Anabatic transient commit 18. Port of Kite (Katana), Yeah, Baby! Yeah!
* Bug: In Hurricane, in StaticObservable::getObserver(), if the slot
pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Clean parameters for routing topologies. Improved 2RL- support.
Previously, the relevant NetBuilder and routing strategies where
directly guessed from the RoutingGauge traits. This is no longer
doable as the combinations increases. Now to configure both the
global and detailed router we need three "parameters" :
1. The routing gauge itself (tells which layers are in which
directions) and how to make the VIAs.
2. The NetBuilder to use, they are identified by strings.
Currently we support:
* "HV,3RL+", for all SxLib derived standard cells.
* "VH,2RL", for hybrid routing (over the cell, but terminals
are also in the first RL).
* "2RL-", for strict channel routing.
* "VH,3RL+", an attempt for FreePDK 45, not optimized enough
to be considered as usable.
3. The routing style, mostly affect the way the GCell grid will be
built.
* VH : first RL is V.
* HV : first RL is H.
* OTH : Run in full over-the-cell mode (needs at least 3RL).
* Channel : Run in *strict* channel routing mode (no routing over
the standard cells).
* Hybrid : Create channels, but can use H tracks over the
standard cells.
Thoses three parameters are partly overlapping and must be sets in
a consistent manner, otherwise strange results may occurs.
* New: CRL::RoutingGauge::getFirstRoutingGauge(), to get the lowest
layer available for routing (not a PinOnly, not a PowerSupply).
* Change: In CRL::RoutingGauge::isHV() and isVH(), were previously
always returning false when the gauge was 2RL only. Now, check
on the first usable RL.
* Bug: In cumulus/plugins.block.configuration._loadRoutingGauge(),
there was a bad computation of the deep RLs when the top layer
was not defined. Occured for 2RL gauges only.
* Bug: In Anabatic::RpsInRow::slacken() (LayerAssign), forgotten curly braces
in the test to skip METAL2 terminals.
* Change: In Etestian::BloatChannel::getDx(), adjust the bloating
policy to converge on Arlet6502. Always ensure that there is
a 50% ratio between terminal used V-tracks and free ones.
If there is more than 80% of terminals, add one more track.
* Bug: In AnabaticEngine & KatanaEngine, KatanaEngine is a derived
class of AnabaticEngine. They uses Anabatic::Configuration
and Katana::Configuration that also derives from each other.
I though I had made one configuration attribute in the base
class that was using the right Configuration. But no. I did
have two configurations attributes, one in AnabaticEngine and
one in KatanaEngine, the later "shadowing" the former. As a
results, parameters modified in AnabaticEngine, *after* the
initial creation of the tool *where never seen* at Katana
level (due to it's own duplicate). What a mess.
Now there is only one attribute in the *base* class Anabatic,
which is created through a new virtual function _createConfiguration()
called in _postCreate() which allocate the right Configuration
according to the dynamic type of the tool (KatanaEngine).
In KatanaEngine, access the configuration through the
attribute (_configuration) and not the accessor (getConfiguration()).
* Bug: In KatanaEngine, no longer directly use the _configuration attribute
(which is not accessible anyway) but the getConfiguration() accessor.
The accessor perform a static_cast from the Super::getConfiguration()
into Katana::Configuration.
Complete cleanup of the various configuration accessors.
* New: AnabaticEngine::setupNetBuilder(), perform an early check
of the requested NetBuilderStyle. The NetBuilderStyle is just a
string that will be matched against the (hard-coded) supported
NetBuilders. Then check the topological characteristics against
the capabilities of the gauge (HV, VH and so on).
Still a bit too hard-coded for now.
This function has been split from AnabaticEngine::_loadGrByNet().
* Change: AnabaticEngine::isChannelStyle() renamed from isChannelMode().
* New: In Anabatic::Configuration, two new attributes to select the
topology and routing style:
- _netBuilderStyle to explicitely select the NetBuilder to use.
It's a string, which is provided by each NetBuilder.
- _routingStyle to define how the overall routing will work.
It's a set of flags (StyleFlags):
* VH : first RL is V.
* HV : first RL is H.
* OTH : Run in full over-the-cell mode (needs at least 3RL).
* Channel : Run in *strict* channel routing mode (no routing over
the standard cells).
* Hybrid : Create channels, but can use H tracks over the
standard cells.
* New: In anabatic/Constants, add StyleFlags to define how the router
should operate (see above).
* Bug: In Anabatic::GCell, in CTOR, no reason to set up the HChannelGCell flag.
* Bug: In Anabatic::GCell::updateDensity(), when computing layers non contiguous
saturation, do not systematically skip RL 0, but only if it's PinOnly.
* Change: In Anabatic::NetBuilder, rename isTwoMetal by isStrictChannel.
* Change: In Anabatic::NetBuilderHV, rename doRp_AccessNorthPin() in
doRp_AccessNorthSouthPin(). More accurate.
* Bug: In NetBuilderHV::_do_1G_xM1_1PinM2(), the wires to connect the M1
terminals where created *twice*. Uterly stupid, there where placed in
overlap by the router!
* New: In AnabaticEngine, new accessors to the NetBuilderStyle and
RoutingStyle, proxies towards Configuration.
* Bug: In Manipulator::relax(), if there are two doglegs to be done, but
they are in the same GCell, only do one (the conflicting interval)
is short.
* Change: In Katana::Session, rename isChannelMode() into isChannelStyle().
* Change: In TrackSegment::isUnbreakable() and isStrap(), return false
when the base segment is a *weak global* (aligned with a global one).
* Change: In Katana::Row::createChannel(), correctly distinguish between
*strict channel* style and *hybrid* style. Tag the GCells as std cells
row or channels only in the former case.

pointer is NULL, do not try to access the owner. Returns NULL, so
the caller can be aware of the situation...
* Change: In Hurricane, in BreakpointWidget & ExceptionWidget some
cosmetic changes (fonts and window sizes).
* Bug: In Anabatic, In AutoHorizontal::getConstraints(), take into account
the constraints from the source AutoContact, as it holds the constraints
transmitted by the RoutingPads and sets up by propageConstraintsFromRp().
It is likely to be a bug affecting the original Katabatic as well.
* Change: In Anabatic, in RawGCellsUnder(), check that the segment is not
completly oustside the cell abutment box and truncate the coordinates
to the part that is inside. Use the "shrink" if we reach the east/north
border.
* Change: In Anabatic, in Configuration, no more decorator because we will
use a true derived relationship. Katana *derives* from *Anabatic* and do
not *decorate* it, so the Configuration can do the same. It also implies
that we directly create a Katana engine, not an Anabatic one.
* Change: In Anabatic, in Session, do not allow the opening of the Session
in a standalone fashion (with a static method). Instead it must be opened
using the relevant method of the Anabatic/Katana engine. This ensure we
are opening the right Session type.
* Change: In Anabatic, in AutoSegment_Aligneds() collection the seed segment
is not part of the collection by default, but will be included if the
Flags::WithSelf is set.
* Change: In Configuration, all the flags value are now defined in two steps.
Declared in the header and initialized in the module. This is to prevent
the fact that on some cases, in relation with the Python "extern C" part
modules, we need a true allocated variable. It was causing weird linking
problems.
A side effect is that they can no longer be used as entry is switches,
have to replace them by if/else.
* New: In Anabatic, new GCell::getNeighborAt() utility function.
* Bug: In Anabatic, in GCell::doGrid(), tag all the GCells of the grid with
the grid type... Back annote all the edges capacity (north & east) with
the reserved local capacity.
* New: Complete portage of Kite over Anabatic. The new engine is christened
"Katana" for Kite-Analogic. When it's capabilities and performances
will be on a part with Kite, it is to completly replace it (and take
back the "Kite" name). Preliminary tests seems to show that, contrary
to intuition (because built on a more complex/slower grid), it is even
slightly faster than Kite 8-).

Update the channel routing feature to integrate with the OTC P&R.
* Update: In CRL/node600/phenitec/kite.py, update the routing gauge to
the new format. So now we can use again SxLib-2M (channel routing
SxLib for two metal technologies).
* Change: In CRL::BlifParser, if a master cell is not found in the
AllianceFramework, then try in the Blif supplied libraries.
This is used to load the zero, one and tie cells.
Add a Blif::getCell() static function to look into the Blif
supplied libraries.
* Change: In CRL::LefImport, sometimes there can be discrepencies between
the LEF ROUTING layers and the Coriolis routing gauge. Now ignore
routing layers that are *not* presents in the Coriolis gauge.
* Change: In AnabaticEngine, moved routingMode attribute from KatanaEngine,
as some setup operations needs it.
* Change: In AutoSegment::canReduce(), allow fixed segments to be reduced
if they are "jumpers" (turn+turn and top+top or bot+bot).
This case arise on the edge of routing channels for fixed wires
to connect terminals.
* Change: In AutoSegment::getTopologicalinfos(), compute differently the
(leftBound,rightBound) interval when in channel mode.
In over-the-cell mode, this interval is the one of the whole
GCells under the wire. In channel mode, for fixed wires (that is,
verticals connecteds to cells) this interval is reduced to half
the GCell height, on the connected side of said channel.
This allows Manipulator::_insertToTrack() to issue disantangling
requests (push left/push right) for fixed segments that are face
to face in the channel.
* Change: In Anabatic::Configuration CTOR, allow the cellGauge to have a
different name from the routingGauge. Now if the cell gauge that
should match the routing gauge is not found, fallback to the
name set in "anabatic.cellGauge" parameter.
Case occur when we try to match with CORE sites from LEF files.
* Change: In Etesian::Configuration CTOR, same change as in the
Anabatic configuration.
* Change: In Anabatic::GCell::updateDensity(), never set the GoStraight
flag in channel mode. This flag makes sense when there is at least
4 routing layers (so we have 2 contiguous free of blockages).
* Bug: In Anabatic::Session::_getNearestGridpoint(), sometimes the nearest on
grid point is outside the constraint box. Now force the point
to remains inside constraints even if offgrid.
* Change: In Katana::DataNegociate::update(), perpandiculars that are
either reduced or in non-preferred routing direction should not
trigger a bug message.
* Change: In KatanaEngine::_check(), do not check for fixed, horizontal
non-prefs AutoSegments in channel mode (avoid false bug display).
* Bug: In Manipulator::_forceToTrack(), slighty shrink (-1) the interval
to free. The intersection function of intervals returns true when
the two intervals *exactly* touches (1.vMax == 2.vMin). But in
this specific case, they are not *overlapping* and no action
should be taken...
* Bug: In Manipulator::_insertInTrack(), do not reject the track when
we are overlapping a fixed vertical segment in channel mode.
(Hmm, maybe already corrected by the previous one).
* Change: In Katana::NegociateOverlapCost(), in channel mode, do
not put two overlaping vertical fixed segments into infinite cost.
This happens when two cell connected verticals are face to face in
a channel. We want them negociated the track (by shrinking their
length) instead of excluding it right away.
* Change: In NegociateWindow::createTrackSegment(), in channel mode,
do not attempt to create a track segment over a fixed and reduced
AutoSegment.
Do not attempt to put a non-preferred AutoSegment on a Track
either.
* Bug: In RoutingEvent::revalidate(), the number of availables tracks
was badly computed when in the pure constraint case, when there
was only one it was reporting zero.
* Change: In TrackElements::TrackElements_Perpandicular::Locator,
do not issue a bug when an non-pref or reduced AutoSegment do not
have an associated TrackElement.
* Change: In TrackSegmentCost::update(), do not issue a bug when a
perpandicular is reduded or non-pref and do not have a TrackElement.

Clean parameters for routing topologies. Improved 2RL- support.
Previously, the relevant NetBuilder and routing strategies where
directly guessed from the RoutingGauge traits. This is no longer
doable as the combinations increases. Now to configure both the
global and detailed router we need three "parameters" :
1. The routing gauge itself (tells which layers are in which
directions) and how to make the VIAs.
2. The NetBuilder to use, they are identified by strings.
Currently we support:
* "HV,3RL+", for all SxLib derived standard cells.
* "VH,2RL", for hybrid routing (over the cell, but terminals
are also in the first RL).
* "2RL-", for strict channel routing.
* "VH,3RL+", an attempt for FreePDK 45, not optimized enough
to be considered as usable.
3. The routing style, mostly affect the way the GCell grid will be
built.
* VH : first RL is V.
* HV : first RL is H.
* OTH : Run in full over-the-cell mode (needs at least 3RL).
* Channel : Run in *strict* channel routing mode (no routing over
the standard cells).
* Hybrid : Create channels, but can use H tracks over the
standard cells.
Thoses three parameters are partly overlapping and must be sets in
a consistent manner, otherwise strange results may occurs.
* New: CRL::RoutingGauge::getFirstRoutingGauge(), to get the lowest
layer available for routing (not a PinOnly, not a PowerSupply).
* Change: In CRL::RoutingGauge::isHV() and isVH(), were previously
always returning false when the gauge was 2RL only. Now, check
on the first usable RL.
* Bug: In cumulus/plugins.block.configuration._loadRoutingGauge(),
there was a bad computation of the deep RLs when the top layer
was not defined. Occured for 2RL gauges only.
* Bug: In Anabatic::RpsInRow::slacken() (LayerAssign), forgotten curly braces
in the test to skip METAL2 terminals.
* Change: In Etestian::BloatChannel::getDx(), adjust the bloating
policy to converge on Arlet6502. Always ensure that there is
a 50% ratio between terminal used V-tracks and free ones.
If there is more than 80% of terminals, add one more track.
* Bug: In AnabaticEngine & KatanaEngine, KatanaEngine is a derived
class of AnabaticEngine. They uses Anabatic::Configuration
and Katana::Configuration that also derives from each other.
I though I had made one configuration attribute in the base
class that was using the right Configuration. But no. I did
have two configurations attributes, one in AnabaticEngine and
one in KatanaEngine, the later "shadowing" the former. As a
results, parameters modified in AnabaticEngine, *after* the
initial creation of the tool *where never seen* at Katana
level (due to it's own duplicate). What a mess.
Now there is only one attribute in the *base* class Anabatic,
which is created through a new virtual function _createConfiguration()
called in _postCreate() which allocate the right Configuration
according to the dynamic type of the tool (KatanaEngine).
In KatanaEngine, access the configuration through the
attribute (_configuration) and not the accessor (getConfiguration()).
* Bug: In KatanaEngine, no longer directly use the _configuration attribute
(which is not accessible anyway) but the getConfiguration() accessor.
The accessor perform a static_cast from the Super::getConfiguration()
into Katana::Configuration.
Complete cleanup of the various configuration accessors.
* New: AnabaticEngine::setupNetBuilder(), perform an early check
of the requested NetBuilderStyle. The NetBuilderStyle is just a
string that will be matched against the (hard-coded) supported
NetBuilders. Then check the topological characteristics against
the capabilities of the gauge (HV, VH and so on).
Still a bit too hard-coded for now.
This function has been split from AnabaticEngine::_loadGrByNet().
* Change: AnabaticEngine::isChannelStyle() renamed from isChannelMode().
* New: In Anabatic::Configuration, two new attributes to select the
topology and routing style:
- _netBuilderStyle to explicitely select the NetBuilder to use.
It's a string, which is provided by each NetBuilder.
- _routingStyle to define how the overall routing will work.
It's a set of flags (StyleFlags):
* VH : first RL is V.
* HV : first RL is H.
* OTH : Run in full over-the-cell mode (needs at least 3RL).
* Channel : Run in *strict* channel routing mode (no routing over
the standard cells).
* Hybrid : Create channels, but can use H tracks over the
standard cells.
* New: In anabatic/Constants, add StyleFlags to define how the router
should operate (see above).
* Bug: In Anabatic::GCell, in CTOR, no reason to set up the HChannelGCell flag.
* Bug: In Anabatic::GCell::updateDensity(), when computing layers non contiguous
saturation, do not systematically skip RL 0, but only if it's PinOnly.
* Change: In Anabatic::NetBuilder, rename isTwoMetal by isStrictChannel.
* Change: In Anabatic::NetBuilderHV, rename doRp_AccessNorthPin() in
doRp_AccessNorthSouthPin(). More accurate.
* Bug: In NetBuilderHV::_do_1G_xM1_1PinM2(), the wires to connect the M1
terminals where created *twice*. Uterly stupid, there where placed in
overlap by the router!
* New: In AnabaticEngine, new accessors to the NetBuilderStyle and
RoutingStyle, proxies towards Configuration.
* Bug: In Manipulator::relax(), if there are two doglegs to be done, but
they are in the same GCell, only do one (the conflicting interval)
is short.
* Change: In Katana::Session, rename isChannelMode() into isChannelStyle().
* Change: In TrackSegment::isUnbreakable() and isStrap(), return false
when the base segment is a *weak global* (aligned with a global one).
* Change: In Katana::Row::createChannel(), correctly distinguish between
*strict channel* style and *hybrid* style. Tag the GCells as std cells
row or channels only in the former case.

Replace "unsigned int" by "Flags" in all AutoSegments collections.
* Change: In Anabatic::AutoSegments collections, change the type of all
the flags that where in "unsigned int" (32 bits) to Flags (uint64_t)
as there is now more than 32 flags for functions.
* New: In Ababatic::Constants, added new flag Flags::WithPerpands, which
makes the number of flags tip over 32 bits, thus making mandatory
to uses Flags and not unsigned int.
* New: In Anabatic::AutoSegments_Perpandiculars, manage a new flag
Flags::WithDoglegs to allow to propagate through global segments that
are connecteds via doglegs on local segments. Meaning that there is
a good chance that they could be aligned.
Slighly change the way we propagate on aligned segments: no longer
check for VTee or HTee, but only for same direction and layer as
master.
* New: In Anabatic & Katana, replace all the "int", "long" and their
variants by the less implementation ambiguous "int32_t", "int64_t"
(and variant). This should help to better detect bit trucation in
flags.
Use the type to give a hint about the flags kind:
- Type "Flags", for flags shared among Anabatic & Katana
functions/methods (may also appear in some objects states).
- Type "uint32_t" for flags belonging to an object internal
state of from Hurricane functions flags (those should be
grouped in a Flag subclass in a perfect world).
