* * generic/tclExecute.c: changed the check for overflow in sums,Miguel Sofer2007-08-191-18/+12
| | | | | | | | | | | reducing objsize, number of branches and cache misses (according to cachegrind). Non-overflow for s=a+b: previous ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0)) now (((a^s) >= 0) || ((a^b) < 0)) This expresses: "a and s have the same sign or else a and b have different sign".
* * generic/tclVar.c: improved localVarNameType caching to leverageMiguel Sofer2007-08-171-9/+42
| | | | | the new availability of Tcl_Obj in variable names, avoiding string comparisons to verify that the cached value is usable.
* * generic/tclExecute.c: check the two most frequent instructionsMiguel Sofer2007-08-161-1/+17
| | | | before the switch. Reduces both runtime and obj size a tiny bit.
* * generic/tclCompExpr.c: Added a "constant" field to the OpNodedgp2007-08-161-90/+296
| | | | | | | | 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].

* * generic/tclCompExpr.c: Revise CompileExprTree() to use thedgp2007-08-101-65/+117
| | | | | | | | 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().

| | | | | | | | | | * generic/tclExecute.c (TEBC, TclGetSrcInfoForCmd): * generic/tclInt.h: * generic/tclTrace.c (TclCheck(Interp|Execution)Traces): Removed the need for TEBC to inspect the command before calling TEOvI, leveraging the TIP 282 infrastructure. Moved the generation of a correct nul-terminated command string away from the trace code, back into TEOvI/GetCommandSource.
* * generic/tclParse.c: In contexts where interp and parsePtr->interpdgp2007-07-191-20/+20
| | | | | | might be different, be sure to use the latter for error reporting. Also pulled the interp argument back out of ParseTokens() since we already had a parsePtr->interp to work with.

| | | | | | | | * generic/tclCompCmds.c (TclCompileWhileCmd): * generic/tclCompile.c (TclCompileScript): Corrected faulty avoidance of INST_START_CMD when the first opcode in a script is within a loop (as produced by 'while 1'), so that the corresponding command is properly counted [Bug 1752146].
* * generic/tclCompExpr.c: Added a "parseOnly" flag argument todgp2007-07-111-49/+29
| | | | | | | | | | | 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.

* * generic/tclCompExpr.c: Added a field for operator precedencedgp2007-07-101-40/+165

Also, converted precedence definitions and lookup tables to use symbolic constants instead of raw number for improved readability, and continued extending/improving/correcting comments.
