LLVM backend for 6502

This is still a work in progress. The purpose is to make bundling and unbundling operations explicit, and to catch errors where bundles are broken or created inadvertently. The old IsInsideBundle flag is replaced by two MI flags: BundledPred which has the same meaning as IsInsideBundle, and BundledSucc which is set on instructions that are bundled with a successor. Having two flags provdes redundancy to detect when a bundle is inadvertently torn by a splice() or insert(), and it makes it possible to write bundle iterators that don't need to peek at adjacent instructions. The new flags can't be manipulated directly (once setIsInsideBundle is gone). Instead there are MI functions to make and break bundle bonds. The setIsInsideBundle function will be removed in a future commit. It should be replaced by bundleWithPred(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169583 91177308-0d34-0410-b5e6-96231b3b80d8 |
