23d171a9ed Add floating-point branches and compares. Compares don't complete 
until the next cycle, and there's no interlock, so they effectively
have a delay slot.

2de292734d Fix bug in copying long constants to register pairs. We were getting 
the top and bottom halves backwards...how embarrassing.
Support 'cast long to long' and other similar no-op casts to long.
Support 'ret long'.

c5d0621e03 An update with corrections to content as well as using a regex style 
notation that Chris' suggested to make the specification more compact and
succinct. Added a section to Describe the notation, made the VBR
description its own section, and otherwise generally cleaned things up.

ab994ac49a The bytecode reader wants to be able to read types that are not quite resolved 
yet, then resolve them in it's own sweet time.  We must support this.

fb2f56c7c8 As much as I hate to say it, the whole setNode interface for DSNodeHandles 
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.

ef78244e72 * Add support for calling vararg functions (must pass doubles in int regs too) 
* 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

f9c3f6178a It doesn't matter what the 2nd operand is; if the GEP has 2 operands and 
the first is a zero, we should leave it alone.

Don't touch GEPs for which DecomposeArrayRef is not going to do anything
special (e.g., < 2 indices, or 2 indices and the last one is a constant.)

e63894ba81 Change the "rotate by 90" xtics specification to just "rotate" which is 
equivalent. The "by <angle>" syntax is not acceptable for all output
devices. Apparently the Sparc and x86 output devices (no color) don't
accept this, but should accept the plain "rotate".

* If SetCondInst is folded into BranchInst (and it is the only user), do not
  emit code for SetCondInst

* Fix codegen of conditional branches

4d6c479f08 Implement InstCombine/sub.ll:test15: X % -Y === X % Y 
Also, remove X % -1 = 0, because it's not true for unsigneds, and the
signed case is superceeded by this new handling.

d450ccbc91 Fix a bug in the unreachable block elim pass. Dropping all references on a 
basic block clear()'s all of the operands lists, including phis.  This
caused removePredecessor to get confused later.  Because of this, we just
nuke (without prejudice) PHI nodes in unreachable blocks.
