Make CVTDQ2PS instruction use SSE2 predicate instead of SSE1. No functional change because there are no patterns in the instructions. Also fix a typo in a comment.

llvm-svn: 159087

Move CVTPD2DQ to use SSE2 predicate instead of SSE3. Move DQ2PD and PD2DQ to the SSE2 section of the file.

This adds support for the tls_model attribute. This allows the user to
choose a TLS model that is better than what LLVM would select by
default. For example, a variable might be declared as:

  __thread int x __attribute__((tls_model("initial-exec")));

if it will not be used in a shared library that is dlopen'ed.

This depends on LLVM r159077.

llvm-svn: 159078

This allows the user/front-end to specify a model that is better
than what LLVM would choose by default. For example, a variable
might be declared as

  @x = thread_local(initialexec) global i32 42

if it will not be used in a shared library that is dlopen'ed.

If the specified model isn't supported by the target, or if LLVM can
make a better choice, a different model may be used.

Optimized usage of new SwitchInst case values (IntegersSubset type) in Local.cpp, Execution.cpp and BitcodeWriter.cpp.
I got about 1% of compile-time improvement on my machines (Ubuntu 11.10 i386 and Ubuntu 12.04 x64).

attributes in more places where we didn't and catching a lot more issues.

This implements nearly every aspect of C++11 attribute parsing, except for:
 - Attributes are permitted on explicit instantiations inside the declarator
   (but not preceding the decl-spec)
 - Attributes are permitted on friend declarations of functions.
 - Multiple instances of the same attribute in an attribute-list (e.g.
   [[noreturn, noreturn]], not [[noreturn]] [[noreturn]] which is conforming)
   are allowed.
The first two are marked as expected-FIXME in the test file and the latter
is probably a defect and is currently untested.

Thanks to Richard Smith for providing the lion's share of the testcases.

Remove intrinsic specific instructions for 128-bit (V)CVTDQ2PD. Replace with intrinsic patterns. Mem forms omitted because the load size is only 64-bits.

It's simple: Don't treat <undef> operands as uses, and don't assume a
virtual register has a defining instruction unless a real use has been
seen.

Heavily based on a patch from
Aaron Wishnick <aaron.s.wishnick@gmail.com>.

I'll clean up the duplicated function in CodeGen as
a follow-up, later today or tomorrow.

There are patterns to handle immediates when they fit in the immediate field.
e.g. %sub = add i32 %x, -123
=>   sub r0, r0, #123
Add patterns to catch immediates that do not fit but should be materialized
with a single movw instruction rather than movw + movt pair.
e.g. %sub = add i32 %x, -65535
=>   movw r1, #65535
     sub r0, r0, r1

As an example of how the custom DiagnosticType can be used to provide
better operand-mismatch diagnostics, add a custom diagnostic for
the imm0_15 operand class used for several system instructions.
Update the tests to expect the improved diagnostic.

rdar://8987109

llvm-svn: 159051

"Invalid operand" may be a completely correct diagnostic, but it's often
insufficiently specific to really help identify and fix the problem in
assembly source. Allow a target to specify a more-specific diagnostic kind
for each AsmOperandClass derived definition and use that to provide
more detailed diagnostics when an operant of that class resulted in a
match failure.
