+ 
+ PowerPC backend skeleton
+ ------------------------
+ 
+ Someday we'd like to have a PowerPC backend. Unfortunately, this
+ is not yet that day.
+ 
+ This directory contains mainly stubs and placeholders; there is no
+ binary machine code emitter, no assembly writer, and no instruction
+ selector here.  Most of the functions in these files call abort()
+ or fail assertions on purpose, just to reinforce the fact that they
+ don't work.
+ 
+ If you want to use LLVM on the PowerPC *today*, use the C Backend
+ (llvm-dis -c).  It generates C code that you can compile with the
+ native GCC compiler and run.  A distant second choice would be the
+ Interpreter (lli --force-interpreter=true).
+ 
+ A few things *are* really here, including:
+  * PowerPC register file definition in TableGen format
+  * PowerPC definitions of TargetMachine and other target-specific classes 
+ 
+ "Patches," as they say, "are accepted."
