	* calls.c (compute_argument_block_size): Add argument tree fndecl.
	(OUTGOING_REG_PARM_STACK_SPACE): Add function type argument.
	(emit_library_call_value_1): Add new variable fndecl initialized by
	NULL_TREE. It should be the decl type of orgfun, but this information
	seems not to be available here, so it uses the default calling abi.
	* config/arm/arm.c (arm_return_in_memory): Add fntype argumen.
	* config/arm/arm.h (RETURN_IN_MEMORY): Replace RETURN_IN_MEMORY
	by TARGET_RETURN_IN_MEMORY.

	* config/i386/vx-common.h: Likewise.
	* config/cris/cris.h: Removed #if 0 clause.
	* config/arm/arm-protos.h (arm_return_in_memory): Add fntype
	argument.
	* config/i386/i386-protos.h (ix86_return_in_memory): Add fntype
	argument.
	(ix86_sol10_return_in_memory): Likewise.
	(ix86_i386elf_return_in_memory): New.
	(ix86_i386interix_return_in_memory): New.
	* config/mt/mt-protos.h (mt_return_in_memory): New.
	* config/mt/mt.c: Likewise.
	* config/mt/mt.h (OUTGOING_REG_PARM_STACK_SPACE): Add FNTYPE argument.
	(RETURN_IN_MEMORY):  Replace by TARGET_RETURN_IN_MEMORY.
	* config/bfin/bfin.h: Likewise.
	* config/bfin/bfin-protos.h (bfin_return_in_memory): Add fntype
	argument.
	* config/bfin/bfin.c: Likewise.

	* doc/tm.texi (OUTGOING_REG_PARM_STACK_SPACE): Adjust documentation.
	* expr.c (emit_block_move): Adjust use of OUTGOING_REG_PARM_STACK_SPACE.
	* function.c (STACK_DYNAMIC_OFFSET): Adjust use of
	OUTGOING_REG_PARM_STACK_SPACE.
