 *
 * This file contains #defines which configure assembly code emission

/* The following sprintf formats define the mapping of objects in

 * (naming) conventions of the target:
 *	Fortran:
 *		INTEGER X, Y
 *		COMMON /CBLOCK/ X, Y
 *		    =>	loadd	_cblock$,f0		-- load X
 *			loadd	_cblock$+8,f1		-- load Y
 *
 *		CALL SUB()
 *		    =>	call	sp,_sub_
 *
 * The Intrnisic_Proc_Format describes a modification to intrinsic
 * procedure names, allowing an easy way of describing intrinsic
 * naming conventions.  Our convention: Intrinsic functions have
 * an underscore, '_', prepended to their names, so this format is
 * "_%s".  Note that the processing by Intrinsic_Proc_Format is done
 * at compiler-build time (by the program "mkintr.x").
 *
 * Note also that the Ftn_Extern_Proc_Format is *not* applied to
 * intrinsic functions, even though they are external procedures.
 *
 * There are some language-specific things here.  For example, the
 * naming convention for Fortran functions is not the same as the
 * naming convention for C functions.  Consequently, there are two
 * formats for external procedure names:
 *	Ftn_Extern_Proc_Format
 *	C_Extern_Proc_Format
