ARM encodes Q registers as 2xregno (i.e. the number of the D register that corresponds to the lower
...
half of the Q register), rather than with just regno. This allows us to unify the encodings for
a lot of different NEON instrucitons that differ only in whether they have Q or D register operands.

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.
