* | * generic/tclCompExpr.c: Call TclCompileSyntaxError() whendgp2007-08-271-23/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | struct (again "free" due to alignment requirements) to mark those subexpressions that are completely known at compile time. Enhanced CompileExprTree() and its callers to precompute these constant subexpressions at compile time. This resolves the issue raised in [Bug 1564517].

| | | | | | | | | | | | | | | | OpNode mark field scheme of tree traversal. This eliminates the need to use magic values in the left and right fields for that purpose. Also stop abusing the left field within ParseExpr() to store the number of arguments in a parsed function call. CompileExprTree() now determines that for itself at compile time.
* | * tests/parseExpr.test: Update source file name of expr parser code.dgp2007-08-061-262/+285
| | | | | | | | | | | | | | | | | | * generic/tclCompExpr.c: Added a "mark" field to the OpNode struct, which is used to guide tree traversal. This field costs nothing since alignement requirements used the memory already. Rewrote ConvertTreeToTokens() to use the new field, which permitted consolidation of utility routines CopyTokens() and GenerateTokensForLiteral().

| | | | | | | | | | | | | | | | | | | | | | ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an end goal of filling a Tcl_Parse with Tcl_Tokens representing the parsed expression, or TclCompileExpr() with the goal of compiling and executing the expression. In the latter case, more aggressive conversion of QUOTED and BRACED lexeme to literals is done. In the former case, all such conversion is avoided, since Tcl_Token production would revert it anyway. This enables simplifications to the GenerateTokensForLiteral() routine as well.
