Fix malloc/free and new/delete problems, plus some initializations.
...
This patch fixes some allocation problems (mostly in the parser
and lexor relating to identifiers). It also fixes a couple places
where uninitialized variables were used. All found with valgrind.
There are still 100 tests that have problems. Many of these appear
to be related.

Fix lexical scopes within case-generate alternatives.
...
Case-generate alternatives create sub-scopes that need to be scanned
by the scope scanner in order to get function definitions etc. that
are defined lexically within generated scopes.

Rework handling of lexical scope
...
Move the storage of wires (signals) out of the Module class into
the PScope base class, and instead of putting the PWires all into
the Module object, distribute them into the various lexical scopes
(derived from PScope) so that the wire names do not need to carry
scope information.
This required some rewiring of elaboration of signals, and rewriting
of lexical scope handling.

Objects of lexical scope use PScope base class.
...

Factor compile-time scopes into PScope class
...
Modules, functions and tasks are named scopes so derive them all
from the PScope base class. These items all take scoped items, so
the eventual plan is to move these items into PScope.

Add support for generate case
...
Generate case is a complex generate scheme where the items are
sub-schemes of the case generate itself. The parser handles them
something like nested generate statements, but storing the case
guards as the test expression. Then the elaborator notes the
case scheme and reaches into the case item schemes inside to make
up tests, select the generate item, and elaborate.

LineInfo uses perm_string for path.

Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

Do not use the error token to get file/line number information.

to alleviate this problem.

Print out a warning if extra digits are given for sized binary, octal

decimal constants are not checked.

This patch adds min_typ_max to expressions. Remember when using a

Relax the requirement on list of port declarations for implicit ports.
...
Previously list of port declarations were considered a complete
definition of the port. This caused problems for some, so this patch
allows implicitly defined ports (no wire/reg/etc.) to have net
declarations in the body.
2007-08-29 18:38:36 -07:00
b69c4c9a2c
Fix range handling/checking and add a flag to allow deprecated port syntax.
...
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.
