@defmac STACK_SLOT_ALIGNMENT (@var{type}, @var{mode}, @var{basic-align})
If defined, a C expression to compute the alignment for stack slot.

addresses have different requirements than other base register uses.

+@defmac MODE_CODE_BASE_REG_CLASS (@var{mode}, @var{address_space}, @var{outer_code}, @var{index_code})
A C expression whose value is the register class to which a valid
-base register must belong. @var{outer_code} and @var{index_code} define the
-context in which the base register occurs. @var{outer_code} is the code of
-the immediately enclosing expression (@code{MEM} for the top level of an
-address, @code{ADDRESS} for something that occurs in an
+base register for a memory reference in mode @var{mode} to address
+space @var{address_space} must belong. @var{outer_code} and @var{index_code}
+define the context in which the base register occurs. @var{outer_code} is
+the code of the immediately enclosing expression (@code{MEM} for the top level
+of an address, @code{ADDRESS} for something that occurs in an
@code{address_operand}). @var{index_code} is the code of the corresponding
index expression if @var{outer_code} is @code{PLUS}; @code{SCRATCH} otherwise.

+A C expression which is nonzero if register number @var{num} is
+suitable for use as a base register in operand addresses, accessing
+memory in mode @var{mode} in address space @var{address_space}.
+This is similar to @code{REGNO_MODE_OK_FOR_BASE_P}, except
that that expression may examine the context in which the register
appears in the memory reference. @var{outer_code} is the code of the
immediately enclosing expression (@code{MEM} if at the top level of the
FRAME_POINTER_REGNUM, ARG_POINTER_REGNUM, and the PIC_OFFSET_TABLE_REGNUM.

@defmac NEXT_OBJC_RUNTIME
-Define this macro to generate code for Objective-C message sending using
-the calling convention of the NeXT system. This calling convention
-involves passing the object, the selector and the method arguments all
-at once to the method-lookup library function.
+Set this macro to 1 to use the "NeXT" Objective-C message sending conventions
+by default. This calling convention involves passing the object, the selector
+and the method arguments all at once to the method-lookup library function.
+This is the usual setting when targeting Darwin/Mac OS X systems, which have
+the NeXT runtime installed.
-The default calling convention passes just the object and the selector
-to the lookup function, which returns a pointer to the method.
+If the macro is set to 0, the "GNU" Objective-C message sending convention
+will be used by default. This convention passes just the object and the
+selector to the method-lookup function, which returns a pointer to the method.
+
+In either case, it remains possible to select code-generation for the alternate
+scheme, by means of compiler command line switches.
