Stephen Williams ec6009dd8f Compile out the T<...> format in vvp.
This ifdef's the code out. Leave it in place for a little longer
for reference.

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 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.

Stephen Williams 819770a6c4 Handle enumerations as packed struct/union members.
There were also some subtleties related to using enumerations
from typedefs and using them in multiple places. Fix various
bugs related to those issues.

Stephen Williams 7669a42cfb Handle some assertion syntax in the parser.
Implement some yacc rules for assertion syntax.

Add the -gassertions/-gno-assertions command-line flags to
enable or disable assertions.

Stephen Williams 0d6c15e45a Handle packed unions properly during elaboration.
This also gets r-value use of packed unions correct.

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.

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.

Cary R f47af361cd For default function arguments do not access an out of range real argument.
The code should only look at the real argument that exist any missing
arguments default to not being defined and hence needs to use the
default expression. Found with valgrind.

Stephen Williams 68d83383ff Elaborate nested l-values.
This gets nested l-values to (but just short of) the ivl_target API.
Now the elaborator can process nested l-values, but I haven't figured
out how to present that at the ivl_target.h API.

Stephen Williams 9bd9c8f301 Implement class extends arguments.
This implements constructor arguments right after the base class
name in the class extends syntax.

Stephen Williams f16fd03dab Elaborate PChainConstructor calls.
It is better to leave the handling of PChainConstructor calls to
the elaboration, instead of stripping them out early. This allows
for handling the arguments of the chain constructor in the correct
scope.

Stephen Williams a7d8c983ba Blend initializer statements into any explicit constructor.
If there is an explicit constructor, then blend all the statements
of the implicit constructor into it so that there is only one
constructor function.
