to the instruction position. The old encoding would give an absolute ID which counts up within a function, and only resets at the next function. I.e., Instead of having: ... = icmp eq i32 n-1, n-2 br i1 ..., label %bb1, label %bb2 it will now be roughly: ... = icmp eq i32 1, 2 br i1 1, label %bb1, label %bb2 This makes it so that ids remain relatively small and can be encoded in fewer bits. With this encoding, forward reference operands will be given negative-valued IDs. Use signed VBRs for the most common case of forward references, which is phi instructions. To retain backward compatibility we bump the bitcode version from 0 to 1 to distinguish between the different encodings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165739 91177308-0d34-0410-b5e6-96231b3b80d8
