For constant bit/part selects, issue a warning if the select is out
of range or an undefined value. In any case, the RHS value should be
discarded, and the actual assignment should be skipped.
If a VPI call with real arguments has no calltf function, we still
need to pop the arguments off the vthread stack. Similarly, if it
has a real result, we need to push a value onto the vthread stack.
For constant word indices, issue a warning if the index is out of
range or an undefined value. In any case, the RHS value should be
discarded, and the actual assignment should be skipped.
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.
The changes in COPYING are mostly cosmetic and use <year> vs 19xx, etc.
Also update the tgt-vlog95/Makefile.in copyright to match the formatting
in the FSF version.
If a logical pull device is converted into a CA then it is an assignment
with strength, so just emit the appropriate constant to get the correct
functionality (e.g. 1'b1 for a pull up and 1'b0 for a pull down).
Also add missing file/line information.
There was one section of code in the tgt-vvp back end that was using
deprecated functions. This patch fixes that. The functionality is still
missing (force/assign to part of a vector), but the code now compiles
cleanly (no warnings).
This patch finishes the code needed to translate a SystemVerilog package to a
module with a special name. It also adds code to report that class scopes are
not supported and treats both a class and package as a top level scope.
Rework lexical support for PACKAGE_IDENTIFIER so that the lexor
can help with package scoped identifiers.
Pform package types and package functions up to elaboration.
Add support for case, forever, and repeat statements in constant
functions. Also fix a bug in the constant function implementation
of NetESelect when used for zero/sign extension.
