<body>
<p>The interface between the ABI-specific backends and the truss
core was refactored, reducing duplicated code. This prompted
additional follow-on work to add support for more ABIs, including
aarch64 and CloudABI.</p>
<p>In addition, ptrace(2) was extended to return more
information about the currently executing system call. This
restored behavior that had been present in a previous verison of
truss of knowing the correct number of arguments for all system
calls.</p>
<p>The fork-following support in truss was reworked to use
native fork following in ptrace(2) rather than forking a new truss
process for each child of a traced process.</p>
<p>Support for decoding more arguments has also been added in
the last quarter as well.
