Use the precompiled defines file support of the ivlpp preprocessor
to pass defines made in the main program to processed library modules.
In other words, a `define in the Verilog source will be visible to
library modules.
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.
Prevent an overflow of command line flags if the -Wall argument
is used multiple times, and fix processing of individual flags
that may be in the beginning of the warnings flag buffer.
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.
