let Constraints = "$val = $dst", Defs = [EFLAGS] in, isCodeGenOnly = 1 {

we now get:

Use this to make the X86 and ARM targets set isCodeGenOnly=1 
automatically for their instructions that have Format=Pseudo,
resolving a hack in tblgen.

as the operator of the dag.  Specifically, this allows parsing things
like (F.x 4) in addition to just (a 4).

Unfortunately, this runs afoul of an idiom being used by llvmc.  It
is using dags like (foo [1,2,3]) to represent a list of stuff being
passed into foo.  With this change, this is parsed as a [1,2,3] 
subscript on foo instead of being the first argument to the dag.
Cope with this in the short term by requiring a "-llvmc-temp-hack"
argument to tblgen to get the old parsing behavior.

The rule is simple: only inherit from a class list if they come
in the end, after the last multiclass.

providing more ways to factor out commonality from the records.

Add an !eq() operator to TableGen.  It operates on strings only.
Use !cast<string>() to compare other types of objects.

 - Sorry, I can't help myself.

Improve TableGen error reporting.

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

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

llvm-svn: 73074

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.

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

Allow multiclass def names to contain "#NAME"" where TableGen replaces
#NAME# with the name of the defm instantiating the multiclass.  This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA.  For example:

multiclass SSE_AVX_Inst<...> {
   def SS : Instr<...>;
   def SD : Instr<...>;
   def PS : Instr<...>;
   def PD : Instr<...>;

   def V#NAME#SS : Instr<...>;
   def V#NAME#SD : Instr<...>;
   def V#NAME#PS : Instr<...>;
   def V#NAME#PD : Instr<...>;
}

defm ADD : SSE_AVX_Inst<...>;

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.

Allow defm to inherit from multiple multiclasses.

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