  The large diff is because of indentation of a whole region
* Fix querying predecessor blocks in SelectPHINodes(), thanks to Brian (v8)
* Add support for external functions malloc() and free()
* Fix some code indentation

Remember, kids: It's not plagiarism if you "creatively borrow" from your
sources.  It's called "research"!

* Fix spacing, grammar in comment
* Make code layout consistent
* Wrap code at 80 cols
* Delete spurious blank lines

No functional changes.

* Non-const FP values must be loaded into int regs (for vararg fns) via memory

llvm-svn: 14701

* Load FP values into int regs as well for vararg functions; without memory ops!

* Add suport for printing out references to constant pool indices

Fix typo in comment.

the top and bottom halves backwards...how embarrassing.
Support 'cast long to long' and other similar no-op casts to long.
Support 'ret long'.

is HOPELESSLY broken.  The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.

As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call.  This fixes some obscure bugs
handling non-forwarded node handles.

* Make visitSetCondInst() share condition-generating code with EmitComparison()
* There are 13 FPRs for function-passing arguments, not 8
* Do not rely on registers being sequential, use an array lookup
* In unimplemented switch cases, send an error and abort instead of silent
  fall-through
* Add doInitialization() for adding function prototypes for external math fns
* Minor changes: fix indentation, spacing, code clarity
