* 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.
