Why this new error? Or would it have occurred anyway, later? Maybe it
should be an assertion, if it should be impossible. I think "prototypes"
would be better than "protos".

If the use of relative ids was on a per module basis then this wouldn't be
needed.

[LLVMdev] [PATCH / PROPOSAL] bitcode encoding that is ~15% smaller for large bitcode files...
Hi all,
I've been looking into how to make llvm bitcode files smaller. There is
one simple change that appears to shrink linked bitcode files by about 15%.
See this spreadsheet for some rough data:
https://docs.google.com/spreadsheet/ccc?key=0AjRrJHQc4_bddEtJdjdIek5fMDdIdFFIZldZXzdWa0E
The change is in how operand ids are encoded in bitcode files. Rather than
use an "absolute

[LLVMdev] [RFC] Extend LLVM IR to express "fast-math" at a per-instruction level
...local variable in BitcodeWriter.cpp:1814*
I would suspect then you'll also need to provide additional logic for reading:
switch (module_version) {
default: return Error("Unknown bitstream version!");
case 2:
EncodesFastMathIR = true;
case 1:
UseRelativeIDs = true;
break;
case 0:
UseRelativeIDs = false;
break;
}

(*TODO: Put this somewhere else).

Couldn't this be handled by adding an extra operand to the binary operators?
