Bug 29507 – Add MarkStackSymbian.cpp to build JavascriptCore for Symbian.

• Component: Platform
• Status: RESOLVED FIXED

[Yongjun Zhang]

MarkStack has platform specific implementations for windows and posix based port.  Symbian port needs to have Symbian specific MarkStack implementation to get JavaScriptCore compile.

add MarkStackSymbian.cpp and reuse windows port's shrinkAllocation().

Re-use Windows shrinkAllocation implementation because Symbian doesn't support releasing part of memory region.      

Use fastMalloc and fastFree to implement allocateStack and releaseStack for Symbian port.

Seems like a lot of headers to include for such a simple .cpp file.  I don't know if fastMalloc/fastFree will behave as you want them to or not.  But I'm happy to r+ a patch with them in it as, you'll figure out very quickly if they're broken. ;)

releaseStack ignores the "size" argument.  Most of WebCore builds with -Wunused enabled, if symbian ever turns that warning back on, this will break.

I'm not sure why Apple's copyright is copied into this tiny file.

I think normally we have an extra line after the corresponding header include, in this case, I would expect a new line after 
+#include "MarkStack.h"

r- for the above mentioned nits.

thanks for the comments, Eric.

In the modified patch, I copied the copyright notice from files in Qt port to keep it consistent.

Then you haven't been paying attention to what is going on in the trunk ;)
That copyright is all over the place in webkit code.

Hi Eric,

I agree the copyright line looks a bit uncommon.  It was however drafted by Nokia/Trolltech legal and is currently used in all Qt port files under WebKit/Qt.

thanks.
