Fold in Windows VPI routing for vpip_format_pretty, fix queue method
argument elaboration via elaborate_rval_expr, reject class tasks used as
expressions cleanly, and update br1005 now that class queues compile.
Review follow-up: move vpip_format_pretty to vpip_format.cc with
diagnostic return strings, restore NetNet-based queue method elaboration
with a separate property path, drop spurious /devel/ from .gitignore,
and bump copyright years on touched files.
Formatting pass per inline review: brace style for multi-line if bodies,
||/&& at end-of-line continuations, switch/case indentation, single-line
if returns, NetNet-based sys_task_method_ again, and aligned extern decls.
This adds a "-q" option on the vvp command line and a vvp_set_quiet_flag()
function in the VVP library API. Setting this flag will cause all output
to standard output via MCD bit 0 to be suppressed. It will not prevent the
output being sent to a log file if the vvp "-l" option has been used, and
it will not affect output to the STDOUT file descriptor.
The code assumed all handles stored in vpip_root_table were modules. This
is true for traditional Verilog, but not so for SystemVerilog.
Whilst here, also add support for iterating over packages.
__CYGWIN32__ is not defined when building with the 64-bit Cygwin
toolchain. According to the Cygwin FAQ, __CYGWIN__ has been defined
since 1998, so this should still work for users on 32-bit systems.
The old scheme of linking the VPI modules with the vvp exports meant they
did not work when loaded by the compiler. Instead, let each client create
a jump table for the VPI routines and pass that to each VPI module as it
is loaded.
In vvp, the __vpiSignal object holds a pointer to the scope containing
the signal. This was getting set to the current scope when the net was
finally resolved, rather than to the scope where the net was declared.
The .scope needs to be aware of return types so that the %call/vec4
function knows how to intialize the return value. We also need to
extend the %ret/vec4 to support writing parts of the return value.
When putting a value onto a wire, the value needs to be sent to the
filter, not the functor (the functor may be part of the expression
that drives the wire).
Force and release weren't implemented properly (or at all in the
case of real values). They need to behave the same as the force
and release operations in vthread.cc.
