Opcode table order is important.
...
The %ix/get/s instrution disappeared because the code to search the
table expects that the table is sorted. So fix the sort.

Add %ix/getv instruction
...
The %ix/getv instruction loads an integer register directly from
a signal vector. This is an optimization that an index register
is loaded from an expression is only a signal. It avoids the thread
vector space.

Optimize load-add with load/add instruction
...
Where and expression is an immediate value added to a signal value,
it is possible to optimize them to a single instruction that combines
the load with an add at the same time.

Make the modpath source define the VPI modpath object.
...
The modpath source node defines the modpath object, and carries the
nodes for the source expression. The modpath outputs are references
by pointers to the vpiModPath that is not in itself a vpi object
any more. This makes the VPI view of a module path look like the
source-destinaiton pair that is the IEEE1364 description of the
modpath.

Out path term for modpaths
...
Add vvp support for modpath path term outputs. This also introduces
the concept of path terms and moves towards the path term in general
for getting at the endpoits of a modpath.

Clean up modpath vpi interface
...
Clean up rather poorly written modpath vpi support, fixing the
parse of the modpath syntax element to not use pointless globals.
Collect the modpath code into the delay.cc file instead of the
inapropriate vpi_signal.cc source file.

Make vpi_put_value to a real accept an integer value and add diagnostic code.

Modified the code that deals with real variables to accept an integer
value when using vpi_put_value(). Also added some type of diagnostic
message for all switch defaults that have an assert(0) to indicate an
error condition, removed CVS comments and removed a small section of
unreachable code.

The runtime is a vvp runtime engine debug aid that allows for

in the vvp source.
