| | | | | | | | | | | | | | * generic/tclCompCmds.c: simplify code that might need to grow * generic/tclCompExpr.c: an array of Tcl_Tokens in the parsePtr * generic/tclParse.c: field of a Tcl_Parse. Replaces the TclExpandTokenArray() routine via replacing: int needed = parsePtr->numTokens + growth; while (needed > parsePtr->tokensAvailable) { TclExpandTokenArray(parsePtr); } with: TclGrowParseTokenArray(parsePtr, growth); This revision merged over from dgp-refactor branch.

* Generalize the ensemble compiler further. Still doesn't precopile rewrites, ↵dkf2007-11-211-50/+138

* Greatly improved ensemble compiler. This one now can handle any ensemble.dkf2007-11-161-68/+287

| | | | | | | | | | | | | | | | expression syntax errors are found when compiling expressions. With this in place, convert TclCompileExpr to return void, since there's no longer any need to report TCL_ERROR. * generic/tclCompile.c: Update callers. * generic/tclExecute.c: * generic/tclCompCmds.c: New routine TclCompileSyntaxError() * generic/tclCompile.h: to directly compile bytecodes that report a * generic/tclCompile.c: syntax error, rather than (ab)use a call to TclCompileReturnCmd. Also, undo the most recent commit that papered over some issues with that (ab)use. New routine produces a new opcode INST_SYNTAX, which is a minor variation of INST_RETURN_IMM. Also a bit of constification.

TclStackFree now takes a (void *) argument which is the pointer intended to be freed. TclStackFree will panic if that's not actually the memory the call will free.
