This configure option causes the installed commands to have
a suffix string that makes them distinct from other versions
that also have a suffix string. This allows for multiple
installed versions of Icarus Verilog.
Also, move installed C/C++ header files into a subdirectory of
their own under the target include directory, to make clearer
the purpose and source of those files.
Get at least basic elaboration of analog processes and contribution
statements. Bring the statements and analog statements together and
net future elaboration work sort out which statements are valid in
a given context. This makes sense because there really is a lot of
syntactic overlap, and analog behavioral code is processed somewhat
sequentially.
Put together the infrastructure for elaborating analog statements,
including create the NetAnalogTop objects that hold analog statements
and are in turn held by the design.
While doing this, clean up the various unique initial/always enumerations
to use the ivl_process_type_t type.
When the -V flag is passed to the iverilog command, we can easily
print the version information for the driver itself, but it is also
valuable to probe all the components that would have been used for
a real compile. So the driver executes the preprocessor and the ivl
core to have them print version information.
The ivl core program also tries to load the target code generator
and get version information to print. For this to work, create a new
optional entry point "target_query" that takes a query key string as
an argument and returns a const string as the result. Use this with
the key "version" to get version information out of the target.
Target selection is done by the DLL target code generator, so there
is no value having a layer of target selection ahead of it. Remove
all that redundant code and simplify the target config files to reflect
this.
My previous patch always used an empty file if git was not
available. This patch extends this to use the existing
version.h file if it exists (snapshot, etc.)
The MinGW system() implementation appears to return the straight
return value instead of the waitpid() like result that more
normal systems return. Because of this just return the system()
result without processing for MinGW compilations.
Older version of the MinGW runtime (pre 3.14) just used the
underlying vsnprintf(). Which has some problems. The 3.14 version
has some nice improvements, but it has a sever bug when processing
"%*.*f", -1, -1, <some_real_value>. Because of this we need to use
the underlying version without the enhancements for now.
snprintf prints %p differently than the other printf routines
so use _snprintf to get consistent results.
Only build the PDF files if both man and ps2pdf exist.
MinGW does not know about the z modifier for %d, %u, etc.
Add some missing Makefile check targets.
The tran devices include tran, rtran, tranif0/1 and rtranif0/1. These
are all elaborated as options on a NetTran device. It is still not
clear the best way to present tran devices via the ivl_target.h API.
Parse discipline declarations, net discipline declarations, and
analog contribution statements. Don't yet do anything useful with
these, just give a sorry message where they are encountered.
This is part of the standard disciplines header file, with enough
syntax to part the natures and disciplines included. Don't do anything
with the parse results yet.
Package builders/managers find the DESTDIR variable convenient for
installing into a temporary target for building a package. This adds
the DESTDIR varilable to the root makefile.
Also, clean up the verilog.spec file to reduce redundancy so that
maintence for releases is easier.
The va_math.vpi module implements systen-function versions of the
Verilog-A math functions. This library was contributed by Cary R.
Also add the constants.vams include file. This is pretty much
direct from the Verilog-AMS LRM.
commonly, the make install is run in a compiled directory by a
different user (i.e. an administrator) that doesn't necessarily
have write access to the build directory. This patch fixes it so
that the test that the version.h is up to date doesn't need to
write a temporary file in the build directory.
It also makes sure that if there is a real need to update the
verion.h, and it is not writable, then properly fail the build.
A patch to insert the version string from git broke compilation when
the source was not a git repository or when building in a read-only
source tree. This patch avoids breaking compilation by using a
graceful failure mechanism for generating the version string and does
not write to the source tree.
Modules, functions and tasks are named scopes so derive them all
from the PScope base class. These items all take scoped items, so
the eventual plan is to move these items into PScope.
