re PR middle-end/38786 ([graphite] ICE with -floop-block in verify_ssa)

2009-01-13  Sebastian Pop  <sebastian.pop@amd.com>

	PR tree-optimization/38786
	* gcc.dg/graphite/pr38786.c: New.
	* graphite.c (expand_scalar_variables_ssa_name): New, outlined from
	the SSA_NAME case of expand_scalar_variables_expr.
	Set the type of an expression to the type of its assign	statement.
	(expand_scalar_variables_expr): Also gather the scalar computation
	used to index the memory access.  Do not pass loop_p.
	Fix comment.  Stop recursion on tcc_constant or tcc_declaration.
	(expand_scalar_variables_stmt): Pass to expand_scalar_variables_expr
	the gimple_stmt_iterator where it inserts new code.  Do not pass loop_p.
	(copy_bb_and_scalar_dependences): Do not pass loop_p.
	(translate_clast): Update call to copy_bb_and_scalar_dependences.
