640b9280d5 Since we now have TableGen editing modes for VIM and (X)Emacs, we no longer need
to mark TableGen description files with "C++ mode".

2c4fe5813c No need for a second immediate field if the class already inherits one.

35f19cc7b2 Removed unnecessary assignment (it was taken care by a superclass) and clarified
some comments.

ce14ec3901 * Force all "don't care" bits to 0 so that there are absolutely no unset bits in
the TableGen descriptions; all unset bits are thus errors.
* As a result, found and fixed instructions where some operands were not
  actually assigned into the right portion of the instruction.

2ee9fa11a2 Store instructions are different from other Format 3.1/3.2 instructions in that
they prefer the destination register to be last. Thus, two new classes were made
for them that accomodate for having this layout of operands (F3_1rd, F3_2rd).

13292a3347 * Removed unused classes: the rd field is always mentioned as the last reg.
* Added new classes which start building from rs1, adding rs2, and then rd.
* Fixed order of operands in classes 3.11, 3.12, 3.16, and 3.17 .
* Fixed comments to reflect Real Life (tm).
* Removed "don't care" commented out assignments and dead classes (#if 0).

e085a9d279 Added MOVR (move int reg on register condition), aka comparison with zero.
None of these instructions are actually used in the Sparc backend, so no changes
were required in the instruction selector.

33cc12319c The 'rd' register is consistently mentioned last in instruction definitions.
Created new classes from which instructions inherit their ordering of fields.

c89d256e95 The actual order of parameters in a 2-reg-immediate assembly instructions is
"rs1, imm, rd": most importantly, rd goes last.

9b03633265 Because the format of the shift instructions is `shift r, shcnt, r', the
instructions of format 3.12 and 3.13 cannot inherit from F3rdrs1, because that
implies that the two registers are the first two parameters to the instruction.

Thus I made the instructions inherit from F3rd again, and manually added an rs1
field AFTER the shcnt field in the instruction, which maps to the appropriate
place in the instruction.

The other changes are just elimination of unnecessary spaces.

9604416192 Makefile: Make SparcV9CodeEmitter.inc depend on SparcV9_F*.td as well.
SparcV9_F3.td: F3_12 and F3_13 instructions have rd and rs1 fields. Also,
 their fields were totally screwed up. This seems to fix the problem.

dafa504341 * Broke up SparcV9.td into separate files as it was getting unmanageable
* Added some Format 4 classes, but not instructions
* Added notes on missing sections with FIXMEs
* Added RDCCR instr
