Try to put all the version stamps into common version_base.h
and version_stamp.h header files. All the source programs then
get their version from these header files.
Also handle the version stamps in the man pages by using the
version_*.h header file contents to edit the version strings
in the man page title bar markers.
This patch removes bin32 from the clean targets since it is no
longer user/created. It adds autom4te.cache to the distclean
target in the main directory. It removes the files in driver
that are not created (lexor.c parse.c, etc.). The *.cc.output
files are no longer created so removing them is not needed.
- Add missing dependency of configure on aclocal.m4.
- Remove config stamp files in make distclean (and fix another for
loop in base make distclean that I missed)
- Add stamp files to .gitignore
Use the time stamp file technique recommended by the autoconf manual
to prevent unneccesary rebuilds because of an unchanged config.h.
Uses the automake trick of generating the stamp files in the
_AC_AM_CONFIG_HEADER_HOOK macro instead of littering the source
directory with stamp-h.in files.
Add an extra ./config.status run after ./config.status --recheck
because with --recheck it doesn't actually try to remake the generated
files (and thus doesn't make the timestamp files). Thus without the
extra run, each stamp-*-h target would need to independently run
./config.status to make sure it wasn't changed by the configuration
change.
An orthogonal fix of how config.status is called in subdirectories.
When in a subdirectory and config.status is called with
../config.status and $(srcdir) is a relative path, config.status gets
confused. Fixed by replacing '../config.status --file=Makefile.in'
with 'cd ..; ./config.status --file=<dir>/Makefile.in'
Instead of calling make in subdirectories using a sh for loop, use GNU
make's $(foreach ) to create a string of commands connected with &&.
This way an error in a subdirectory will stop the build, instead of
continuing on to the next subdirectory, which the old version does.
Also added rules to regenerate configure when configure.in changes,
and to run config.status --recheck when that happens.
The newer mkinstalldirs can handle paths that have spaces in them.
While I'm at it, I also updated the Makefiles so that installation
can also work to DESTDIR directories that have spaces.
Rather then spread VERSION= defines throughout all the makefiles, put
the base version in version_base.in. Use that to generate a version.h
that includes the base version as well as the detailed version.
This reverts commit 31d67fcd3e.
The concensus has been that this causes too many build problems in
the general case and what is needed instead is a way to turn on the
extra warnings for developers only.
The code base is almost shadow-free now, so this won't add much noise to the compiles.
Problems I know about:
lxt{,2}_write.c: patch sent upstream
cflexor.c: exposes gray area of name space boundary
This patch cleans up the Makefile.in files.
We only need to delete config.log in the lower directories.
We reference the *.in files at $(srcdir)/
We need to make distclean for the tgt-(fpga,pal,verilog) directories.
This is to cleanup the Makefile.
Add some missing "rm -r f dep"
Collapse all the configure checks to a single configure script in
the root of the source tree. This makes the configure process run
a lot faster, expecially on Windows systems that are slower in general.
This patch fixes the crash in MinGW make distclean. The problem
was that vpi/ and driver-vpi/ were being called twice and the
MinGW make was failing on the second call since the Makefile
was already removed.
Add a dependency on config.h and _pli_types.h in the make all
target. It is likely that only _pli_types.h was needed, but
this makes it clear that they need to be rebuilt if the .in
files change.
The lower directories that depend on the top level config.status
now have a target to rebuild the local Makefile file it the
corresponding Makefile.in changes.
Move the header files from includedir/verilog to .../iverilog
because the verilog name is a little too generic. The iverilog-vpi
command should handle the changes.
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.
acc_ functions. Add support for standard ACC
string handling.
Add the _pli_types.h header file to carry the
IEEE1364-2001 standard PLI type declarations.
