105d26acb4 Fix conservative assumption, which was quite broken. Also, notice that
functions known to not access memory (like sin/cos) don't access memory! :)

fe98f27e80 Complete rewrite of this pass to be faster, use less memory, be easier to
understand, and more accurate to boot!  This implements
GlobalModRef/purecse.ll over the previous impl.

b0fef64dc9 Add initial support for list slices. This currently allows you to do stuff
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.

a60ff2e144 A utility to run an arbitrary program on each of the LLVM source files.
This is like llvmgrep but instead of running grep, it runs the command
given by the first argument. For example, to find the top ten files with
the most lines in llvm, you could:

utils/llvmdo wc -l | sort -nb | tail

Or, to find any source files with the wrong permissions, you could:

utils/llvmdo ls -l | grep -v rw-r--r--

Hopefully, you get the idea.

3ada3e3f82 ADDI can take several forms, including:
addi r1, r2, 0
  addi r1, <frame index #n>, 0

so we must check for the second parameter being a register for this instruction
to be considered a reg-to-reg copy.

a9d790c831 Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the
glibc 'nan' function because the initializer is not a string.  This breaks when used in a global
initializer.  Try compiling this testcase for example:

%X = global float <some nan value>
