Have you given any consideration to a variable sized yystack? Parser memory used might be less in typical cases considering sizeof(yyStackEntry)*100 = 2000 bytes on x86. The yyParser struct would need a few new members (malloc function pointer, free function pointer, stack capacity). The API for ParseAlloc() would need an additional argument for a free function to resize yystack on demand in yy_shift() - but ParseFree() could then lose its free function argument since it would already be in the yyParser struct. SQLite may not need such a deep stack, but I can see other Lemon generated parsers benefitting from this. > on parsing some deeply right-recursive SQL statements (and apparently > you are) then you will need to increase the depth of the stack. > If you use the version of Lemon that I just checked in to build > the parser, then you do this by compiling the parse.c file using > > -DYYSTACKDEPTH=10000 ____________________________________________________________________________________ We won't tell.
