In ivl_alloc.h we redefine malloc(), realloc() and calloc() to have
standard error checking. We don't want to do this for anything that
comes from the standard headers. This specifically doesn't work if
a C++ header files does std::malloc, etc.
Also change to -W instead of -Wextra since that is more portable. I
plan to add a check from -Wextra and use it when available since it
is more descriptive.
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.
Follow-up to "Brainless start to const-correct changes"
Still actually does nothing, but now if the #define ICARUS_VPI_CONST
in vpi_user.h is changed to const, Icarus is almost const-correct,
as checked with gcc flags -Wcast-qual -Wwrite-strings.
Choosing when to #define ICARUS_VPI_CONST const is left as an
exercise for the reader.
With these two patches applied, and the const define, there are
still about a dozen const problems left.
The functions (malloc, free, etc.) that used to be provided in
malloc.h are now provided in cstdlib for C++ files and stdlib.h for
C files. Since we require a C99 compliant compiler it makes sense
that malloc.h is no longer needed.
This patch also modifies all the C++ files to use the <c...>
version of the standard C header files (e.g. <cstdlib> vs
<stdlib.h>). Some of the files used the C++ version and others did
not. There are still a few other header changes that could be done,
but this takes care of much of it.
gcc on OpenBSD reported shadow warnings for variables, arguments named
log, time and exp. This patch renanes those variables to logic, timerec
and expr.
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.
The Cygwin compiler is a bit picky. This patch adds some casts
to remove compilation warnings. In the past I have had warnings
off because of problems with the STL, but for C directories
like this it makes sense to enable the warnings. It also does
not recognize that an assert(0) or assert(false) ends a routine
so it complains about no return at end of function or variables
not being defined.
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)
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'
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.
This patch cleans up the V-2005 and V-analog math functions to
free their allocated memory at the end of simulation. It also
modifies the veriusertfs code to do the same thing.
It also closes the VCD file at EOS.
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.
Remove the #ident and $Log$ strings from all the header files and
almost all of the C/C++ source files. I think it is better to get
this done all at once, then to wait for each of the files to be
touched and edited in unrelated patches.
This patch removes the CVS ident information from the Makefile.in
files it also puts in the current version 0.9.devel for the default
VERSION definition. This is normally passed down, but a local make
will use the value from the local Makefile. This will eventually be
replaced with a file based version to give us just one place to
reliably modify the version.
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.
Nothing to do with tab width! Eliminates useless
trailing spaces and tabs, and nearly all <space><tab>
pairings. No change to derived files (e.g., .vvp),
non-master files (e.g., lxt2_write.c) or the new tgt-vhdl
directory.
Low priority, simple entropy reduction. Please apply
unless it deletes some steganographic content you want
to keep.
The code to handle real functions using the PLI 1 interface was
missing some functionality. This patch fixes that and fixes a
bug in the veriuser.h include file.
