## T15: V3 with UNW_FLAG_LARGE set.
|
|
## SizeOfProlog is a 16-bit composite (low byte in the header, high byte in
|
|
## the UNWIND_INFO_LARGE_V3 extension which is part of the payload), and
|
|
## prolog IP offsets are 16-bit.

##
|
|
## .xdata hex breakdown:
|
|
## Byte 0: 0x43 (Version=3, Flags=0x08=UNW_FlagLarge)
|
|
## Byte 1: 0x20 (SizeOfProlog low byte: 0x20)
|
|
## Byte 2: 0x04 (PayloadWords=4 words -> 8 bytes payload, includes LARGE byte)
|
|
## Byte 3: 0x02 (NumberOfOps=2, NumberOfEpilogs=0)

## Payload (8 bytes):

## +0: 01 UNWIND_INFO_LARGE_V3: SizeOfPrologHighByte=1 (combined=0x0120=288)
