/* Describe __builtin_eh_return */# define EH_RETURN_STACKADJ_RTX gen_rtx_REG (Pmode, LAST_RETVAL_REGNO)# define EH_RETURN_DATA_REGNO(N) ((N) <= (LAST_ARG_REGNO - FIRST_ARG_REGNO)

? (N) + FIRST_ARG_REGNO : INVALID_REGNUM)# define ASM_PREFERRED_EH_DATA_FORMAT(CODE, GLOBAL)

(!flag_pic ? DW_EH_PE_sdata4

/* FIXME: These get expanded to dynamic relocs, which is wrong */

/* : !(GLOBAL) ? DW_EH_PE_pcrel | DW_EH_PE_sdata4 */

: DW_EH_PE_aligned)
