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 all
following 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.
