Stephen Williams f1855eed0e Fix system function call in net types to get proper vector width.
This means using some of the new vec4 infrastructure to get at the
data, instead of using the old thread bit pointers. In the process,
remove the vbit and vwid members that pointed to thread bits. Those
bits no longer exist.

Stephen Williams aee540d8bb Fix sort of %event command in vvp compile list.
The sort is important, the names must be sorted because the table is
searched using binary search.

Stephen Williams 1a3adbe9cd Vec4 store to memories.
This also reworks the working of the %store/vec4 instruction to
take a part offset, and eliminate the %store/vec4/off instruction.

Stephen Williams f89dbd48c8 Add vec4 support for bitwise or/nor/nand/xor/xnor. 2014-01-04 23:48:16 +00:00
Stephen Williams 9fc3e84e93 vec4 cassign to part selects. 2014-01-04 22:58:58 +00:00
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 54926840e6 Handle vec4 stack version of concatenation. 2013-12-28 07:50:37 +02:00
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.

Cary R 92e4ca3a92 Report that vpi_handle_by_index() is not supported for a vpiNet 2013-12-12 17:10:26 -08:00
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
class properties. With this fix an assert can be added to verify that
the object stack is clean when a thread is exiting.

Cary R ae90da9951 Improve the classs cleanup code when using valgrind 2013-12-03 09:16:24 -08:00
Stephen Williams fa8d35ae9c Support nested l-value objects
This allows for syntax like a.b.c where a is a class with member
b, which is a class with member c, and so on. The handling is mostly
for the support of compound objects like classes.

Cary R 04bab6b197 Fix a problem with reaping a thread with detached children
When a thread that has detached children is reaped the detached children
need to be fully detached so they can be reaped correctly. If they are not
fully detached then they may reference a parent that has already been
reaped (memory freed). Found with valgrind.

Martin Whitaker 1814c24a90 Fix pullup/pulldown behaviour for tri1/tri0 nets.
Currently vvp only applies the pullup/pulldown for tri1/tri0 nets when
the net is not driven. The correct behaviour is to treat the pullup/
pulldown as an extra driver (with pull strength).

Martin Whitaker a024efb615 Add -compatible command line option to vvp.
This option is intended to make it easier to compare results from
Icarus with results from other simulators. For now, the only effect
it has is to change the default format for displaying real numbers
when no format string is supplied.

Stephen Williams e60804cf41 Handle initialized darray of strings
This includes adding support for returning strings from functions,
adding initializing new darray with array_pattern strings, and
assigning an array_pattern of strings to a preallocated darray.
Also fix up support for initializing array with simple string
expression.
