Ann: MELT plugin 1.3 release candidate 2 for GCC 5 or GCC 6


Dear All,


It is my pleasure to announce the MELT plugin 1.3 release candidate 2 for GCC 5 & GCC 6
(hosted and usable on Linux preferably).

MELT -see http://gcc-melt.org/ for more (or http://starynkevitch.net/Basile/gcc-melt/ which points to the same web pages and resources) - is a domain specific language
and meta-plugin (free software GPLv3+ licensed, FSF copyrighted) to
easily extend and customize the GCC compiler.

Please download the bzip2 compress source tar archive from
  http://gcc-melt.org/melt-1.3-rc2-plugin-for-gcc-5-or-6.tar.bz2
It is a file of 4013849 bytes (3.9Mbytes) and md5sum eb4df214b293caabec07be4a672eda4e

NEWS for 1.3 MELT plugin for GCC 5 & GCC 6
[[may XX, 2016]]

   Bug fixes
   =========

Rare garbage collection bug fixed (noticed with GCC 5).

   Language features
   =================

No significant new language feature.

   Runtime features
   ================

 We did keep compatibility with GCC 5 & GCC 6.

 Since gengtype does not admit conditionals (see messages following
 https://gcc.gnu.org/ml/gcc/2016-02/msg00156.html ...) we had to hack
 our build system. The MELT plugin now use some melt-runtypes.h
 symlink to a version specific file, which has typedef-s like
typedef gimple* melt_gimpleptr_t; // gimple is now a struct

Added plugin options:

   -fplugin-melt-arg-verbose-full-gc: if set to 1 or Y, a message is
   output to stderr on MELT full garbage collections.

   -fplugin-melt-arg-mmap-reserve: don't use it, except to debug the
    MELT runtime. See comment in melt-runtime.cc

The MELT runtime (that it the MELT plugin melt.so) could be built with
-DMELT_HAVE_RUNTIME_DEBUG=1 to enable MELT runtime debugging. This is
rarely useful for MELT users.

################################################################

w.r.t. MELT plugin 1.3 rc1 I have made a few bug fixes (including perhaps some annoying GC bug that I cannot reproduce anymore).

Please try to build & use that release candidate 2 and report bugs to gcc-melt@googlegroups.com

Regards.
