new volume rendering test

tweak

possible bug

tweaked background value

tweaked background value

  Bugfix: missing code when exit was stabilize/die

  minor tweaks.

  Adding test script for zslice-grad example

  Bug fix: get printing format right for vectors

  Bug fix: better CFG editing

  Added support for tracking output state variables through ILs and generating
  a print function in the C target.

  Removed workaround for always stabilizing

  Fixed bug when update always ended in stabilize/die.

  Starting to work on partitioning strand states

  Add stabilize method for strands that don't have them

  Started to add field normalization code to high-opt

  Introduce variable decls into SimpleAST representation.  We need these so that
  the result variables that are introduced for conditional expressions can be
  correctly handled by the translation to SSA.

  fix bug in test program

  test on hand data

  map infs to 0 (instead of -1)

tweaked

simple test of gradient

  order of the voxel vectors

  print range of results for debugging

  bug fix: out and in were backwards

  Preparing to support the rest of the build process in the compiler

  Added comment

   Fixed typos

  Fix file name

  New file

  Use UnixPath module to find dnorm executable

  Use tent filter

  Switch to compiler-generated initially code.

  Working on generating initially code.  Also changed var and exp types in CTarget to
  be datatypes for better typechecking and documentation.

  Added runtime interface to support creation of initial array/collection
  of strands

  Since initially only supports rectangular-shaped iteration, we can lift the range
  computation outside the iterations.  This allows us to determine the dimensions and
  to change the order of loop nesting.

  Fixed a typechecking issue with iteration

  Don't map negative values to 0

  More work on supporting initially in code generation

  Adding for loops to C code generator

  Added ++ and -- as prefix and postfix operators

  Adding support for initially to IL.  Also factored out more common code from
  high-to-mid and mid-to-low into translate-fn.sml

  Added unu stage to handle infs in output

new implementation of inside

  Starting to implement support for initially

correcting affine transform to index space of dataset

  Special case for 0 as a floating-point literal

  Fixed bug in computing coefficients for probes

  Fixed bug in construction of CFG.  The order of predecessors was backwards

  Fixed bug in the handling of assignments to literals

  Added missing new lines and function for printing TreeIL statements

  Fixing pretty printing

  Workaround for the fact that gcc does not handle vec2f_t correctly

  Bug fix: the update function was cast to the wrong type

  Fixed calculation of rr and cc

another for debugging

new test dataset

new test program, for generating an image of the recon kernel
