Also add leading spaces to the LINK_FLAGS setters, since that's what the cmake
folks recommend: http://www.cmake.org/pipermail/cmake/2012-October/052399.html

The DPR and SPR register lists are also register lists.  Furthermore, the
registers need not be checked individually since the register type can be
checked via the list kind.  Use that to simplify the logic and fix the incorrect
assertion.

In order to provide compatibility with the GNU assembler, provide aliases for
pre-UAL mnemonics for floating point operations.

The vstm family of VFP instructions belong to the VFP store itinerary class, not
the VFP load itinerary class.

[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.

llvm-svn: 198151

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.

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.

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.

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.
