When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.
This generates an EQZ LPM device that carries the case-z-ness to
the code generator.
Also add to the vvp code generator support for the EQZ device so
that the synthesis results can be simulated.
Account for the wildcard devices in the sizer.
This allows for syntax like a.b.c where a is a class with member
b, which is a class with member c, and so on. The handling is mostly
for the support of compound objects like classes.
Emit the elaborated class methods. Also generate root scopes to
represent the classes in order to hold the methods. These scopes
can also in the future be used to implement static properties.
This provides the ivl_target.h interface for class definitions
and expressions, the vvp code generator support for class objects
and properties, and the vvp run time support. Trivial class objects
now seem to work.
Add properties to the classes, and elaborate expressions that
have class properties. Describe class object property references
all the way down to the stub target.
Added: basic vpiPort VPI Objects for vpiModulkes
vpiDirection, vpiPortIndex, vpiName, vpiSize attributes
Since ports do not exist as net-like entities (nets either side
module instance boundaries are in effect connect directly in
the language front-ends internal representation) the port information
is effectively just meta-data passed through t-dll interface and
output as a additional annotation of module scopes in vvp.
Added: vpiLocalParam attribute for vpiParameter VPI objects
Added: support build for 32-bit target on 64-bit host (--with-m32
option to configure.in and minor tweaks to Makefiles and systemc-vpi).
This patch fixes a few more bugs in the enumeration code.
It add support for saving the file and line information to make
diagnostic messages better.
It updates some of the compiler warning messages to use the file
and line information.
It passes if the enumeration type is signed all the way to the
code generators.
It fixes the parser to correctly have the range after the signed
designation for the vector types.
It adds a warning that vvp does not currently support a negative
two state enumeration value.
The vvp target code generator may not elide a BUFZ if the output of
the BUFZ is connected to a net that is the subject of a procedural
force statement.
This patch adds code to the compiler so that a constant string
in a structural context can maintain the string property. This
is needed but not currently implemented in vvp (it's still
converted to a number). A pending patch for the vlog95 target
does use this new information.
Fixes regression of simple_gen test.
Also extended ivl_lpm_size API call to support all LPM types. This
simplifies some of the VHDL LPM generation code a little.
This patch adds code that allows the targets to determine if a logical
gate came from a continuous assignment. This helps some of the targets
generate code that more closely matches the input.
It also reworks/simplifies the synthesis of && and || since the
compiler has already converted the two operands to single bit form
and fixes a mismatched delete from a previous patch.
This patch adds some preliminary module port information to the ivl
interface. This may change as I investigate exactly what is needed.
It also fixes a few minor bugs (a missed local variable and spacing)
This patch modifies the compiler and the ivl interface to pass the
type of indexed part select that is being represented (up/down) in
a procedural L-value or R-value. This is needed by any back end that
wants to correctly denormalize the (zero based) base expression.
This patch adds support to the compiler/ivl interface for getting the
original UDP definition port names. ivl_udp_port() was added to get
this information.
This patch fixes a bunch of objects to have the correct file/line
information. It also adds support for getting file/line information
for events (named events have a definition line).
