Stephen Williams f94a655121 Yet again, try to fix vec4 calculation of n-dimensional array index. 2014-01-18 16:04:25 -08:00
Stephen Williams 078a3fd409 Was a little too aggressive with the lossless elab_and_eval
The index expressions ARE self-sized context, we just need to
force the EXPAND flag to make this work.

Stephen Williams 1a3adbe9cd Vec4 store to memories.
This also reworks the working of the %store/vec4 instruction to

Stephen Williams e708a5b59d Handle vec4 part selects / vec4 cassign / repeat statements
These features need to be adapted to the vec4 stack.

Stephen Williams d55e4c0552 Redesign support for system functions that return vec4
Redsign the handling of the return value, including a rework of
the %vpi_func syntax to carry the needed information.

Add a few more arithmetic operator instructions.

Stephen Williams 5ef077fdf6 Start work on converting vec4 expressions to use stack.
Instead of using a bit4 space to hold thread vectors, create a
vec4 stack--much like the real, string, and object stacks--to
hold intermediate values.

Stephen Williams 819770a6c4 Handle enumerations as packed struct/union members.
There were also some subtleties related to using enumerations

bugs related to those issues.

enable or disable assertions.

Cary R 077bd5b7ef Do not return a handle to a port when searching by name
The standard explicitly states that only object with a full name
can be searched for by name. A port does not have a full name and
hence should be skipped so that a different object (the signal,
etc.) can be returned. This patch adds code to skip ports when
searching for an object handle by name.

Cary R 7e55babb62 Fix leaks in the object stack
This patch fixes some leaks in the object stack when getting various

the object stack is clean when a thread is exiting.
