They behave in accordance with the Has2008 and ABS2008 configuration bits of the processor which are used to select between the 1985 and 2008 versions of IEEE 754. In 1985 mode, these instructions are arithmetic (i.e. they raise invalid operation exceptions when given NaN), in 2008 mode they are non-arithmetic (i.e. they are copies).

nmadd.[ds], and nmsub.[ds] are still subject to -enable-no-nans-fp-math because the ISA spec does not explicitly state that they obey Has2008 and ABS2008.

Fixed the issue with the previous version of this patch (r205628). A pre-existing 'let Predicate =' statement was removing some predicates that were necessary for FP64 to behave correctly.

This adds support in 'opt' to filter pass remarks emitted by
optimization passes. A new flag -pass-remarks specifies which
passes should emit a diagnostic when LLVMContext::emitOptimizationRemark

This will allow the front end to simply pass along the regular

Put a limit on ScheduleDAGSDNodes::ClusterNeighboringLoads to avoid blowing up compile time.

Fixes PR16365 - Extremely slow compilation in -O1 and -O2.

The SD scheduler has a quadratic implementation of load clustering
which absolutely blows up compile time for large blocks with constant
pool loads. The MI scheduler has a better implementation of load
clustering. However, we have not done the work yet to completely
eliminate the SD scheduler. Some benchmarks still seem to benefit from
early load clustering, although maybe by chance.

As an intermediate term fix, I just put a nice limit on the number of
DAG users to search before finding a match. With this limit there are no
binary differences in the LLVM test suite, and the PR16365 test case
does not suffer any compile time impact from this routine.

DebugInfo: Support namespace aliases as DW_TAG_imported_declaration instead of DW_TAG_imported_module

I really should read the spec more often (and test GCC more often too).
I just assumed that namespace aliases would be the same as using
directives, except with a name. But apparently that's not how the DWARF
standards suggests they be implemented. DWARF4 provides an example and
other non-normative text suggesting that namespace aliases be
implemented by named imported declarations intsead of named imported
modules.

So be it.

ARM: consolidate MachO checks for ARM asm parser

This consolidates the duplicated MachO checks in the directive parsing for
various directives that are unsupported for Mach-O.  The error message change is
unimportant as this restores the behaviour to that prior to the addition of the
new directive handling.  Furthermore, use a more direct check for MachO
targeting rather than an indirect feature check of the assembler.

Also simplify the test execution command to avoid temporary files.  Further more,
perform the check in both object and assembly emission.

Whether all non-applicable directives are handled is another question.  .fnstart
is marked as being unsupported, however, the complementary .fnend is not.  The
additional unwinding directives are also still honoured.  This change does not
change that, though, it would be good to validate and mark them as being
unsupported if they are unsupported for the MachO emission.
