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.

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.

Also, convert C-style comments to C++ and make sure code wraps at 80 cols.

  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.

All CVS history was renamed, the *,v were copied over.  No worries.

(At[3] << 24) is an int type and it is being coerced to uint64_t, it was
getting sign extended, causing us to get FFFFFFFFxxxxxxxx constants all of
the time.

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>
