SH-3 Assembler Macros

SH-3 assembler-level macros isolate the programmer from the details involved with using assembler directives.

For a description of how these macros are implemented using assembler directives, see Hitachi Assembler Directive Example.

The following table shows the macros defined for SH-3 microprocessors.

Macro Name	Description
ALTERNATE_ENTRY	Declares an alternate entry to a routine
END_REGION	Marks the end of a contiguous range of text or data
ENTRY_END	Ends the routine that was specified by a prior NESTED_ENTRY
EXCEPTION_HANDLER_DATA	Associates a named exception handler with the subsequent NESTED_ENTRY
EXCEPTION_HANDLER_DATA	Associates a named exception handler and the handler data with the subsequent NESTED_ENTRY
LEAF_ENTRY	Declares the beginning of a routine that does not require any prolog code
NESTED_ENTRY	Declares the beginning of a routine that either has an existing stack frame or creates a new stack frame
PROLOG_END	Marks the end of the prolog area
START_REGION	Marks the beginning of a contiguous range of text or data
