SH-4 Assembler Macros (Windows Embedded CE 6.0)

1/5/2010

SH-4 assembler-level macros are reuired to implement prolog and epilog code sequences.

The following table shows the macros defined for SH-4 microprocessors, which are defined in Kxshx.h.

Macro name	Description
ALTERNATE_ENTRY (SH-4)	Declares an alternate entry to a routine.
END_REGION (SH-4)	Marks the end of a contiguous range of text or data.
ENTRY_END (SH-4)	Ends the routine that was specified by a prior NESTED_ENTRY.
EXCEPTION_HANDLER (SH-4)	Associates a named exception handler with the subsequent NESTED_ENTRY.
EXCEPTION_HANDLER_DATA (SH-4)	Associates a named exception handler and the handler data with the subsequent NESTED_ENTRY.
LEAF_ENTRY (SH-4)	Declares the beginning of a routine that does not require any prolog code.
NESTED_ENTRY (SH-4)	Declares the beginning of a routine that either has an existing stack frame or creates a new stack frame.
PROLOG_END (SH-4)	Marks the end of the prolog area.
START_REGION (SH-4)	Marks the beginning of a contiguous range of text or data.
