Bug 22315 – Adopt check-for-exit-time-destructors on Windows

• Status: NEW
• Component: Tools / Tests

[Adam Roben (:aroben)]

It would be good to adopt the check-for-global-initializers script on Windows. I've done a little investigation into what would have to change in the script to make it work on Windows. Here's what I've come up with (based on <http://trac.webkit.org/browser/trunk/WebKitTools/Scripts/check-for-exit-time-destructors?rev=38476>):

1. Use of Xcode-specific environment variables

We can either set similar variables on Windows or pass the relevant values as parameters.

2. Use of a "link file list"

We can get the list of object files linked into the executable by using "dumpbin.exe /archivemembers".

3. Searching for "___cxa_atexit" to indicate an exit-time destructor

On Windows, "_atexit" is used instead.

4. List of files to skip uses .o extension

On Windows, these files have a .obj extension. We could just use the part of
the filename before the extension instead.

5. Use of otool to disassemble binaries

On Windows, we can use "dumpbin.exe /disasm" instead.

See bug 22314 about adopting check-for-global-initializers as well.

NOTE: Bug 160302 is going to remove these scripts.

However, I think the scripts would have had to use different tools to make them work on Windows.  (Maybe MSVC++ has a switch similar to -Wexit-time-destructors instead?)
