Author: rth Date: Tue Sep 22 15:11:37 2009 New Revision: 151983 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=151983 Log: PR target/41246 * target.h (struct gcc_target): Add asm_out.trampoline_template, calls.static_chain, calls.trampoline_init, calls.trampoline_adjust_address. * target-def.h (TARGET_ASM_TRAMPOLINE_TEMPLATE): New. (TARGET_STATIC_CHAIN, TARGET_TRAMPOLINE_INIT): New. (TARGET_TRAMPOLINE_ADJUST_ADDRESS): New. * builtins.c (expand_builtin_setjmp_receiver): Use targetm.calls.static_chain; only clobber registers. (expand_builtin_init_trampoline): Use targetm.calls.trampoline_init; set up memory attributes properly for the trampoline block. (expand_builtin_adjust_trampoline): Use targetm.calls.trampoline_adjust_address. * calls.c (prepare_call_address): Add fndecl argument. Use targetm.calls.static_chain. * df-scan.c (df_need_static_chain_reg): Remove. (df_get_entry_block_def_set): Use targetm.calls.static_chain; consolodate static chain handling. * doc/tm.texi: Document new hooks. * emit-rtl.c (static_chain_rtx, static_chain_incoming_rtx): Remove. (init_emit_regs): Don't initialize them. * expr.h (prepare_call_address): Update decl. * final.c (profile_function): Use targetm.calls.static_chain. * function.c (expand_function_start): Likewise. * rtl.h (static_chain_rtx, static_chain_incoming_rtx): Remove. * stmt.c (expand_nl_goto_receiver): Use targetm.calls.static_chain; only clobber registers. * targhooks.c (default_static_chain): New. (default_asm_trampoline_template, default_trampoline_init): New. (default_trampoline_adjust_address): New. * targhooks.h: Declare them. * varasm.c (assemble_trampoline_template): Use targetm.asm_out.trampoline_template. Make the memory block const and set its size.
