When a test fails with more than a pipeful of output on stdout AND stderr, one
of the DejaGnu programs blocks. The problem can be avoided by redirecting
stdout to a file.

llvm-svn: 71919

The following is checked:

* Operand counts: All explicit operands must be present.

* Register classes: All physical and virtual register operands must be
  compatible with the register class required by the instruction descriptor.

* Register live intervals: Registers must be defined only once, and must be
  defined before use.

The machine code verifier is enabled with the command-line option
'-verify-machineinstrs', or by defining the environment variable
LLVM_VERIFY_MACHINEINSTRS to the name of a file that will receive all the
verifier errors.

logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!

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

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>;

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.

- Use while() instead of do-while().
- Move simple constructors into .h file.
