re PR middle-end/42006 (Termination problem with -O2 and -O3)
2009-11-27 Martin Jambor <mjambor@suse.cz>
PR middle-end/42006
* tree-sra.c (get_replaced_param_substitute): Call create_tmp_var
instead of create_tmp_var. Set DECL_GIMPLE_REG_P to one manually
for vector and complex types.
(get_adjustment_for_base): Describe return value in the comment.
* testsuite/gcc.c-torture/execute/pr42006.c: New test.
