Subject: Add a temporary hack to FmtElm to truncate 64-bit pointers to 32-bits.
X-Git-Tag: upstream/4.7.83~24184
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4b26e7e5af86064ec0c8f788c38b06b7d390a532;p=platform%2Fupstream%2Fv8.git

Add a temporary hack to FmtElm to truncate 64-bit pointers to 32-bits.

We will have to do some more work to get the code to handle pointers correctly.

Also clean up the constructors, and reduce the long lines.
