it reads its input and runs the passes. The result code signals to the

this is a hack, which may or may not hang around. In short:
whimper out of doing things the Right Way, and hack up a generic

into real (i.e. in tablegen) br.call instructions.

Implement PR512:
This patch adds a -post-link-opts option to llvm-ld which allows an arbitrary
program to optimize bytecode after linking. The program is passed two file
names. The first is the input (linked bytecode) the second is where it must
place its output (presumably after optimizing). If the output file is bytecode,
it is used as a substitute for the input. This will allow things like poolalloc
to be written as a separate program instead of a loadable module or built into
LLVM.

This ugly patch works around a GCC bug where it is compiling SelectCode to
use too much stack space, overflowing the stack for large functions. Instead
of emitting new SDOperands in each match block, we emit some common ones at
the top of SelectCode then reuse them when possible.
This reduces the stack size of SelectCode from 28K to 21K. Note that GCC
compiles it to 512 bytes :-/
I've filed GCC PR 25505 to track this.

Added a break that I meant to include originally, for efficiency. Basically
it keeps it from trying to add the same node to the node set
over and over if it matches multiple given patterns. Also in cases where there
are a lot of patterns to be matched, and it matches an early one, this
will make the script run slightly faster. It's more there because it logically
should be, than anything else, I mean, Python is never going to be fast ;-)

us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register. This also requires some asm printer work
