5.1:
- improvements to GC 2 generations generic speedups - new scheme for attvars - hProlog like interface also supported - SWI compatibility layer - extra predicates - global variables - moved to Prolog module - CLP(R) by Leslie De Koninck, Tom Schrijvers, Cristian Holzbaur, Bart Demoen and Jan Wielemacker - load_files/2 from 5.0.1 - WIN32 missing include files (untested) - -L trouble (my thanks to Takeyuchi Shiramoto-san)! - debugging of backtrable user-C preds would core dump. - redeclaring a C-predicate as Prolog core dumps. - badly protected YapInterface.h. - break/0 was failing at exit. - YAP_cut_fail and YAP_cut_succeed were different from manual. - tracing through data-bases could core dump. - cut could break on very large computations. - first pass at BigNum issues (reported by Roberto). - debugger could get go awol after fail port. - weird message on wrong debugger option. git-svn-id: https://yap.svn.sf.net/svnroot/yap/trunk@1402 b08c6af1-5177-4d33-ba66-4b1c6b8b522a
