In vvp, create the .var/str variable for representing strings, and
handle strings in the $display system task.
Add to vvp threads the concept of a stack of strings. This is going to
be how complex objects are to me handled in the future: forth-like
operation stacks. Also add the first two instructions to minimally get
strings to work.
In the parser, handle the variable declaration and make it available
to the ivl_target.h code generator. The vvp code generator can use this
information to generate the code for new vvp support.
Added: basic vpiPort VPI Objects for vpiModulkes
vpiDirection, vpiPortIndex, vpiName, vpiSize attributes
Since ports do not exist as net-like entities (nets either side
module instance boundaries are in effect connect directly in
the language front-ends internal representation) the port information
is effectively just meta-data passed through t-dll interface and
output as a additional annotation of module scopes in vvp.
Added: vpiLocalParam attribute for vpiParameter VPI objects
Added: support build for 32-bit target on 64-bit host (--with-m32
option to configure.in and minor tweaks to Makefiles and systemc-vpi).
Class methods belong in a class scope, not the containing module.
So create a lexical scope that carries tasks and functions and
create a PClass to represent classes.
Not all the lex/yacc (flex/bison) targets were using a consistent syntax.
This patch fixes that and explicitly serializes the *.c/*.cc and *.h build.
Not doing this was causing problem when using make -j. The issue appears to
be that if two targets are specified for a rule (e.g. file.cc file.h: file.y)
make does not realize they are both built by the same call so the rule is
executed twice. Once for the .cc target and once for the .h target. This is
not a problem for a serial build. To work around this only use the .c/.cc
file in the main target and then make the .h file depend on the .c/.cc file
as a sub-target.
The --always flag to git describe is harmless in the normal case,
and helpful in some special cases. Also add the --dirty flag to
get extra interesting details.
Added an explicit option prefix="yy" to files that were generated
without an explicit -P.
This makes the lex-generated symbol names self contained without any
help from from build system.
This patch fixes the ivl build to find files in libmisc using vpath instead
of a separate target. The existing constructs caused build problems after
running a make clean. It also adds an empty checking target to vhdlpp.
Include the compiler infrastructure to vhdlpp for collecting the
file and line information and attaching it to entities and ports.
Make the parser store the file name during parse.
Create a libmisc library where I can put source files that are
used by multiple programs within the source tree.
This patch doesn't completely fix the problem, but with it the problem
is at least manageable. The issues was that when the lexor_keyword.gperf
file is updated and you are building outside the source directory the
Makefile would create a local lexor_keyword.cc as expected. The problem
is that it always looked in the source directory for the file. This
patch adds a special vpath rule that says to look in the build directory
first and then in the source directory for lexor_keyword.cc.
This works as expected except for the first time the lexor_keyword.cc
file is generated locally. During the make invocation it compares the
source lexor_keyword.cc file to the gperf file and notices it is out of
date. It then generates a new file in the build directory, but the make
rule is still using the source file which didn't change so it doesn't
rebuild as needed. To get the new file to compile you need to run make
a second time to get the rule to execute using the local version of the
file. This extra make invocation is only needed when the local file is
first created since after that the rule always uses the local file.
I plan to look at resolving the remaining issue, but there is much
subtlety in this since you effectively need to break/rebuild the make
dependency tree to get this to build correctly in a single run.
This patch covers more than it should. It removes many of the -Wextra
warnings in the main ivl directory. It also makes some minor code
improvements, adds support for constant logicals in eval_tree (&&/||),
adds support for correctly sign extending === and !==, it starts to
standardize the eval_tree debug messages and fixes a strength bug
in the target interface (found with -Wextra). The rest of the warnings
and eval_tree() rework will need to come as a second patch.
The files we get from GTKWave are not under our control so we need to
ignore the cppcheck style warnings for them. The random routines are
from the standard so they should not be changed to fix style warnings
either. We also have some weird, but correct pointer subtraction that
cppcheck warns about. This patch adds suppression files for all these
warnings. You must have the latest cppcheck from git since I submitted
a patch that adds the ability to place comments in the suppression file.
This patch changes all the iterator code to use a prefix ++ instead
of postfix since it is more efficient (no need for a temporary). It
is likely that the compiler could optimize this away, but lets make
it efficient from the start.
This patch adds support for running cppcheck from the Makefile. It also
standardizes the order of some of the targets. It renames vpip_format.c
to vpip_format.cc and fixes the size of the array tables to make room
for the trailing NULL. Found when using a C++ compiler.
Create the .var/2u and .var/2s variable records and give them
basic implementations. Make available to VPI the proper types
for the SystemVerilog types that these variables represent.
This patch updates all the Makefile.in files and configure.in
as follows:
Do not use the -Wall warning flag when using the SunPro compiler.
The SunPro compiler uses -xMD instead of -MD.
There are still more fixes needed before Icarus will compile
on OpenSolaris.
This is the initial commit in an effort to build a 1364-1995
back end for Icarus Verilog. It is expected that this back end
will allow the user to write 1364-2005 RTL and then using this
back end (converter) generate functionally equivalent 1364-1995
compatible code. This can be used to support older tools in a
work flow. The primary focus will be simulation equivalence,
though I expect to verify logical equivalence as well.
Like I did for SystemVerilog the other day this patch adds all the
Verilog-AMS 2.3.1 keywords. This necessitated adding one my byte
to the gperf -k argument (byte 9) to make the laplace_?? tokens
have a unique hash.
dlltool which is used by both MinGW and Cygwin to create dynamic
libraries must have the name of the executable it creates the
library/information from exactly match the installed executable
name. If we have a suffix then it must be used. This patch adds
that to the build process for vvp since it can be installed with
a suffix. It also modifies the check routines since you must run
vvp with a suffix if the library it links to was built for a
suffixed executable.
We do have one C program in the vvp directory so add CFLAGS to
the Makefile. This patch also modifies the two local programs
tables and version to use -Wall.
These explicit dependencies are not normally needed (because they
are covered by automatic dependency generation) but when the "-jN"
flag is passed to gmake, they help gmake schedule parallel builds.
(cherry picked from commit 5479aaf721)
Add driver-vpi to either SUBDIRS or NOTUSED depending on if we
are building for MinGW or not. This is more logical and allows
the clean and distclean targets to be simplified.
This patch fixes a few more issues related to building
in a remote directory. The start of the problem was
that the version file was not getting built correctly.
This necessitated using vpath instead of VPATH to only
allow the %.cc files. After that a few other places
needed to have $(srcdir) added.
The distclean target was also enhance so that when
building from a remote directory (srcdir != .) we
remove all the extra files and directories.
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.
