CADP Change List

This page lists the recents changes brought to the CADP toolbox. For more details about particular changes, please refer to the corresponding items in the HISTORY file of the CADP distribution.

Item numbers in red (e.g., "#1758") indicate changes that are not compatible with earlier versions of CADP and may require manual intervention to adapt existing scripts and specifications (see the $CADP/HISTORY file for details). If a red item number is followed by a star (e.g., "#2064*"), this means that the changes can be performed automatically using the "upc" tool provided by CADP (the use of this tool is explained in the $CADP/HISTORY file). As a general rule, we avoid breaking compatibility without good justification.

#1753 Improvement All C functions corresponding to LOTOS operations on natural numbers are now suffixed with "_NAT"
#1754 Improvement LOTOS types IntegerNumber and Integer are no longer identical and now have different signatures
#1755 Improvement Added "div", "mod", and "rem" operations on integers in the predefined LOTOS and LNT libraries
#1756 Improvement Added new tool BCG_CMP providing fast comparison for LTSs and discrete/continuous-time Markov chains
#1757 Improvement Enhanced the "Compare..." menu of the EUCALYPTUS user interface to support the new BCG_CMP tool
#1758 Improvement Option "-class" of BCG_MIN can (and must) now be followed by a filename (or "-" for standard output)
#1759 Improvement Extended the SVL language and compiler to support the new BCG_CMP tool
#1760 Bug fix LNT2LOTOS produced misleading error messages for undeclared gates G used as folows: "G (...) where ..."

2013-11-13 - Change List for CADP Version 2013-k "Zurich"

Acknowledgements are due to the following scientists, who provided valuable feedback taken into account for this version of CADP:

HISTORY file item Type Summary
#1724 Bug fix Option "-iso" of CAESAR did not deactivate the "(*! atomic *)" special comments
#1725 Improvement Changed LNT2LOTOS translator to avoid GCC 4.* warnings ("variable "CAESAR_REGISTER_..." set but not used")
#1726 Bug fix The SVL script of demo_32 contained a tautological comparison ("scenario_S3.bcg" == "scenario_S3.bcg")
#1727 Bug fix The LNT exponentiation operator "**" on real numbers was incorrectly implemented
#1728 Improvement Modified CAESAR and CAESAR.ADT not to emit useless "cascading" type-error messages for undeclared variables
#1729 Improvement CAESAR and CAESAR.ADT emit better error messages for mistyped value expressions in "let" and "ofsort" contexts
#1730 Improvement CAESAR and CAESAR.ADT emit better error messages for non-Boolean guards with a non-declared TRUE operator
#1731 Improvement RFL and INSTALLATOR have been made faster by trying ssh/scp before rsh/rcp
#1732 Improvement New options "-parse" and "-unparse" have been added to GENERATOR to enable/disable BCG label parsing
#1733 Bug fix Type-checking errors for LOTOS equation lists were printed in reverse order by CAESAR and CAESAR.ADT
#1734 Bug fix LNT2LOTOS generated mistyped LOTOS code for patterns containing a constructor of range or predicate type
#1735 Bug fix SVL recovered improperly when the strong minimization of an EXP composition expression failed
#1736 Improvement Entirely revised INSTALLATION_MACOS directives for installing CADP on Mac OS X, adding support for XCode 5.0.1
#1737 Bug fix RFL and TST emitted "expr: syntax error ... [: too many arguments" on Mac OS X
#1738 Improvement Changed the C code generated by CAESAR to avoid a CLANG "-Wparentheses-equality" warning on mac86
#1739 Improvement More explanative error messages for LNT programs containing mistyped gates
#1740 Improvement Modified CADP_CC to remove two CLANG "argument unused" warnings about "-fno-tree-sra" and "-multiply_defined"
#1741 Improvement Changed LNT2LOTOS and its library to avoid GCC 4.2 warnings ("unknown option after '#pragma GCC diagnostic' kind")
#1742 Improvement Added observational equivalence reduction to BCG_MIN and restored ALDEBARAN's "-omin" and "-ocla" options
#1743 Improvement Faster BCG_MIN (linear instead of quadratic complexity in a subroutine) for graphs with a high branching factor
#1744 Bug fix Semantic bug in CAESAR_SOLVE's algorithm A1, causing incorrect results by EVALUATOR 3 and 4 with "-bfs" option
#1745 Improvement Modified CADP_MEMORY to avoid a "dyld: DYLD_ ... is setuid or setgid" warning on Mac OS X 10.8 "Mountain Lion"
#1746 Improvement Ported INSTALLATOR and TST to Mac OS X 10.9 "Mavericks", from which "/usr/bin/gnutar" has been removed
