re PR regression/40001 (r146817 broke libgloss build for SPU)
2009-05-02 Richard Guenther <rguenther@suse.de>
PR middle-end/40001
* tree-ssa.c (execute_update_addresses_taken): Properly check
if we can mark a variable DECL_GIMPLE_REG_P.
* gimple.c (is_gimple_reg): Re-order check for DECL_GIMPLE_REG_P
back to the end of the function.
(is_gimple_reg_type): Remove complex type special casing.
* gimplify.c (gimplify_bind_expr): Do not set DECL_GIMPLE_REG_P
if not optimizing.
* gcc.target/spu/pr40001.c: New testcase.
