There are three types of `DbgVariable`: - alloca variables, created based on the MMI table, - register variables, created based on DBG_VALUE instructions, and - optimized-out variables. This commit reconfigures `DbgVariable` to make it easier to tell which kind we have, and make initialization a little clearer. For MMI/alloca variables, `FrameIndex.size()` must always equal `Expr.size()`, and there shouldn't be an `MInsn`. For register variables (with a `MInsn`), `FrameIndex` must be empty, and `Expr` should have 0 or 1 element depending on whether it has a complex expression (registers with multiple locations use `DebugLocListIndex`). Optimized-out variables shouldn't have any of these fields. Moreover, this separates DBG_VALUE initialization until after the variable is created, simplifying logic in a future commit that changes `collectVariableInfo()` to stop creating empty .debug_loc entries/lists. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@240243 91177308-0d34-0410-b5e6-96231b3b80d8 |
