Parrot on RTEMS - Parrot compiler hints maker

For Google Summer of Code 2010
Bob Kuo

This Makefile will pull all the needed information from an installed RTEMS system and generate:

  * a Parrot hints file (named after your target CPU and BSP, e.g. "sparc_sis.pm") 
  * a "parrot_rtems_config_directives" file which contains all the directives for Parrot's Configure.pl script.

USAGE

1) Grab a copy of parrot and compile for local development system
2) In a separate directory, grab another copy of the parrot source for RTEMS
3) Patch the following files in that source:
   * src/main.c
   * config/gen/makefiles/root.in
   * src/io/socket_api.c
4) Shuffle some source files:
   * mv parrot_rtems/src/main.c parrot_rtems/src/parrot_main.c
   * mv hints_maker/main.c parrot_rtems/src/main.c
   * mv hints_maker/init.c parrot_rtems/src/init.c
   * mv hints_maker/pc386-gdb.* parrot_rtems/src/
5) Run Make to generate the hints file and configuration steps (Make sure that $RTEMS_MAKEFILE_PATH is set correctly)
6) Copy your Parrot hints file into the Parrot source under config/init/hints/.
7) At the top of the Parrot source directory, run:

  perl Configure.pl --file=/path/to/parrot_rtems_config_directives

Replacing /path/to/ with the actual path.
8) Run make miniparrot
