Hi, I am currently meddling with the design of a large and quite powerful parser restructure. The problem is that it definitely calls for use of the YYBACKUP macro (I am trying to explore using a different sort of lexical tie-in, but that seems more complex).
The problem is that YYBACKUP simply is broken (see the TODO in Bison sources). It is broken in 2.4.1 (the version I have installed), and apparently it is still broken in master. I have submitted a fix to the bison bug list, but obviously even if it is applied, it will take years to percolate down to general availability. Would it be acceptable to let autoconf check for that bug and activate the fix in the form of a redefinition in parser.yy when needed? -- David Kastrup _______________________________________________ lilypond-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-devel
