When running `make check` on a UNIX-like operating system
with the specified `configure` option, `vvp` was unable to
find the required shared library.
This commit ensures that the runtime linker can locate the library.
This fixes issue #1313.
The clang dlltool is not compatible with the binutils dlltool. However
both the clang and binutils linkers support reading the .def file and
creating the import library directly, so we no longer need to perform
the link in two stages.
We need to build libvvp with a suffix from the outset to ensure that
the vvp binary searches for the correct library file name once it is
installed.
Also Windows DLLs need to be stored in the same directory as the main
program, not in a separate lib directory.
Commit 95810b2f61 mistakenly added the suffix to the output file name
when linking the final vvp.exe binary. 'make check' and 'make install'
assume the suffix is only added when installing.
With a pattern rule, the recipe will only be executed once, even when
the rule has multiple targets. Using this to handle the output from
bison is included as an example in the GNU make manual.
This fixes the makefiles so that bison-generated header files will be
regenerated if they are deleted.
The current bison (3.7) generates a *.cc file that includes the header
it generated. For parse.cc this would be parse.hh. Right now, we rename
this header to have a common name used in other files, but this results
in a compile error for the parse.cc file:
parse.cc:462:10: fatal error: parse.hh: No such file or directory
462 | #include "parse.hh"
| ^~~~~~~~~~
Fix this by telling bison to output the header file to the correct
filename in the first place so that we don't have to rename it.
(using the --defines instead of -d option).
This looks like a bison specific option not available in Posix yacc;
but looks like we're requiring bison anyway.

In PR #300, @xdch47 pointed out a stable way to fix parallel
installation problems.
This fix applied the method, thanks!

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.
bison 3.4.1 writes the header file before the c++ file. Our makefile
rules make the header files depend on the c++ files, so we need to
fix the timestamps accordingly.
Note we only want these enabled when building the compiler and runtime
binaries. If we included the ICARUS_VPI_CONST definition in the global
CPP_FLAGS, that would propagate to the flags used by iverilog-vpi, so
would affect compilation of user VPI code.
When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.
Before this patch, WARNING_FLAGS applied to both C and C++,
and WARNING_FLAGS_CXX applied to C++ only.
This patch adds a WARNING_FLAGS_CC that applies to C only.
That change should be generally useful; in particular the C
code is almost ready for -Wstrict-prototypes, which does not
apply to C++.
-Wextra (or -W) used to only apply to C++ via WARNING_FLAGS_CXX.
This patch moves it to WARNING_FLAGS, to apply to both C and C++.
Unfortunately, that triggers a ton of warnings.
For now, cover most of the new warnings up by adding
-Wno-unused -Wno-sign-compare -Wno-type-limits
to WARNING_FLAGS_CC. In the long run, I want to change the C coding
style, and take off these disable-warning flags. But those changes
can dribble in as separate commits; this patch is big enough already.
Actually fix a couple missing-field-initializers in libveriuser/veriusertfs.c.
This provides the ivl_target.h interface for class definitions
and expressions, the vvp code generator support for class objects
and properties, and the vvp run time support. Trivial class objects
now seem to work.
Create stub class objects at the vvp level and generate the code
to invoke that stub. Implement the routines needed to implement
a test for null object references.
