X-Git-Tag: android-x86-9.0-r1~523^2~109^2~5
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=662a899ed9bb727c1267ec10d24d87a2f0be3355;p=android-x86%2Fframeworks-native.git

libbinder: Add int64_t/uint64_t to SafeInterface

Adds support for sending and receiving int64_t and uint64_t parameters
as part of a SafeInterface.

Test: New tests in binderSafeInterfaceTest
