Exit with an error when using
# DP: the Graphite loop transformation infrastructure without having the
# DP: libcloog-ppl0 package installed. Packages using these optimizations
# DP: should build-depend on libcloog-ppl0.
2009-01-27 Jakub Jelinek <jakub@redhat.com>
* Makefile.in (BACKENDLIBS): Link against -ldl instead of -lcloog -lppl.
(graphite.o): Force -O, remove -fkeep-inline-functions.
* graphite.c: Include <dlfcn.h>. Reference libcloog and libppl symbols
through pointers in cloog_pointers variable.
(init_cloog_pointers): New function.
(gcc_type_for_iv_of_clast_loop): Rename stmt_for argument to stmt_fora.
(graphite_transform_loops): Call init_cloog_pointers.
