21.39 FRAME UNWIND ON
The FRAME UNWIND ON directive instructs the assembler to produce unwind tables for this and subsequent functions.
Syntax
FRAME UNWIND ON
Usage
You can use this directive outside functions. In this case,the assembler produces unwind tables for allfollowing functions until it reaches a FRAME UNWIND OFF directive.
Note
A FRAME UNWIND directive is not sufficient to turn on exception table generation. Furthermore a FRAME UNWIND directive, without other FRAME directives, is not sufficient information for the assembler to generate the unwind information.
