      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

      Add loop attribute to Phi node · 8e4997d4
      Matthias Braun authored
      This makes our usage of PhiMs to represent the observable behaviour of
      non-terminating loops more obvious.
      Having an explicit loop Phi constructor also fixes problems with Phi
      getting optimized before the keep edge was added.

      split Sel node into Member and Sel · 36408645
      Matthias Braun authored
      - Compound type selection is performed with Member
      - Array indexing is performed with Sel
      - Instead of the simpleSel constructor functions you can use the normal Member
        constructors now
      - The concept of array element entities has been removed, Sel nodes just
        contain a pointer to the array type now.

      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.
