http://gcc.gnu.org/viewcvs?view=rev&rev=101381 2005-06-28 Andreas Krebbel <[EMAIL PROTECTED]> * config/s390/s390.c (machine_function): New field has_landing_pad_p. (s390_set_has_landing_pad_p, s390_reg_clobbered_rtx, s390_regs_ever_clobbered): New functions. (s390_return_addr_rtx): Use get_hard_reg_initial_value. (s390_register_info, s390_init_frame_layout, s390_update_frame_layout): Use s390_regs_ever_clobbered. (s390_emit_prologue): Don't use r14 as temp reg if its content is used for builtin_return_address. * config/s390/s390.md ("exception_receiver"): New expander. * config/s390/s390-protos.h (s390_set_has_landing_pad_p): Prototype added. Only the following options are needed to reproduce the failure with the reduced testcase: -O1. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24623
