This is syntax permitted in 1364-2001 but removed in 1364-2005.
Also update the iverilog man page to document the anachronisms warning
class that warns about use of this feature when a later generation is
selected.
The compiler was emitting a "sorry" message and aborting compilation when
it encountered attributes on a wire declaration/assignment. Change this
to a warning, as most attributes are ignored anyway.
"# include <string>" was added so "Microsoft Visual Studio Express 2015 RC Web" could compile it without error. "static void operator delete[](void*); was preprocessed so "Microsoft Visual Studio Express 2015 RC Web" could link it without error for a function not yet implemented.
"child->delay_delete = 1;" was added, for when building with "Microsoft Visual Studio Express 2015 RC Web" in DEBUG mode, so that pr2909555.v would pass with -strict, otherwise it would cause memory access error will trying to access the previously deleted "child" variable.
First and second areas were changed for "Microsoft Visual Studio Express 2015 RC Web" so that gold files would match. For the third area of change, "Microsoft Visual Studio Express 2015 RC Web" wanted to print 6 zeros after the decimals for the values of 0.0 and -0.0, and then the gold files wouldn't match.
Changes so "Microsoft Visual Studio Express 2015 RC Web" could build it without a bunch of runtime errors and crashes during regression testing. When declaring an bitfield variable of type enum in a struct, the enum has to have an underlying integer type for MSVC++ when compiling a C++ file, and for these cases, it had to be unsigned integer for everything to work okay during regression testing.

First area of Change for "Microsoft Visual Studio Express 2015 RC Web" was for compiling with error when NDEBUG defined. The second and third areas of change for "Microsoft Visual Studio Express 2015 RC Web", the dynamic_cast has to come first so parpkg_test.v, parpkg_test1.v, parpkg_test2.v would pass.
Changes for "Microsoft Visual Studio Express 2015 RC Web" to first check for a dereferencable iterator so pr1741212.v, and many others, will pass with a DEBUG build.
Implicit ports may be unnamed, either because the port expression
is not a simple/escaped identifier, or because there is no port
expression. To handle these cases, error messages should report
the port position as well as the port name.
In the special case that a net is attached to an island port, values
driven onto the net via the VPI must go to the functor, not the filter,
so that they propagate through the island.
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.
vvp_net_t::force_vec4 propagates all bits of the forced value passed
to it, regardless of the mask value. I can't see any way to fix this
directly, so instead make sure anything that calls force_vec4 sets
the unforced bits of the passed value to the correct value.
Conditions to detect rising/falling edges were incorrect.
VHDL standard specifies it has to detect the current value,
rather than compare against the previous one.
