Add some data structures to represent for loops. These will be
referenced during object processing to do any needed iteration and
instantiation.
Add foreach keyword support to the lexer.
Add a mode to indicate that we're parsing a foreach loop. This allows
the value parser to early-out when processing the foreach value list.
Add a routine to parse foreach iteration declarations. This is
separate from ParseDeclaration because the type of the named value
(the iterator) doesn't match the type of the initializer value (the
value list). It also needs to add two values to the foreach record:
the iterator and the value list.
Add parsing support for foreach.
Add the code to process foreach loops and create defs based
on iterator values.
Allow foreach loops to be matched at the top level.
When parsing an IDValue check if it is a foreach loop iterator for one
of the active loops. If so, return a VarInit for it.
Add Emacs keyword support for foreach.
Add VIM keyword support for foreach.
Add tests to check foreach operation.
Add TableGen documentation for foreach.
Support foreach with multiple objects.
Support non-braced foreach body with one object.
Do not require types for the foreach declaration. Assume the iterator
type from the iteration list element type.

Providing a template argment to a non-templatized class was crashing
tblgen. Add a diagnostic.
For example,
$ cat bug.td
class A;
def B : A<0> {
}
$ llvm-tblgen bug.td
bug.td:3:11: error: template argument provided to non-template class
def B : A<0> {

Add a paste operator '#' to take two identifier-like strings and joint
them. Internally paste gets represented as a !strconcat() with any
necessary casts to string added.
This will be used to implement basic for loop functionality as in:
for i = [0, 1, 2, 3, 4, 5, 6, 7] {
def R#i : Register<...>
}
llvm-svn: 142525
Stop parsing a value if we are in name parsing mode and we see a left
brace. A left brace indicates the start of an object body when we are
parsing a name.
llvm-svn: 142521
Add a mode control to value and ID parsers. The two modes are:
- Parse a value. Expect the parsed ID to map to an existing object.
- Parse a name. Expect the parsed ID to not map to any existing object.
The first is used when parsing an identifier to be looked up, for
example a record field or template argument. The second is used for
parsing declarations. Paste functionality implies that declarations
can contain arbitrary expressions so we need to be able to call into
the general value parser to parse declarations with paste operators.
So we need a way to parse a value-like thing without expecting that
the result will map to some existing object. This parse mode provides
that.
llvm-svn: 142519
Add a Value named "NAME" to each Record. This will be set to the def or defm
name when instantiating multiclasses. This will replace the #NAME# processing
hack once paste functionality is in place.
llvm-svn: 142518
Allow template arg names to be Inits. This is further work to
implement paste as it allows template names to participate in paste
operations.
llvm-svn: 142500
Convert SetValue to take the value name as an Init. This allows us to
set values for variables whose names are not yet fully resolved.

Multidefs are a bit unwieldy and incomplete. Remove them in favor of
another mechanism, probably for loops.

For consistency, prefix multiclass template arg names with the
multiclass name followed by "::" to avoid name clashes among
multiclass arguments and other entities in the multiclass.
llvm-svn: 141239
Process each multidef declared in a multiclass. Iterate through the
list and instantiate a def in the multiclass for each item, resolving
the list item to the temporary iterator (possibly) used in the
multidef ObjectBody. We then process each generated def in the normal
way.
llvm-svn: 141233
Add parser support to recognize multidefs. No processing on the
multidef is done at this point. The grammar is:
MultiDef = MULTIDEF ObjectName < Value, Declaration, Value > ObjectBody
The first Value must be resolveable to a list and the second Value
must be resolveable to an integer. The Declaration is a temporary
value used as an iterator to refer to list items during processing.
It may be passed into the ObjectBody where it will be substituted with
the list value used to instantiate each def.
llvm-svn: 141232
Move the code to instantiate a multiclass def, bind its arguments and
resolve its members into three helper functions. These will be reused
to support a new kind of multiclass def: a multidef.
