The new option allows parameter, net and events to be used before
declaration. With variants
-gno-strict-net-declaration for nets and events,
-gno-strict-parameter-declaration for parameters.
With `-ggno-strict-parameter-declaration` a warning is issued for
parameter use before declaration. This warning suppressed with
the new class `-Wno-declaration-after-use`, instead of `-Wno-anachronisms`.
The standards requires that parameters must be declared
before they are used. Using -gno-strict-parameter-declaration
will allow using a parameter before declaration, e.g., in a port
declaration, with the parameter declared in the body of the
module. Prior to version 13 this was allowed, so there is a large body
of existing code depending on the pre version 13 behaviour.
A common use case (prior to the introduction of localparam) was to
use macros to define constant values, and to put global constant
values in an include file that gets included by each source file.
This will generate a lot of spurious warnings if we warn about all
redefinitions. Make this new option the default for -Wall.
This adds a -u option to the driver to allow the user to specify that
they want each source file to be treated as a separate compilation
unit, and modifies the compiler to accept a list of files (either on
the command line or via a file specified by a new -F option). This
list of files is then preprocessed and parsed separately, causing all
compiler directives (including macro definitions) to only apply to the
file containing them, as required by the SystemVerilog standard.
Return and print an error if iverilog is unable to open dependencies
file. User can pass e.g path to existing directory in '-M' option,
which makes fopen to return NULL followed by crash in fclose.
This was already supported in command files, using the '-v' flag.
'-v' is already in use on the command line, so use '-l' instead,
and make that an alias for '-v' in command files.
Pull request #116 added the ability for the iverilog driver to determine
ivl_root from the location of the iverilog executable (this is needed to
support relocation at the time iverilog is installed). However, the code
did not support the possible variations in the library path name.
The -W option does not (currently) support comma separated lists and
silently ignores any string that doesn't match a known warning class.
Fix by outputing a warning message when the -W argument is unknown.
