;This macro defines the standard tag word before the function,
|
|
;then establishes the statement label with the function's name
|
|
;and finally allocates a register stack frame. It may not be used
|
|
;if a memory stack frame is required.
|
|
;
|
|
;Note also that the size of the register stack frame is limited.
|
|
;Neither this nor the lack of a memory frame is considered to be
|
|
;a severe restriction in an assembly language environment. The
|
|
;assembler will report errors if the requested frame is too large
|
|
;for this macro.

;
|
|
;It may be good practice to allocate an even number of both output
|
|
;registers and local registers. This will help in maintaining
|
|
;double word alignment within these groups. The macro will assure
|
|
;double word alignment of the stack frame as a whole as required
