Today, I have landed bug 663748 to mozilla-inbound. (Also this will be integrated to mozilla-central today or tomorrow). It means that Win64 build will pass all automation tests. But, since this is for test tool, no effect on Firefox package.
Next Step
- To analyze crash data easily, we have to improve google breakpad for Win64. dumpsym.exe has to add unwind information to symbol file.
- PGO using VS2010. We consider to use VS2010 as official build. Now although we uses VS2008SP1 with PGO options, switching to VS2010SP1 means that we can get more performance. Here is a data how improve to switch to VS2010. But, unfortunately, due to a bug of VS2010, we cannot use 64-bit toolchain. Of course, there is a workaround.
