DebugInfo: Don't lose unreferenced non-trivial by-value parameters A FastISel optimization was causing us to emit no information for such parameters & when they go missing we end up emitting a different function type. By avoiding that shortcut we not only get types correct (very important) but also location information (handy) - even if it's only live at the start of a function & may be clobbered later.

DebugInfo: Generalize some tests to handle variations in attribute ordering. In an effort to fix inlined debug info in situations where the out of line definition of a function preceeds any inlined usage, the order in which some attributes are added to subprogram DIEs may change. (in essence, definition-necessary attributes like DW_AT_low_pc/high_pc will be added immediately, but the names, types, and other features will be delayed to module end where they may either be added to the subprogram DIE or instead reference an abstract definition for those values) These tests can be generalized to be resilient to this change. 5 or so tests actually have to be incompatibly changed to cope with this reordering and will go along with the change that affects the order. llvm-svn: 209554

DebugInfo: Refactor some tests to allow DW_AT_name to not be the first attribute in a local variable. In an effort to fix concrete variables referencing abstract origins where the concrete variable preceeds the first inlined usage, the addition of attributes such as name, file, etc will be delayed until the end of the module (to wait to see if any inlined instances have occurred, thus necessitating an abstract definition that the concrete definition should also reference). These test cases don't actually need to care about this ordering of attributes, so update them to be more resilient to such changes coming in the near future. llvm-svn: 210940

DebugInfo: Assert that any CU for which debug_loc lists are emitted, has at least one range. This was coming in weird debug info that had variables (and hence debug_locs) but was in GMLT mode (because it was missing the 13th field of the compile_unit metadata) so no ranges were constructed. We should always have at least one range for any CU with a debug_loc in it - because the range should cover the debug_loc. The assertion just ensures that the "!= 1" range case inside the subsequent loop doesn't get entered for the case where there are no ranges at all, which should never reach here in the first place. llvm-svn: 214939

Debug Info: add an identifier field to DICompositeType. DICompositeType will have an identifier field at position 14. For now, the field is set to null in DIBuilder. For DICompositeTypes where the template argument field (the 13th field) was optional, modify DIBuilder to make sure the template argument field is set. Now DICompositeType has 15 fields. Update DIBuilder to use NULL instead of "i32 0" for null value of a MDNode. Update verifier to check that DICompositeType has 15 fields and the last field is null or a MDString. Update testing cases to include an extra field for DICompositeType. The identifier field will be used by type uniquing so a front end can genearte a DICompositeType with a unique identifer. llvm-svn: 189282
