Graduate LLVM to the big leagues by embedding a LISP processor into TableGen.

Ok, not really, but do support some common LISP functions:

* car
* cdr
* null

Implement a !foreach operator analogous to GNU make's $(foreach).
Use it on dags and lists like this:

class decls {
  string name;
}

def Decls : decls;

class B<list<string> names> : A<!foreach(Decls.name, names, !strconcat(Decls.name, ", Sr."))>;

llvm-svn: 71803

Implement a !subst operation simmilar to $(subst) in GNU make to do
def/var/string substitution on generic pattern templates.  For example:

def Type;
def v4f32 : Type;
def TYPE : Type;

class GenType<Type t> {
  let type = !(subst TYPE, v4f32, t);
}

def TheType : GenType<TYPE>;

Implement !cast.

Operation Enhancements

Create an OpInit class to serve as a base for all operation Inits.

Move parsing of operation constructs to separate functions and reference
from multiple places.

Add some commented out new operations.  Coming soon.

llvm-svn: 71789

of "class", so that it matches the subsequent definition.

llvm-svn: 70498

Fix multiclass inheritance to limit value resolution to new defs added
by base multiclasses.  Do not attempt to alter defs from previous base
multiclasses.  This fixes multiple multiclass inheritance.

Make BinOps typed and require a type specifier for !nameconcat.  This
allows binops to be used in typed contexts such as when passing
arguments to classes.

llvm-svn: 69921

Implement !nameconcat to concatenate strings and look up the resulting
name in the symbol table, returning an object.

and as it turns out, cleans up a hack in the Alpha instruction info.

errors when thrown.  This gets us nice errors like this from tblgen:

CMOVL32rr: 	(set GR32:i32:$dst, (X86cmov GR32:$src1, GR32:$src2))
/Users/sabre/llvm/Debug/bin/tblgen: error:
Included from X86.td:116:
Parsing X86InstrInfo.td:922: In CMOVL32rr: X86cmov node requires exactly 4 operands!
def CMOVL32rr : I<0x4C, MRMSrcReg,       // if <s, GR32 = GR32
^

instead of just:

CMOVL32rr: 	(set GR32:i32:$dst, (X86cmov GR32:$src1, GR32:$src2))
/Users/sabre/llvm/Debug/bin/tblgen: In CMOVL32rr: X86cmov node requires exactly 4 operands!

This is all I plan to do with this, but it should be easy enough to improve if anyone 
cares (e.g. keeping more loc info in "dag" expr records in tblgen.

use a SUB instruction instead of an ADD, because -128 can be
encoded in an 8-bit signed immediate field, while +128 can't be.
This avoids the need for a 32-bit immediate field in this case.

A similar optimization applies to 64-bit adds with 0x80000000,
with the 32-bit signed immediate field.

To support this, teach tablegen how to handle 64-bit constants.

llvm-svn: 57663

by its first field, but TableGen doesn't actually enforce creating it that 
way. TableGen sorts the records that will be used to create it by the names 
of the records, not the Name field of those records.

This patch corrects the sort to use the "Name" field of the record as the 
sort key.
