ee54532a92 Add a brief description for the tblgen program. More detail is needed but 
the current author is not the person to provide it. Now that the file
exists, perhaps others will chime in and embellish.

055e4e1fae Major reorganization and extension of the code. The diff on this will be a 
mess as functions were moved around into a better ordering. The code was
extended to provide various -gen-* options to better control what the
generated output should be. Currently it is possible to generate entire
modules (three different ways), functions, global variables, and types.

2d7af150ca Make the getNamedFunction and getNamedGlobal methods be const. They don't 
change the module in any way and we should enforce that.

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.

only transform a shufps to pshufd when the first two operands are the same.

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.

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).
