David Greene e917fff30f 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."))>;

David Greene 98ed3c7273 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>;

David Greene 5d0c051e66 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.

David Greene 9d3febea6a Fix PR4207. 
If we're resolving a list element access and we're given a VarInit,
return a new VarListElementInit referencing the VarInit.

David Greene 7049e79e45 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.

David Greene 196ac3c69a 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.

name in the symbol table, returning an object.

Nate Begeman dbe3f77f5b Add support to tablegen for naming the nodes themselves, not just the operands, 
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.

Dan Gohman ca0546facc Fun x86 encoding tricks: when adding an immediate value of 128, 
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.

Evan Cheng 94b5a80b93 Change instruction description to split OperandList into OutOperandList and 
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))]>;

Chris Lattner ef94374a1c Major change to tblgen: instead of resolving values every time a class is 
finished up, only resolve fully when the def is defined.  This allows things
to be changed and all uses to be propagated through.  This implements
TableGen/LazyChange.td and fixes TemplateArgRename.td in the process.

None of the .td files used in LLVM backends are changed at all by this
patch.

llvm-svn: 15249
 2004-07-27 01:01:21 +00:00
Chris Lattner 8bf9e06ddd Add initial support for list slices. This currently allows you to do stuff 
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.
