SH-4 Assembler Macros
SH-4 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-4 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 |
