Chris Lattner ae8d67d3bb convert cmp to use a multipattern 
llvm-svn: 115978

Chris Lattner a8c0bbb869 reduce redundancy between pattern copies.

Chris Lattner 9fece2bea2 the opcode for BinOpMI/BinOpMI8 is always the same, remove the argument.

Chris Lattner 752b60bc01 convert adc/sbb to a multipattern. Because the adde/sube nodes 
are not defined as returning EFLAGS (like add_flag and friends),
the entire multipattern and several of the subclasses need to be
cloned.

This could be handled through better instantiation support in tblgen,
but it isn't meta enough.

Chris Lattner 67677515ac add support for isConvertibleToThreeAddress to ArithBinOpEFLAGS, 
allowing us to convert ADD over.  deletes 160 lines of .td file.

Chris Lattner 4fc52f6fa0 Fix a few issues in ArithBinOpEFLAGS that made it specific to and. 
Start using ArithBinOpEFLAGS for OR, XOR, and SUB.

This removes 500 lines from the .td file.  Now AND/OR/XOR/SUB are all
defined exactly the same way instead of being close relatives.

Chris Lattner 26d6a0449a Convert 'and' to single instance of a multipattern 
which instantiates the 34 versions of and all in one
swoop.  The BaseOpc/BaseOpc2/BaseOpc4 stuff should not
be required, but tblgen's feeble brain explodes when I
use Or4<BaseOpc>.V in the multipattern.

No change in the generated .inc files.

Chris Lattner b71a77d7b8 add a new BinOpAI class to represent the immediate form that directly acts on EAX. 
This does change the generated .inc files to include the implicit use/def of eax.
Since these instructions are only generated by the assembler and disassembler it
doesn't actually matter though.

llvm-svn: 115885
 2010-10-07 00:43:39 +00:00
Chris Lattner 894d2e6146 add a bunch of classes for other common patterns. 
As usual, no change in generated .inc files.

 2010-10-07 00:35:28 +00:00
Chris Lattner e17d7212f1 Define a new BinOpRI8 class and use it to define the imm8 versions of and. 
llvm-svn: 115880
 2010-10-07 00:12:45 +00:00
Chris Lattner 356f16c142 add the pattern operator to match to X86TypeInfo, use this to 
convert AND64ri32 to use BinOpRI.

llvm-svn: 115878
 2010-10-07 00:01:39 +00:00
Chris Lattner 6e85be2ecf enhance X86TypeInfo to include information about the encoding and 
operand kind for immediates.  Use these to define a new BinOpRI
class and switch AND8/16/32ri over to it.  AND64ri32 needs some
more refactoring before it can make the switcheroo.

Chris Lattner 94eff91dc0 add a class for _REV nodes. 
llvm-svn: 115748
 2010-10-06 05:35:22 +00:00
Chris Lattner a46073b56b sink more intelligence into the ITy base class. Now it knows 
that i8 operations are even and i16,i32,i64 operations have a
low opcode bit set (they are odd).

 2010-10-06 05:28:38 +00:00
Chris Lattner b6da2be7e8 refactor things a bit, now the REX_W and OpSize prefix bytes are inferred from the type info. 
llvm-svn: 115745
 2010-10-06 05:20:57 +00:00
Chris Lattner 7bbd809b6c with tblgen suitably extended, we can now get the load node from typeinfo.

 2010-10-06 04:58:43 +00:00
Chris Lattner 1fc81e90f7 lets go all meta and define new X86 type wrappers that declare the associated 
gunk that goes along with an MVT (e.g. reg class, preferred load operation,
memory operand)

 2010-10-06 00:45:24 +00:00
Chris Lattner eadaeaab93 introduce a new BinOpRM class and use it to factor AND*rm. This points out 
that I need a heavier handed approach to get ultimate factorization.

llvm-svn: 115726
 2010-10-06 00:30:49 +00:00
Chris Lattner 61ea00b494 allow !strconcat to take more than two operands to eliminate 
!strconcat(!strconcat(!strconcat(!strconcat

Simplify some x86 td files to use it.

Chris Lattner 97b1368ae3 associate the instruction suffix letter with the integer gpr 
register class, and use this to simplify use of BinOpRR.

llvm-svn: 115716
 2010-10-05 23:43:04 +00:00
Chris Lattner 7359194b63 introduce a new BinOpRR class, and convert 4 and instructions to use it. 
llvm-svn: 115715
 2010-10-05 23:32:05 +00:00
Chris Lattner 13111b08fb Replace a gross hack (the MOV64ri_alt instruction) with a slightly less 
gross hack (having the asmmatcher handle the alias).

Chris Lattner ab85ef9e55 distribute the rest of the contents of X86Instr64bit.td out to 
the right places.  X86Instr64bit.td now dies, long live x86-64!

 2010-10-05 20:49:15 +00:00
Chris Lattner 27c763d342 move the rest of the simple 64-bit arithmetic into InstrArithmetic.td

Chris Lattner 182e87caaf rewrote two addr constraints so that they are only set, not set and then nestedly cleared.
