[CMake] add_llvm_symbol_exports: Use ${native_export_file} instead of equivalent constant "symbol.*', since it is defined.

This plugs a memory leak in ARM's FastISel by storing the GV in Module so that
it's reclaimed.

The defined() preprocessor expansion wasn't working out on the lld builder.

Also update the documentation to cover another Visual Studio release versioning
convention.

[SparcV9] Use separate instruction patterns for 64 bit arithmetic instructions instead of reusing 32 bit instruction patterns.
 This is done to avoid spilling the result of the 64-bit instructions to a 4-byte slot.

r198153 fixed the msvs bot problem, but broke a msysgit bot. This change
hopefully makes both variants happy.

llvm-svn: 198156

Remove the stat call error reporting for now.

It wasn't essential so silent fallback should be fine here.

The windows ninja build is now green, but msvs is still unhappy. Maybe that's
because the .def file was passed when building LTO_static, so only pass
symbol lists for shared libraries.

Add option -i to prioritize test runs by source file modification time and
previous failure state.

This optimal scheduling reduces typical test-and-fix iteration times to a
matter of seconds by rapidly answering the questions:

  1) Did my recent change fix tests that were previously failing?
  2) Do the tests I just wrote / modified still work?

The current implementation requires write permissions to the source tree
because it uses mtimes to track failures.

[SparcV9] For codegen generated library calls that return float, set inreg flag manually in LowerCall().
 This makes the sparc backend to generate Sparc64 ABI compliant code.

The current quoting is stripped by cmake, try quoting more.

Also prospectively enable static_assert as the documentation suggests it's been
available since MSVC 2010. Let's see if the build servers agree.

llvm-svn: 198142

Includes documentation mapping MSC version numbers to the more familiar Visual
Studio releases.

Cleanup only to simplify upcoming C++11 / MSVC 2013 changes.

The command that cmd.exe is complaining about is:
cmd.exe /c cd /D C:\bb-win7\cmake-clang-i686-mingw32\build\tools\lto && cmake -E echo EXPORTS > symbol.def && type C:/bb-win7/cmake-clang-i686-mingw32/llvm-project/llvm/tools/lto/lto.exports >> symbol.def

Maybe quoting the filename helps.

$ needs to be written $$ in makefiles, but not in cmakefiles.

The cmake build didn't support EXPORTED_SYMBOL_FILE. Instead, it had a
Windows-only implementation in tools/lto/CMakeLists.txt, a linux-only
implementation in tools/gold/CMakeLists.txt, and a darwin-only implementation
in tools/clang/tools/libclang/CMakeLists.txt.

This attempts to consolidate these one-offs into a single place. Clients can now
just set LLVM_EXPORTED_SYMBOL_FILE and things (hopefully) Just Work, like in
the make build.

Directive parsers must return false if the target assembler is interested in
handling the directive.  The Error member function returns true always.  Using
the 'return Error()' pattern would incorrectly indicate to the general parser
that the target was not interested in the directive, when in reality it simply
encountered a badly formed directive or some other error.  This corrects the
behaviour to ensure that the parser behaves appropriately.

It may be a quick and dirty script but it's still useful to have some

This better describes what the function does.

Cleanup only.

'create' functions conventionally return a pointer, not a reference.

Also use an OwningPtr to get replace the delete of a reference member.

No functional change.

llvm-svn: 198126

Schedule more conservatively to account for stalls on floating point
resources and latency. Use the AGU resource to model latency stalls
since it's shared between FP and LD/ST instructions. This might not be
completely accurate but should work well in practice.

Many vector operations never had itineraries. Since the new machine
model was a mapping from existing itinerary classes, we don't have a
model for these. We still want to migrate A9 even though no one has
invested in a complete model, so mark it incomplete to avoid the
scheduler asserting.

llvm-svn: 198123

PostGenericScheduler uses either the new machine model or the hazard
checker for top-down scheduling. Most of the infrastructure for PreRA
machine scheduling is reused.

With a some tuning, this should allow MachineScheduler to be default
for all ARM targets, including cortex-A9, using the new machine
model. Likewise, with additional tuning, it should be able to replace
PostRAScheduler for all targets.

The PostMachineScheduler pass does not currently run the
AntiDepBreaker. There is less need for it on targets that are already
running preRA MachineScheduler. I want to prove it's necessary before
committing to the maintenance burden.

The PostMachineScheduler also currently removes kill flags and adds
them all back later. This is a bit ridiculous. I'd prefer passes to
directly use a liveness utility than rely on flags.

A test case that enables this scheduler will be included in a
subsequent checkin that updates the A9 model.
