![]() Initially, slot indexes are quad-spaced. There is room for inserting up to 3 new instructions between the original instructions. When we run out of indexes between two instructions, renumber locally using double-spaced indexes. The original quad-spacing means that we catch up quickly, and we only have to renumber a handful of instructions to get a monotonic sequence. This is much faster than renumbering the whole function as we did before. llvm-svn: 127023 |
