      Cleanup after def92e0a · 7c907708
      Matthias Braun authored
      Properly use get_irn_pinned/set_irn_pinned as bool value instead of
      comparing setting the ir_op enum values.

      The start block is not special anymore · 0a4ee3b2
      Matthias Braun authored
      The start block is not special block without any "real" instructions
      anymore. In particular this means:
      
      - There is no X_initial_exec Proj from the Start node anymore, "normal"
        cfopts are used for jumping out of the start block.
      - The backend never had the special convention of the start block not
        containing actual code and used to fixup this discrpancy, no more
        fixup code needed now.
      - The part_block() code got a bit more complicated because splitting the
        start block is tricky (previously part_block() simply failed in this
        case but was never used in the Start block because of its special
        convention)

      put irg link directly into node attributs · f3209aa8
      Matthias Braun authored
      The previous approach put the irg link into the block attributes, so
      while saving memory an extra indirection was necessary. Some testing
      with valgrind massif+callgrind revealed that a direct link increses peak
      memory usage by ~1% while also increasing runtime by ~1%. More
      importantly the code gets a bit simpler and some strange corner cases can be
      removed with the direct link.

      cleanup special tarval and Unknown usage · af666143
      Matthias Braun authored
      This commit does:
      - Remove tarval_reachable+tarval_unreachable, dataflow analysis rather
        use top/bottom instead of other special values.
      - Rename tarval_undefined to tarval_unknown as it corresponds to the
        Unknown node (=a value which we don't know)
      - Remove predefined tarval_top/tarval_bottom from tv.h and place the
        defines into combo.c
      - Change compute_XXX constant folding functions to return tarval_unknown
        instead of tarval_bad if folding failed
      - compute_Unknown in combo results in tarval_bottom == tarval_unknown
        this eliminates strange special cases in the Cond/Switch rules and the
        now unnecessary cprop_X list.

      remove NEW_ARR_A and use ALLOCAN · fee5ce04
      Matthias Braun authored
      All users of NEW_ARR_A used it to construct a simple array, yet noone
      cared about it actually being an array with a length field in front. For
      this simple use case you should use ALLOCAN.

      Alloc/Free only operate on the stack now · 8fda947f
      Matthias Braun authored
      They are considered low level operations now which just allocate/free a
      block of memory on the stack. There is no highlevel typeinformation
      attached anymore or support for heap allocation. Frontends/liboo should
      provide their custom highlevel nodes if they need these features.

      do not include config.h anymore · 0f73b43e
      Matthias Braun authored
      It has been empty for nearly all systems. People who used to put stuff
      in config.h can still create a config.h on their own and inject
      -include (gcc) or /FI (msvc) into their CPPFLAGS.

      remove the concept of a strictconv · 31b3daf7
      Matthias Braun authored
      This means floatingpoint calculation in a firm graph must be performed
      in the mode specified (and may not be performed in a wider mode as
      before).

      split graph state into properties and constraints · b2008e0b
      Matthias Braun authored
      graph_properties are things that a transformation may destroy but which
      can be easily recalculated.
      
      graph_constraints are set after lowering phases have been running and
      forbid certain constructs that no (later) transformation is allowed to construct
