.. java:type:: public final class CStuff

   C language specific methods.

Methods
-------
buildAllocate
^^^^^^^^^^^^^

.. java:method:: protected static Tree buildAllocate(Tree mallocTree, int typeSize, SymbolTable symbolTable, Instruction instruction)
   :outertype: CStuff

   Builds a transformed copy of the C-syntax mallocTree, using the IL syntax op_allocate

   :param mallocTree: a call to malloc or calloc, possibly enclosed into a cast.
   :return: an op_allocate tree, containing in particular the cast type if present.

buildDeallocate
^^^^^^^^^^^^^^^

.. java:method:: protected static Tree buildDeallocate(Tree callFreeTree)
   :outertype: CStuff

buildIOCall
^^^^^^^^^^^

.. java:method:: protected static Tree buildIOCall(Tree callTree)
   :outertype: CStuff

buildMalloc
^^^^^^^^^^^

.. java:method:: public static Tree buildMalloc(Tree allocateTree, Tree assigned)
   :outertype: CStuff

   Builds a transformed copy of the IL syntax op_allocate, as a C-syntax mallocTree. Decision of the C-style allocation (malloc, calloc, or cudaMalloc) is based the "sourcetree" annotation of the allocateTree.

   :param allocateTree: an op_allocate tree a call to malloc or calloc, possibly enclosed into a cast.
   :param assigned: the variable that receives the allocated memory. Used only when regenerating a cudaMalloc.
   :return: a call to malloc or calloc, possibly enclosed into a cast, or a call to cudaMalloc

buildPow
^^^^^^^^

.. java:method:: protected static Tree buildPow(Tree callPowTree)
   :outertype: CStuff

initCSymbolTable
^^^^^^^^^^^^^^^^

.. java:method:: public static void initCSymbolTable(SymbolTable symbolTable)
   :outertype: CStuff

   Inserts predefined C stuff into this initial symbolTable.

isAFree
^^^^^^^

.. java:method:: protected static boolean isAFree(Tree callTree)
   :outertype: CStuff

isAMalloc
^^^^^^^^^

.. java:method:: protected static boolean isAMalloc(Tree mallocTree)
   :outertype: CStuff

isAPow
^^^^^^

.. java:method:: protected static boolean isAPow(SymbolTable symbolTable, Tree callTree)
   :outertype: CStuff

isAnIoCall
^^^^^^^^^^

.. java:method:: public static boolean isAnIoCall(Tree callTree)
   :outertype: CStuff

isaModifiedFloatFloat
^^^^^^^^^^^^^^^^^^^^^

.. java:method:: protected static boolean isaModifiedFloatFloat(Tree instrOrExpr)
   :outertype: CStuff

   Tests that instrOrExpr is op_modifiedType(op_list[op_ident:"float"], float()) [llh 4Sept2017] This is only because of a bug? introduced by version 6119 that creates "float real"s in C instead of plain "float"s.
