Adding initial AsmParser implementation for the MBlaze backend. It is
...
mostly based on the ARM AsmParser at this time and is not particularly
functional.
Changed the MBlaze data layout from:
"E-p:32:32-i8:8:8-i16:16:16-i64:32:32-f64:32:32-v64:32:32-v128:32:32-n32"
to:
"E-p:32:32:32-i8:8:8-i16:16:16"
because the MicroBlaze doesn't have i64, f64, v64, or v128 data types.
Cleaned up the MBlaze source code:
1. The floating point register class has been removed. The
MicroBlaze does not have floating point registers. Floating
point values are simply stored in integer registers.
2. Renaming the CPURegs register class to GPR to reflect the
standard naming.
3. Removing a lot of stale code from AsmPrinter after
the conversion to InstPrinter.
4. Simplified sign extended loads by marking them as
expanded in ISelLowering.

Major update of the MicroBlaze backend. The new features are:
...
1. A delay slot filler that searches for valid instructions
to fill the delay slot with. Previously NOPs would always
be inserted into delay slots.
2. Support for MC based instruction printer added.
3. Support for MC based machine code generation and ELF
file generation. ELF file generation does not yet
completely work as much of the ELF support infrastructure
is still x86/x86-64 specific.
4. General clean up of the MBlaze backend code. Much of the
tablegen code has been cleanup and simplified.
Bug Fixes:
1. Removed duplicate periods from subtarget feature descriptions.
2. Many of the instructions had bad machine code information
in the tablegen files. Much of this has been fixed.

Fixing r116753 r116756 r116777
...
The failures in r116753 r116756 were caused by a python issue -
Python likes to append 'L' suffix to stringified numbers if the number
is larger than a machine int. Unfortunately, this causes a divergence of
behavior between 32 and 64 bit python versions.
I re-crafted elf-dump/common_dump to take care of these issues by:
1. always printing 0x (makes for easy sed/regex)
2. always print fixed length (exactly 2 + numBits/4 digits long)
by mod ((2^numBits) - 1)
3. left-padded with '0'
There is a residual common routine that is also used by
macho-dump (dataToHex) , so I left the 'section_data' test values alone.

Get rid of static constructors for pass registration. Instead, every pass exposes an initializeMyPassFunction(), which
...
must be called in the pass's constructor. This function uses static dependency declarations to recursively initialize
the pass's dependencies.
Clients that only create passes through the createFooPass() APIs will require no changes. Clients that want to use the
CommandLine options for passes will need to manually call the appropriate initialization functions in PassInitialization.h
before parsing commandline arguments.
I have tested this with all standard configurations of clang and llvm-gcc on Darwin. It is possible that there are problems
with the static dependencies that will only be visible with non-standard options. If you encounter any crash in pass
registration/creation, please send the testcase to me directly.

"long latency" enough to hoist even if it may increase spilling. Reloading
a value from spill slot is often cheaper than performing an expensive
computation in the loop. For X86, that means machine LICM will hoist
SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON
instructions.

ARM instructions that are both predicated and set the condition codes

have been printed with the "S" modifier after the predicate. With ARM's

ARM. Apparently we don't generate these instructions often because no one
noticed until now. Thanks to Bill Wendling for the testcase!

All registers created during splitting or spilling are assigned to the same

Only split around a loop if the live range has uses outside the loop periphery.

Before we would also split around a loop if any peripheral block had multiple

Add support for vmov.f64/.f32 encoding. There's a bit of a hack going on

here. The f32 in FCONSTS is handled as a double instead of a float in the
code. So the encoding of the immediate into the instruction isn't exactly in
line with the documentation in that regard. But given that we know it's handled
as a double, it doesn't cause any harm.
