5f8e406838 Classes need to have a prefix name, so that they can be tacked on to the pieces 
that TableGen creates for them, e.g. CodeEmitter, AsmPrinter, etc.

11bf63f84a This is the initial draft of the Compiler Driver documentation. It is not 
worthy of review at this point. There is much thought and content remaining
to be written.

8bf21cd984 Fix stack size processing now that the return address isn't an implied 
push onto the top of the stack like x86, which uses the local area
offset.  This will allow the removal of PowerPCPEI.cpp soon.

b588051065 This isn't a bug, it's a missing feature

c5a25532c7 Fix another really nasty regression that Anshu pointed out. In cases where 
dangling constant users were removed from a function, causing it to be dead,
we never removed the call graph edge from the external node to the function.

In most cases, this didn't cause a problem (by luck).  This should definitely
go into 1.3

0b9b58e550 Add standard print/dump methods to CallGraph classes.

0c29b326fb Two fixes: 
1. Fix a REALLY nasty cyclic replacement issue that Anshu discovered, causing
   nondeterminstic crashes and memory corruption.
2. For performance, don't go inserting constantexpr casts of GV pointers.

This should definitely go into 1.3

7c1f10c49d First version of a manual page for the llvmc compiler driver. This tool is 
being documented before being written to foster discussion about what the
tool should do. Eventually, we'll achieve a decision point at which time
this document forms the requirements for the tool from which it will be
coded.

bbf11b1e1d Changes commited for Nate Begeman: 
Use a PowerPC specific prolog epilog inserter to control where spilled
callee save regs are placed on the stack.
Get rid of implicit return address stack slot, save return address reg
(LR) in appropriate slot
Improve code generated for functions that don't have calls or access
globals


Note from Chris: PowerPCPEI will eventually be eliminated, once the
functionality is merged into CodeGen/PrologEpilogInserter.cpp
