Jean-Paul Chaput 30b92ff33a Add a flag througout all the build system to manage manylinux (PyPI).
* New: In boostrap/FindBootstrap.cmake, add a macro setup_qt() to
    share Python detection across the various tools.
      This macro takes into account the USE_MANYLINUX variable to
    slightly change the Python detection. On a "normal" system we
    look for "Development" (search for dynamic libraries) while under
    manylinux we look for "Development.Module"(static linking).
* Change: In bootstrap/ccb.py, add a new option --manylinux.
* Change: Cleanup in the various CMakeLists.txt to use setup_qt().

Jean-Paul Chaput 10bd5510da Fix library linking problem for gcc 9 and above (Ubuntu 20/Debian 11).
* Bug: In all CMakeLists.txt, it seems I was doing a worng use of
    target_link_library(). No longer add dependencies to the C++ base
    library but instead either to the Python associated module or
    to the final binaries. This was inderectly causing the linking
    problem related to Python (which was a misdirection).
* Bug: Typo in FindLibexecinfo.cmake, do not use FindLib[E]xecinfo.
* Change: In CRL/ccore/CMakeLists.txt, activate SKIP_AUTOMOC on
    bison/flex generated files.
* Bug: In viewer/PyHApplication, do not delete the C++ object in
    the Python destroy method.

Jean-Paul Chaput 02777e127e Migration towards Python3, first stage: still based on C-Macros.
* New: Python/C++ API level:
  * Write a new C++/template wrapper to get rid of boost::python
  * The int & long Python type are now merged. So a C/C++ level,
    it became "PyLong_X" (remove "PyInt_X") and at Python code
    level, it became "int" (remove "long").
* Change: VLSISAPD finally defunct.
  * Configuration is now integrated as a Hurricane component,
    makes use of the new C++/template wrapper.
  * vlsisapd is now defunct. Keep it in the source for now as
    some remaining non essential code may have to be ported in
    the future.
* Note: Python code (copy of the migration howto):
  * New print function syntax print().
  * Changed "dict.has_key(k)" for "k" in dict.
  * Changed "except Exception, e" for "except Exception as e".
  * The division "/" is now the floating point division, even if
    both operand are integers. So 3/2 now gives 1.5 and no longer 1.
    The integer division is now "//" : 1 = 3//2. So have to carefully
    review the code to update. Most of the time we want to use "//".
    We must never change to float for long that, in fact, represents
    DbU (exposed as Python int type).
  * execfile() must be replaced by exec(open("file").read()).
  * iter().__next__() becomes iter(x).__next__().
  * __getslice__() has been removed, integrated to __getitem__().
  * The formating used for str(type(o)) has changed, so In Stratus,
    have to update them ("<class 'MyClass'>" instead of "MyClass").
  * the "types" module no longer supply values for default types
    like str (types.StringType) or list (types.StringType).
    Must use "isinstance()" where they were occuring.
  * Remove the 'L' to indicate "long integer" (like "12L"), now
    all Python integer are long.
* Change in bootstrap:
  * Ported Coriolis builder (ccb) to Python3.
  * Ported Coriolis socInstaller.py to Python3.
  * Note: In PyQt4+Python3, QVariant no longer exists. Use None or
    directly convert using the python syntax: bool(x), int(x), ...
    By default, it is a string (str).
* Note: PyQt4 bindings & Python3 under SL7.
  * In order to compile user's must upgrade to my own rebuild of
    PyQt 4 & 5 bindings 4.19.21-1.el7.soc.
* Bug: In cumulus/plugins.block.htree.HTree.splitNet(), set the root
    buffer of the H-Tree to the original signal (mainly: top clock).
      Strangely, it was only done when working in full chip mode.

Jean-Paul Chaput f1668cec5f Disable BFD support by default.
* Change: In <tool>/CMakeLists.txt, add an USE_LIBBFD option to
    enable the link against the BFD library. Latest versions seems
    to have changed their API.
* Change: In bootstrap/ccp.by & builder/Builder.py, add an option
    "--bfd" (and self._bfd) to enable BFD support.

Jean-Paul Chaput 68e45bc5ab Groudwork for routing density driven placement. Compliance with clang 5.0.1.
This commit contains two set of features that should have been commited
separately.
  1. Compliance with clang 5.0.1, tested with the RedHat collection
     llvm-toolset-7. This allow Coriolis to be compiled under Darwin (MacOS)
     with Xcode & macports. The bootstrap install system has been modificated
     accordingly.
  2. The basic support for routing density driven placement. Related
     features are:
     * Bloat property. Each Occurrence of an Instance can be individually
       bloated. This property not attached to any tool to allow the placer and
       router to share it as wanted. Nevertheless, it is defined in Etesian.
     * BloatProfile in Katana, add individual Bloat properties to Instances
       occurrences based on the East & North overflowed edges of each GCell.
     * Support in ToolEngine for a "pass number" of a tool. This pass number
       is mainly used to make "per pass" measurements. The MeasureSet system
       is improved accordingly to support multiple values of a same measure.
     * Embryo of "P&R Conductor" to perform the place & route loop until the
       design is successfully placed. May be the first brick of a Silicon
       Compiler.

* Change: In boostrap/FindBoostrap.cmake, in setup_boost(), added tag to
    the python component for macport (ex: python27).
* Change: In boostrap/build.conf, put etesian before anabatic for
    instance occurrence BloatProperty dependency.
      Added option support for the "llvm-toolset-7" collection to build
    against clang 5.0.1.
* Bug: In Hurricane::getRecord( const pair<T,U>& ), the getSlot<> templates
    for first & second arguments must be called with <const T> and <const U>
    as the pair itself is const (and not simply <T> & <U>).
* Change: In Hurricane::getSlot() temlate, only use "string" arguments and
    not const string&, simpler for template argument deduction.
* Bug: In Hurricane::AnalogCellExtension, the StandardPrivateProperty<>
    template has a static member "_name". Clang did show that the template
    for this static number has to be put inside the namespace where the
    template *is defined* (i.e. Hurricane) instead of the namespace where
    it is instanciated (i.e. Analog).
* Bug: In Isobar, Matrix_FromListOfList(), PyInt_AsPlacementStatus() must
    be put outside the C linkage back in the Isobar C++ namespace (clang).
* Bug: In Hurricane::DBo::~DBo, and derived add a throw() specification
    (clang).
* Bug: In Hurricane::RegularLayer::getEnclosure() & setEnclosure(), change
    signature so it matches the one of the base class (clang).
* Bug: In Hurricane::CellPrinter, use double brackets for initializer list
    (clang).
* Change: In Hurricane::Breakpoint, reverse the meaning of the error level.
    Only error level *lesser or equal* than the stop level will be enabled.
* Bug: In CRL/python/helpers/__init__.loadUserSettings(), must put the
    current working directory in the sys.path as in certain configuration
    it may not be included.
* Bug: In CRL::ApDriver, DumpSegments(), no longer generate segments when
    encountering a RoutingPad on a top-level Pin Occurrence. The segment
    was generated in the wrong direction, creating DRC violations on the
    "mips_core_flat" example.
* Change: In CRL::Measures, partial re-design of the measurements management.
    Now, each kind of measure can accept multiple values put in a vector.
    The index is intented to match a tool run number.
* Change: In CRL::Histogram, add support for multiple sets of datas,
    indexeds with tool run number.
* Change: In CRL::ToolEngine, add support for multiple pass number, add
    addMeasure<> templates for the various data-types.
* Change: In CRL::gdsDriver & CRL::gdsParser(), comment out unused GDS record
    name constants.
* New: Etesian::BloatProperty, property to attach to Instance occurrences
    that contains the extra number of pitch to add to the cell width.
* Bug: In AutoSegment::CompareByDepthLength, the segment length comparison
    was wrong, it was always returning true, which broke the "strick weak
    ordering" of the comparison.
      This was producing a core-dump in GCell::updateDensity() when sorting
    a vector<>. The end() iterator was being dereferenced, leading to the
    problem.
* Bug: In Katana::DataSymmetric::checkPairing(), the test for segments
    whose axis is perpandicular to the symmetry axis was wrong
    ("!=" instead of "-").
* New: In Katana/GlobalRoute, new ::selectSegments(), selectOverloadedgcells()
    and selectBloatedInstances() to automatically select segments from
    overloaded edges, overloaded GCells and bloated cells.
* Change: In KatanaEngine, return a more detailed success state, distinguish
    between global and detailed.
      Add support for multiple routing iterations.
* New: In cumulus/python/plugins/ConductorPlugin.py, embryo of routing
    driven placement.

Jean-Paul Chaput 435b647ddf Compatiblilty with boost 1.57 on RedHat 6. 2019-03-11 16:01:11 +01:00
Jean-Paul Chaput c76fa034ba Implementation of a red-black tree and an interval tree.
* New: In Hurricane::RbTree, template for red-black tree. Standard
    implementation but well integrated in the Hurricane database and
    ready to be derived (both iterator and Collection support).
* New: In Hurricane::IntervalTree, template for interval tree, derived
    from RbTree.
* New: unittests tool to perform unit tests.
* Change: In Bora::ChannelRouting, now implemented with IntervalTree.
    There is something suspicious here : the "thick" version of
    addWireoccupation() seems never to be called. Have to check the
    wide wire support implementation.
