Stephen Williams 9964d67e5e Implicit crop of vectors assigned to vector properties.
The %store/prop/v takes a width so that it is guaranteed that
all assignments to a vector property will get the size right.

Stephen Williams 98799ff7fa Allow class properties to be arrayed.
This adds the runtime support for class properties that are classes
to be arrayed. Add a means to define the dimensions of a property
in the vvp format, and add functions for setting/extracting elements
of a property.

Stephen Williams dec4cd5071 Handle arrays of class objects.
This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.

Cary R 0a6d75f1db Fix some cppcheck warnings (format string vs argument mismatches) 2014-08-01 18:55:44 -07:00
Stephen Williams f8dc430fe5 Add synthesis support for casez statements.
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.

Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.

Account for the wildcard devices in the sizer.

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 e5eb754150 vec4 versions of a bunch of unary operators. 2014-01-05 14:12:27 -08:00
Stephen Williams 063c6d6065 Add the %event instruction, remove %ix/get and %ix/get/s. 2014-01-05 12:39:52 -08:00
Stephen Williams 2fc8ce8a16 Implement vec4 basec %assign delay and event / vpiTimeVal for functions. 2014-01-05 12:04:16 -08:00
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.
2014-01-05 10:30:59 -08:00
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.

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 4047ed7976 Add support for SV wait fork to the run time. 2013-10-22 16:00:29 -07:00
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.

Stephen Williams 82ebf6372c Generate code to implement new element initializers. 2013-10-19 15:34:15 -07:00
Cary R aa9a7435dd Start of support for %disable/fork opcode. 2013-10-17 15:10:58 -07:00
Jared Casper 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.

Stephen Williams c49b21115a Handle strings as class object properties.
While we are at it, fix a handling of null strings in
string expressions.
2013-01-27 20:10:25 -08:00
Stephen Williams 106850ca7d Handle real value class properties.
As a side effect, this also adds support for 64bit integers.
2013-01-27 20:10:25 -08:00
Stephen Williams 074055bc58 Implement static arrays of strings.
This means extending the vvp to add .array/str objects and
include instructions to access the array. Also add the parser
and code generator support.
