- This manifested as non-determinism in the .inc output in rare cases (when two
   distinct patterns ended up being equivalent, which is rather rare). That
   meant the pattern matching was non-deterministic, which could eventually mean
   the code generator selected different instructions based on the arch.

 - It's probably worth making the DAGISel ensure a total ordering (or force the
   user to), but the simple fix here is to totally order the Record* maps based
   on a unique ID.

 - Sorry, I can't help myself.

 - No intended functionality change.

llvm-svn: 74742

Remove commented code.

llvm-svn: 74471

Implement !cast<string>.

llvm-svn: 74444

Revert 73074 and 73099 because Windows doesn't have POSIX
regular expressions.  We will add an OpenBSD implementation
and re-apply ASAP.

llvm-svn: 73138

Add a !patsubst operator.  Use on string types.

llvm-svn: 73099

Make IntInits and ListInits typed.  This helps deduce types of !if and
other operators.  For the rare cases where a list type cannot be
deduced, provide a []<type> syntax, where <type> is the list element
type.

llvm-svn: 73078

Make !if short-circuit when possible.

llvm-svn: 73076

Add a !regmatch operator to do pattern matching in TableGen.

llvm-svn: 73074

llvm-svn: 71834

Implement !if, analogous to $(if) in GNU make.

llvm-svn: 71815

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

llvm-svn: 71805

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>;

llvm-svn: 71801

Implement !cast.

llvm-svn: 71794

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

Fix PR4207.

If we're resolving a list element access and we're given a VarInit,
return a new VarListElementInit referencing the VarInit.

llvm-svn: 71787

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.

llvm-svn: 69974

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.

llvm-svn: 69822

in selectiondag patterns.  This is required for the upcoming shuffle_vector rewrite,
and as it turns out, cleans up a hack in the Alpha instruction info.

llvm-svn: 67286

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

InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
