Question

Is there any compiler option in MS Visual C++ equivalent to GCC’s -fdump-class-hierarchy? i.e. showing the virtual function table layout.

Answer 1

try

cl.exe /d1reportAllClassLayout test.cpp

The output is something like:

class request_handlerAttribute  size(8):
        +---
 0      | name
 4      | sdl
        +---



class perfmonAttribute  size(8):
        +---
 0      | name
 4      | register
        |  (size=3)
        +---

Found doing:

+ findstr /i class c1xx.dll > c1xx.txt
+ and then manually inspecting c1xx.txt

Hope it can help,
Benedetto

PS: This obviously is an undocumented and unsupported switch.
Look also here for a similar switch.
