Vec4 store to memories.
...
This also reworks the working of the %store/vec4 instruction to

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.

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.
2013-12-03 17:24:42 -08:00
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.

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.
2013-11-20 18:01:35 -08:00
4047ed7976
Add support for SV wait fork to the run time.
2013-10-22 16:00:29 -07:00
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.

51ca2d1243
Fix using array elements in expressions with an array element lval.
...
When you have an expression like this (extreme example):
a[idx[1]][idx[2]*4 +: 4] <= #(idx[3]) 4'ha;
where a is a reg array and idx is a reg or net array. The retrieval
of idx[2] was clobbering index register 3, which was set before
evaluating the part offset expression, then used in the %set/av of the
array value. (likewise for idx[1] and idx[3]])
To avoid this issue, this patch adds and uses a new instruction
%ix/mov which simply copies one indexed register to another. When
necessary, expressions are first evaluated into temporary registers to
avoid clobbering, then moved in to place before the %*/av instruction.

Automatic scope are OK in detached threads
...
...assuming certain conditions that should by definition be
true. So this patch amounts to improving an assert condition.

Fix subtle issues related to fork/join of tasks.
...
When a fork/join contains a task, the task completion may become
confused with the completion of another thread if any of the
threads are embedded in the main thread. So always create threads
for all the fork paths, and joins to match.
2013-08-29 20:31:26 -07:00

Expand the scope of the parent variable.

34f6e25b4e
Revised fix for bug 931.
...
We can't directly determine that a %fork operation is a task or function
call, so need to infer this by comparing the parent and child scopes.

Update a few comments for changes to thread fork/join behaviour.

cbaf36d4b8
Fix for br931.
...
Task and function calls are handled in vvp using the fork/join
instructions. The join instruction after a call must reap the
task/function thread.
2013-05-27 09:34:44 +01:00
0aca19356c
Added thread stack memory leak check to vvp.
...
When a vvp thread terminates, its real and string stacks should be empty.
Adding assertions to this effect catches some code generator bugs.
