7ee758d987 Maximally group commands. When all instructions within a command set have a 
series of identical commands, handle them all with one switch.  In the case
of the x86 at&t asm printer, only 3 switches are needed for all instructions.

39569f417f Handle the last operand more intelligently. When emitting the \n, also 
return from the asmprinter to make the generated asmprinter both more
efficient and smaller.

b84950e599 Steal bits from the asm string index to use for operand information. On both 
x86 and ppc, this gets us 4 more bits to play with, since the string indices
both only use 12 bits.

12ac6ac958 Completely change the structure of the generated asmprinter to be more table 
based and less switch-statements-with-hundreds-of-cases based.  This shrinks
the x86 asmprinters to about 1/3 their previous size.

Other improvements coming.

ff3dc2868c Reduce instruction selection code size and stack frame size by factoring 
code that emit target specific nodes into emit functions that are uniquified
and shared among selection routines.
e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame
size of Select_store from ~13k down to ~8k.
This is the first step. Further work to enable more sharing will follow.

e6892852be Emit the string information for the asm writer as a single large string 
and index into it, instead of emitting it like this:

  static const char * const OpStrs[] = {
    "PHINODE\n",        // PHI
    0,  // INLINEASM
    "adc ",     // ADC32mi
    "adc ",     // ADC32mi8
   ...

The old way required thousands of relocations that slows down link time and
dynamic load times.

This also cuts about 10K off each of the X86 asmprinters, and should shrink
the others as well.

88f2956ac8 Don't require src/dst patterns to be able to fully resolve their types, 
because information about one can help refine the other.  This allows us to
write:

def : Pat<(i32 (extload xaddr:$src, i8)),
          (LBZX xaddr:$src)>;

as:

def : Pat<(extload xaddr:$src, i8),
          (LBZX xaddr:$src)>;

because tblgen knows LBZX returns i32.

25273f71bf Make sure to use the result of the pattern to infer the result type of the 
instruction, and the result type of the instruction to refine the pattern.
This allows us to write things like this:

def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (v2i64 VR128:$src)>;

as:
def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)>

and fixes a ppc64 issue.

07d8ccec50 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

accb9d0378 Now that iPTR is a fully resolved type. We end up losing the type check for 
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

will wrap to conform to the window size in which it is displayed instead of

0b5d4a10a9 Allow more loads to be folded which were previously prevented from happening 
due to ordering issue. i.e. they were selected for chain use first.
Now at load select time, check if it is being selected for a chain use and if
it has only a single real use. If so, return a HANDLENODE (with the load as
its operand) in its place and record it.
When it is folded or the load is selected for a real use, the isel records it
as the replacement for the HANDLENODE. The replacement is done when all nodes
are selected.
This scheme exposed a couple of problems where cycles can happen. (See comments
in EmitMatchCode() for descriptions of the problems and their workaround /
solutions.) These problems have been resolved with a small compile time
penality.

7c8bab62e5 (store (op (load ...))) folding problem. In the generated matching code, 
Chain is initially set to the chain operand of store node, when it reaches
load, if it matches the load then Chain is set to the chain operand of the
load.

However, if the matching code that follows this fails, isel moves on to the
next pattern but it does not restore Chain to the chain operand of the store.
So when it tries to match the next store / op / load pattern it would fail on
the Chain == load.getOperand(0) test.

The solution is for each chain operand to get a unique name. e.g. Chain10.

3cdfba635c now that we have control over emission of the code, emit the code using nested 
"if" statements (indenting it appropriately, of course) instead of using goto's.

This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

allows us to indent the code better without touching everything :)

8b6fb0763c Another folding problem: if a node r/w chain or flag, don't fold it if it 
has already been selected. The number of use check is not strong enough since
a node can be replaced with newly created target node. e.g. If the original
node has two uses, when it is selected for one of the uses it is replaced with
another. Each node now has a single use but isel still should not fold it.

Here is an example where the load ended up being done twice:

%A = global uint 0

uint %test(uint %B, ubyte %C) {
	%tmp = load uint *%A;
	%X = shl uint %tmp, ubyte %C
	%Cv = sub ubyte 32, %C
	%Y = shr uint %B, ubyte %Cv
	%Z = or uint %Y, %X
	store uint %Z, uint* %A
	ret uint %Z
}

==>

	subl $4, %esp
	movl %ebx, (%esp)
	movl 8(%esp), %edx
	movl A, %eax
	movb 12(%esp), %bl
	movb %bl, %cl

f168c680e5 Use pattern information to determine whether the use expects this 
instruction to produce a result. e.g MUL8m, the instruction does not
produce a explicit result. However it produces an implicit result in
AL which would be copied to a temp. The root operator of the matching
pattern is a mul so the use would expect it to produce a result.
