn't find a function you
think should be there.

llvm-svn: 150289

When using register masks, registers like %rip are clobbered by the
register mask. LICM should still be able to hoist instructions reading
%rip from a loop containing calls.

llvm-svn: 150288

Again the goal is to produce identical assembly with register mask
operands enabled.

llvm-svn: 150287

llvm-svn: 150286

prettier.

llvm-svn: 150285

llvm-svn: 150284

Add simple semantic test for C++11 [expr.prim.lambda]p16, which covers recursive capture. This is far more interesting for IRgen.

llvm-svn: 150283

default arguments if in fact those lambdas capture any entity.

Setting UserLabelPrefix correctly fixes PR11949.

llvm-svn: 150280

indicate whether inline functions are desired.
This allows the expression parser, for instance,
to filter out inlined functions when looking for
functions it can call.

llvm-svn: 150279

llvm-svn: 150276

llvm-svn: 150275

Now that the clang driver passes the CPU and feature information to
the backend when processing assembly files (150273), this isn't necessary.

llvm-svn: 150274

When creating the MCSubtargetInfo, the assembler driver uses the CPU and
feature string to construct a more accurate model of what instructions
are and are not legal.

detection of kernels into the object file and
adding a new category for raw binary images.
Fixed all clients who previously searched for
sections manually, making them use the object
file's facilities instead.
