mjoekhan 7fe2ddda0b VVP: array-pattern object values for class queue properties
Support IVL_EX_ARRAY_PATTERN in object evaluation for queue-typed class properties: build an empty queue and append pattern elements, matching darray array-pattern object handling. Fix vec4 stack use so %queue/append_word/v is not double-popped. Update class queue locator regression to use direct c.q = '{...} assignment.

mjoekhan c189cc2642 SystemVerilog: honor with-clause for class queue min/max
Route class queue-property min/max calls with `with (...)` through predicate-based locator elaboration so filtered extrema behave consistently with queue and darray locator semantics.

mjoekhan 0cd7205585 SystemVerilog: support locator methods on class queue properties

mjoekhan 7cac25cbd1 SystemVerilog: add unique()/unique_index() with predicates

mjoekhan 789bff4861 VVP: support array-pattern objects in dynamic-array property assignment
Handle IVL_EX_ARRAY_PATTERN in object evaluation by constructing a dynamic-array object and filling elements, so direct class property assignments like c.d = '{...}; codegen correctly without requiring a temporary variable.

mjoekhan 8f18edd20d SystemVerilog: class darray property locator methods and VVP prop fixes
Add class dynamic-array property support for locator methods (find*, unique*, min/max, with predicates) by elaborating dynamic-array property method calls to queue-method sfuns. Extend VVP property paths to treat property values as queue-or-darray sources, not queue-only, and fix object-stack handling in property locator loops so temporary accumulator objects do not hide the class object.

Add regression coverage for class dynamic-array property locators and update locator-method test documentation/listing.

mjoekhan 3ccba27edb SystemVerilog: darray unique methods and min/max with(predicate)
Add dynamic-array unique() and unique_index() support and extend queue/darray min() and max() to accept locator with(...) predicates. Generate dedicated _with sfuns for min/max, emit VVP code for filtered scans, and reduce through new object-stack min/max opcodes.

Cover the new behavior with ivtest regressions for darray unique and queue/darray min/max with predicates, and update locator method documentation.

mjoekhan 30b4afa7d2 SystemVerilog: add min/max locator methods for queue and darray
Implement queue and dynamic-array min()/max() for integral vec4 element types, with VVP support for both queue-backed and darray-backed storage and regressions in ivtest. Keep min/max as no-arg methods and document current behavior alongside existing locator tests.

mjoekhan 20bd360aec SystemVerilog: queue/darray locator methods (find*, unique*) and VVP darray support
Implement array locator methods for SystemVerilog queues and dynamic arrays:
find, find_index, find_first, find_first_index, find_last, find_last_index,
unique, and unique_index. Support both value arguments (equality) and
with (predicate) forms using implicit item and index in the iterator scope.

Elaboration returns queue-typed results for first/last/index locators per LRM
(empty queue when no match). Fix assignment compatibility between queues and
dynamic arrays where element types match.

VVP: extend %queue/size, %queue/word, %queue/find*, and %queue/unique* paths
so nets holding vvp_darray (including atom-backed int[]) are handled, not
only vvp_queue_vec4. Queue types still subclass vvp_darray; resolve vec4
queues before plain dynamic arrays. Fall back to the legacy get_queue_object
path for non-vec4 queues. Document opcode and source file touchpoints in
ivtest/ivltests/README_sv_queue_locators.txt.

Add vvp regressions: sv_queue_find*, sv_queue_unique, sv_queue_find_locators_ext,
sv_darray_find_locators.

mjoekhan 24c1293801 Add SystemVerilog chained calls a().b() and regression
Implement call_chain_expr in the parser, PECallFunction chain prefixes,
elaboration for class methods on returned handles, and prefix class resolution
for width checks on multi-hop chains. Place call_chain_expr before bare
hierarchy_identifier in expr_primary so id ( is not reduced as a lone ident.

Document behavior and developer notes in devel/sv_call_chain.md (including
that iverilog uses the installed lib/ivl/ivl binary).

Add ivtest sv_call_chain_method1 normal test with -g2012.

Dag Lem ba7da9d5a5 Guard against overflow / wrap around of internal part-select bit address
Internally, the maximum address space of a vector is 31 bits + a sign bit
to signal invalid addresses (out of bounds or has one or more x or z bits).

This commit ensures that unsigned part-select bit addresses which would
otherwise overflow and wrap around within this address space are correctly
handled as out of bounds.
