Misha Brukman 4aab2b25b3 Since we now have TableGen editing modes for VIM and (X)Emacs, we no longer need
to mark TableGen description files with "C++ mode".

Chris Lattner 9fb7e0a425 Transition to using 'let X = y' instead of 'set X = y'.

Misha Brukman d49975cf29 No need for a second immediate field if the class already inherits one.

Misha Brukman 25a49f0cf1 Removed unnecessary assignment (it was taken care by a superclass) and clarified
some comments.

Misha Brukman 20d93ca01d * 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.

Misha Brukman 97a04b24cc Added missing directive to store the instruction name.

Misha Brukman 98467a7a18 Added missing 'rs1' field to F3_rdrs1imm13, 'rd' to F3_rdrs1rs2.

Misha Brukman b54bf54065 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).

Misha Brukman ace89ff224 * 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).

Misha Brukman f545b2402f 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.

Misha Brukman 23937091f0 The 'rd' register is consistently mentioned last in instruction definitions.
Created new classes from which instructions inherit their ordering of fields.

Misha Brukman 87cbd97710 The actual order of parameters in a 2-reg-immediate assembly instructions is
"rs1, imm, rd": most importantly, rd goes last.

Misha Brukman f6e4dce74c 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.

Brian Gaeke d380f29377 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.

Misha Brukman ea4f498395 * 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
