* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | 1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better named. Since it is just a predicate and isn't actually changing any state. 2) Added a missing return in the comments for setCurrentDwarfLoc() in include/llvm/MC/MCContext.h for fix formatting. 3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change state. 4) Simplified the last test in isValidDwarfFileNumber() to just a one line boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115551 91177308-0d34-0410-b5e6-96231b3b80d8
