Function Documentation

static bool gate_graphite_transforms ( )

static

     Enable -fgraphite pass if any one of the graphite optimization flags
     is turned on.

Referenced by make_pass_graphite().

static void graphite_finalize ( )

static

   Finalize graphite: perform CFG cleanup when NEED_CFG_CLEANUP_P is
   true.

static bool graphite_initialize ( )

static

   Initialize graphite: when there are no loops returns false.

         FIXME: This limit on the number of basic blocks of a function
         should be removed when the SCOP detection is faster.

static void graphite_transform_loops ( )

   Perform a set of linear transforms on the loops of the current
   function.

     If a function is parallel it was most probably already run through graphite
     once. No need to run again.

static unsigned int graphite_transforms ( )

static

static void print_global_statistics ( )

static

   Print global statistics to FILE.

         Ignore artificial surrounding loop.

static void print_graphite_scop_statistics ( )

static

   Print statistics for SCOP to FILE.

static void print_graphite_statistics ( )

static

   Print statistics for SCOPS to FILE.

   This pass converts GIMPLE to GRAPHITE, performs some loop
   transformations and then converts the resulting representation back
   to GIMPLE.

   An early description of this pass can be found in the GCC Summit'06
   paper "GRAPHITE: Polyhedral Analyses and Optimizations for GCC".
   The wiki page http://gcc.gnu.org/wiki/Graphite contains pointers to
   the related work.

   One important document to read is CLooG's internal manual:
   http://repo.or.cz/w/cloog-ppl.git?a=blob_plain;f=doc/cloog.texi;hb=HEAD
   that describes the data structure of loops used in this file, and
   the functions that are used for transforming the code.
