is listed first and the address is listed second.

7123e27894 Modified the prototypes of the llvm.readport and llvm.writeport intrinsics 
so that they do not specify specific integer sizes (as those are
constrained by the code generator, not the intrinsic itself).

Also put these intrinsics into their own "Operating System" section.

ca6ea0f137 Changes recommended by Chris: 
InstSelectSimple.cpp:
  Change the checks for proper I/O port address size into an exit() instead
  of an assertion.  Assertions aren't used in Release builds, and handling
  this error should be graceful (not that this counts as graceful, but it's
  more graceful).

  Modified the generation of the IN/OUT instructions to have 0 arguments.
X86InstrInfo.td:
  Added the OpSize attribute to the 16 bit IN and OUT instructions.

4ffff9e2fa Added the llvm.readport and llvm.writeport intrinsics for x86. These do 
I/O port instructions on x86.  The specific code sequence is tailored to
the parameters and return value of the intrinsic call.
Added the ability for implicit defintions to be printed in the Instruction
Printer.
Added the ability for RawFrm instruction to print implict uses and
defintions with correct comma output.  This required adjustment to some
methods so that a leading comma would or would not be printed.

9570301ee8 Added the llvm.readport and llvm.writeport intrinsics. 
The Verifier ensures that their parameters are of integral types and have
the correct sign, but it does not enforce any size restrictions because
such restrictions are platform dependent.

775cbdd51a Remove the "really gross hacks" that are there to deal with recursive functions. 
Now we collect all of the call sites we are interested in inlining, then inline
them.  This entirely avoids issues with trying to inline a call site we got by
inlining another call site.  This also eliminates iterator invalidation issues.

d54c38b2f4 It's setting up the call args right now, but on the callee side, it's

4d0cda4d5c This is a start on handling setcc instructions. As the comment notes, we 
have no good way of handling this until the code generator is improved.
We should probably just emit V9 instructions in the meantime.
