226368ff4e 1. No need to thwart this test with an environment variable. Turning it off 
is the default and handled by the makefile system and runtest
2. Redirect stderr of llvm-as and llvm2cpp so that warning messages about
   instrinsics don't cause Tcl to report the run as failed.

a0eaf2d0c5 Somehow I lost a condition when I was shuffling some code around. Anyway, 
only transform a shufps to pshufd when the first two operands are the same.

15f7e01065 Fix more bugs. This version now passes all of the Feature test except for 
a floating point conversion problem with NAN in intrinsics.ll. llvm2cpp
makes an attempt to provide the correct conversion, based on the
implementation in the CBackend writer, but it doesn't get NAN correct.

461bed2b75 Provide a simpler interface for getting a ConstantArray from a character 
string. Instead of specifying the length, just specify whether the user
wants a terminating null or not. The default is "true" to retain the same
behavior as previously provided by this function.

dd0f8df161 Undo a patch that breaks llvm-as because the warning message is written to 
stdout when the output of llvm-as is also written to stdout. We'll have to
fix tcl some other way.

c02af8538b Write the WARNING message to cout instead of cerr. Writing to cerr causes 
Tcl to claim that the program had an error and thus produces errors in
the dejagnu testing when its really just a warning.

8949477ae4 Adjust the interface to ConstantArray::get. The previous 
implementation always added a null byte to the end of the string. It turns
out that this is not always wanted. By adding a length parameter we preserve
this behavior when length==0 (default value) but also allow other lengths
(not null terminated) to be created.

e6ad27e917 A addressing mode folding enhancement: 
Fold c2 in (x << c1) | c2 where (c2 < c1)
e.g.
int test(int x) {
  return (x << 3) + 7;
}

This can be codegen'd as:
leal 7(,%eax,8), %eax

632cd52162 Since there was interest on the mailing list, this is a utility pass that 
uses DSA to make find targets of calls.  It provides a very convinient
interface to DSA results to do things with indirect calls, such as
write a devirtualizer (which I have and may commit one of these days).

1. Get rid of old AsmWriter cruft that's not needed.
2. Implement several instructions. Enough to get by globalvars.ll and

3. Handle constants properly (don't repeat definitions).
4. Make the output compatible with llvm-dis for diff purposes.
