".apple_types" until we get more buy in from other vendors.

Get rid of some of the no-longer-needed parts of PTXAsmPrinter.

Lay some groundwork for converting to MC-based asm printer. This is the first
of probably many patches to bring the back-end back up-to-date with all of the
recent MC changes.

llvm-svn: 140697

Build on previous patches to successfully distinguish between an M-series and A/R-series MSR and MRS instruction. These take different mask names and have a *slightly* different opcode format.

Add decoder and disassembler tests.

Improvement on the previous patch - successfully distinguish between valid v6m and v7m masks (one is a subset of the other). The patch had to be edited slightly to apply to ToT.

predefines based on the output of GCC as well as the CPU predefines.

Invert tests for __AVX__, Clang's AVX feature is hard coded off still.

Switch Atom from 'SSE3' to 'SSSE3'. This matches GCC's behavior, Intel's
documentation, and ICC's documentation (such as I could dig up).

Switch Athlon and Geode to enable 3dnowa rather than just 3dnow and
nothing (resp.).

automate the process of updating and generating these tests.

If anyone is really interested, I can check my scripts for generating
this test in, but its a horrible pile of shell... Not sure its really
worth it.

fallthrough now that we're working with a switch. Also remove a dubious
"feature" regarding k6 processors and 3dnow and leave a fixme... Not
that anyone is likely to care about correct tuning for k6 processors
with and w/o 3dnow...

selected CPU model to the enumeration. This parses the string
representation once using a StringSwitch on SetCPU. It returns an error
for strings which are not recognized (yay!). Finally it replaces
ridiculous if-chains with switches that cover all enumerators.

The last change required adding several missing entries to the features
function. These were obvious on inspection. Yay for a pattern that gives
warnings when we miss one.

No new test cases yet, as I want to get the 64-bit errors working first.
I'll then start fleshing out the testing more. Currently I'm primarily
testing on Linux, but I'm hoping check whether there are interesting
differences on darwin before long...

wrong, please chime in.

it an error if a CPU is provided for a target that doesn't implement
logic handling CPU settings, to match the ABI settings. It also removes
the CPU parameter from the getDefaultFeatures method. This parameter was
always filled in with the same value as setCPU was called with, and at
this point every single target implementation that referenced the CPU
within this function has needed to store the CPU via setCPU anyways in
order to implement other interface points.

This intrinsic is used to pass the index of the function context to the back-end
for further processing. The back-end is in charge of filling in the rest of the
entries.

The DWARF exception pass uses the call site information, which is set up here. A
pre-RA pass is too late for it to use this information. So create and setup the
function context here, and then insert the call site values here (and map the
call sites for the DWARF EH pass). This is simpler than the original pass, and
doesn't make the CFG lose its SSA-ness.

It's a win-win-win-win-lose-win-win situation.

llvm-svn: 140675

We may need an SjLj EH preparation pass for some call site information, at least
in the short term.

is *very* much a WIP that I'll be refining over the next several
commits, but I need to get this checkpoint in place for sanity.

This also adds a much more comprehensive test for architecture macros,
which is roughly generated by inspecting the behavior of a trunk build
of GCC. It still requires some massaging, but eventually I'll even check
in the script that generates these so that others can use it to append
more tests for more architectures, etc.

Next up is a bunch of simplification of the Targets.cpp code, followed
by a lot more test cases once we can reject invalid architectures.
