.ENDEPILOG

Marks the end of an epilogue unwind region. This directive doesn't emit a Windows unwind data (WOD) unwind code.

Syntax

.ENDEPILOG

Remarks

Important

This directive is experimental and is subject to change. Enable Unwind Version 3 by using ml64.exe /unwindv3.

.ENDEPILOG is only valid in Unwind Version 3.

• It marks the end of an epilogue region started by .BEGINEPILOG.
• These directives generate unwind metadata (.xdata and .pdata sections) but don't produce executable code.
• Epilogues must contain at least one directive.
• Epilogue directives are mandatory for epilogue unwind code generation. No epilogue unwind codes are emitted without a .BEGINEPILOG/.ENDEPILOG pair.
• It's an error to use epilogue directives outside of the region between .BEGINEPILOG and .ENDEPILOG.

Note

In Unwind Version 1, the directive appears after the corresponding instruction. In Unwind Version 3, the directive appears before the instruction.
