556edf9b9b 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.

88bd79b75b 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.

31b150e334 Always reserve space for 8 spilled GPRs. GCC apparently assumes that this 
space will be available, even if the callee isn't varargs.

2a2457158d 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.

1e1cfbb6fe 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.

9159a7e937 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.

0ce0aa6544 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.

everything except PHI nodes and one odd recurse/opaque type situation.

ce05d51e82 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.

f7637e403f 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

bc04a6c143 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).

bf39add572 Next batch of implementation: 
1. Get rid of old AsmWriter cruft that's not needed.
2. Implement several instructions. Enough to get by globalvars.ll and
   alignment.ll in the Feature test suite.
3. Handle constants properly (don't repeat definitions).
4. Make the output compatible with llvm-dis for diff purposes.

is now theoretically feature-complete.  It has not, however, been thoroughly
test, and is still considered experimental.
