MELT plugin 0.9.7 release candidate 1 for GCC 4.6, 4.7 and future 4.8


Dear All,

It is my pleasure to announce the MELT plugin 0.9.7 release candidate 1 
for GCC 4.6, 4.7 and future 4.8 available on

  http://gcc-melt.org/melt-0.9.7-rc1-plugin-for-gcc-4.6-or-4.7-or-4.8.tar.gz

MELT is a high-level domain specific language to extend GCC and the [meta-]plugin 
providing it. That plugin should work with GCC-4.6, 4.7 and probably the future version 
(unreleased in september 2012) 4.7

Please read more on http://gcc-melt.org/ about MELT. 
Notice that MELT is a language translated to C provding a lot of hooks to GCC. 
Notice also that you can mix MELT and C code in your GCC extensions written in MELT.

MELT is free software GPLv3+ licensed and FSF copyrighted. 
It needs a GCC with plugin enabled to be usable as a plugin.
It is developped on Debian/Linux (amd64).

NEWS for 0.9.7 MELT plugin for GCC 4.6 & 4.7 & future 4.8
[[september, XXth, 2012]]

   Language improvement
   ====================

 When creating an instance with definstance or instance, the
 translator checks that fields are filled with values. Previous
 versions of MELT could crash in that case.

 (CHEADER ...) constructs are working as documented.

 The Parma Polyhedra Library is removed from MELT.

 String values know their length, so safe access to some byte inside
 is possible.

   Added a lot of cmatchers (and implicit primitives) like
	tree_boolean_false_node, tree_boolean_true_node,
	tree_boolean_type_node, tree_char_type_node,
	tree_const_ptr_type_node, tree_double_type_node,
	tree_float_type_node, tree_int128_integer_type_node,
	tree_int128_unsigned_type_node, tree_integer_minus_one_node,
	tree_integer_one_node, tree_integer_type_node,
	tree_integer_zero_node, tree_long_double_type_node,
	tree_long_integer_type_node, tree_long_long_integer_type_node,
	tree_long_long_unsigned_type_node,
	tree_long_unsigned_type_node, tree_null_pointer_node,
	tree_ptr_type_node, tree_short_integer_type_node,
	tree_short_unsigned_type_node, tree_signed_char_type_node,
	tree_size_type_node, tree_unsigned_char_type_node,
	tree_unsigned_type_node, tree_void_type_node
   to access the very built-in trees known to GCC.
   Added more tree & gimple related matchers and primitives.

 Less spurious warnings when building MELT.


   Runtime improvements
   ====================

  Add a runtime expression evaluation function
  TRANSLATE_RUN_MELT_EXPRESSIONS with a mode eval for initial
  evaluation of a sequence of expressions, and a mode repl for
  read-eval-print-loop. (Works by translating these to C code and dlopen-ing it).
  

  The building procedure has been revamped. Advanced users could
  define their GCCMELT_BUILD_NOTIFICATION environment variable to
  e.g. a script meltbuild-notification like

      #! /bin/bash
      # first arg title, second arg message
      if [ "$DISPLAY" = ":0.0" -a -n "$DESKTOP_SESSION" -a $(which notify-send) ]; then
         notify-send -t 3500 -i info "MELT BUILD: $1" "$2"
      else
         logger -t meltbuild -p user.info "$1=" "$2"
      fi

  and they will have a nice bubble notification under most Linux
  desktops of the major steps of the build. The building procedure is
  now quicker than before.

  Advanved MELT users can set their MELTGCC_NO_CHECK_RUNTIME to
  disable checking of the MELT runtime. This is notably needed when
  the MELT plugin is compiled for a cross compiler.

  Advanced MELT users willing to debug with gdb could set the
  melt_alptr_1 and melt_objhash_1 in their gdb debugger to track
  allocation or changes of MELT values or objects.

  The -fmelt-debugging=all option works as expected in the MELT branch
  and so does -fplugin-arg-melt-debugging=all in the MELT plugin.


Numerous bug fixes. The probe has still naughty behavior on large C
source. Consider using Alexandre Lissy's replacement (Python/Qt
based) of the probe.
