This patch modifies the iverilog -M command line option to allow
the user to specify an optional output mode that controls which
files get added to the dependency list. This allows the user to
either get a list of all files that contribute to the design,
or a list of the include files, or a list of the module files.
This patch adds two new warning classes that can be enabled or
disabled via the -W command line option. The first controls
whether a warning is generated if a part select within an
always @* statement causes the entire vector to be added to
the implicit sensitivity list. The second controls whether a
warning is generated if a word select within an always @*
statement causes the entire array to be added to the implicit
sensitivity list. The first class is not automatically enabled
by -Wall, the second class is.
This patch adds support for a -Wselect-range warning class to the
driver and ivl programs. This is part of -Wall. The actual checks
will be added in a later patch.
This patch adds -g2001-noconfig command line flag. The compiler
already supported this with `begin_keywords. Document this in
the manual page and fix a few other issues.
Fix endgenerate to be a 2001 keyword and add a few missing
keywords at the appropriate standard level e.g.(unsigned).
Add uwire and deprecate wone. wone used to just convert without
a warning to a wire. uwire will display a warning that it is
being converted to a wire without a check. wone is converted to
a uwire with a warning and then prints the uwire message. The
uwire message will be replaced with a real check fairly soon.
In the past we automatically added the local directory to
the beginning of the include search path. This was found to
conflict with what other tools do so this functionality is
now only available when the -grelative-include option is
given to iverilog.
Functions that appear in continuous assignment expressions and that
have hidden dependencies or side effects need to be re-evaluated
whenever any input to the expression changes. This patch adds support
in the compiler and vvp runtime to enable this. This is currently
activated for any system function call that has no arguments. The
user may also force it to be used for any user function by passing
the option -gstrict-ca-eval to the compiler driver.
This patch also removes the -dautomatic option which was used for
gaining confidence in the code that supports automatic tasks and
functions. It is believed that the testsuite provides reasonable
fault coverage, and further tests can be added if bugs are found.
This patch adds a -V flag to the runtime to print version information.
It also updates the manual page to document this and makes some minor
changes to the iverilog an iverilog-vpi manual pages.
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.
IEEE1364 has specific names for the various generations of Verilog that
are supported. Icarus Verilog should stick to those names for selection
the language feature set.
In the process, the extensions that were tied to the 2x generations
are pulled out out and given their own enable flags. The makes all the
feature control more regular and understandable.
This patch adds check to determine if an always block has delay
in it or not. If there is no delay a runtime infinite loop will
occur. For the indeterminate case it will print a warning message
if the new -Winfloop flag is given. This flag is not part of the
-Wall check!
Add support for a default, standard, implicit include directory
in the base directory for the ivl installation, where standardized
Verilog header files may be placed.
The min/typ/max default warning was not being produced in all
locations a min/typ/max expression could be used. This patch
adds the default warning code to all locations. It also
modifies the manual page to explicitly state that only the
first ten warnings are printed.
This patch adds the ability to call command files from other command
files. There is currently a limit of 16 total levels deep (15 stored
plus the current file). -f is now an alias for -c for both the command
line and command files. The parser also reports errors when they occur
along with the file name and line number to aid in debugging problems.
This patch is rather large and fixes a couple of problems. The major
change is that instead of keeping all the range specifications in
a list that is later processed the information is now kept as
individual entries for the port and net definitions. This allows
easier checking for multiple definitions (pr1660028), more
detailed error messages and the ability to pass the now deprecated
style of a scalar I/O definition used with a vectored net definition.
These changes did require extra code to prevent a single definition
from setting the range values in more than on place.
When using the new ANSI-C style of port declarations (1364-2001 12.3.4
list_of_port_declarations) the compiler ensures that you do not
redeclare the port in the body (it is already completely defined).
This caught a few errors in the test suite (pr859 and sqrt32*).
The flag to disable the normal port checking and allow the deprecated
port syntax is -gno-io-range-error. This will print a warning for the
case of a scalar port with a vectored definition in the body. All
other cases are still considered an error.
