This patch is a slight modification to files Tony Bybell (the author of
GTKWave) send to me. We still have a few more changes we plan to make,
but this should be functional enough for initial testing. Multi-treading
and speed/size flags will be added shortly.
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.
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.
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 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.
This patch adds the constant system functions for Verilog-2005
and Verilog-AMS. These are evaluated at compile time. $abs(),
$min() and $max() support their polymorphic behavior in the
compiler where it really matters. They are always evaluated
as reals in the run time and the result/argument(s) will be
converted as needed.
The Verilog-2005 functions are available if using the 2005
generation (default) and if either the icarus-misc (also on
by default) or verilog-ams flags are set.
The Verilog-AMS functions are available if either the
icarus-misc or verilog-ams flags are set.
This patch adds the $clog2 system function. It also makes this
function work as a constant function. The runtime version still
needs to be updated to use an integer based version instead of
the current double based method. The double method suffers from
rounding errors.
This patch adds $simparam and $simparam$str from Verilog-A.
The analog simulator parameters return 0.0 or N/A. The
vvp_cpu_wordsize system function has been moved into the
$simparam call and is now named CPUWordSize.
This patch also starts the factoring of common code in the
vpi directory. Some routines were renamed.
The priv.c file was renamed to sys_priv.c to match the
include file.
System functions can now have strings put to their output.
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.
This patch adds a new system function $vvp_cpu_wordsize. It returns
the size of the underlying CPU word (long) in bits. This function
can be used to write fully portable tests for the test suite. Other
functions will be added as needed.
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.
