* Made Tcl_UniCharNcmp faster on big-endian machines; the system memcmp()isdkf2002-05-291-2/+2
| | | | | probably optimized far in excess of anything we could do! Little-endian just use the old code...
* * generic/tclInt.decls:hobbs2002-05-291-32/+59
| | | | | | | | | | | | | | | | | | | | | | | * generic/tclIntDecls.h: * generic/tclStubInit.c: * generic/tclUtf.c: added TclpUtfNcmp2 private command that mirrors Tcl_UtfNcmp, but takes n in bytes, not utf-8 chars. This provides a faster alternative for comparing utf strings internally. (Tcl_UniCharNcmp, Tcl_UniCharNcasecmp): removed the explicit end of string check as it wasn't correct for the function (by doc and logic). * generic/tclCmdMZ.c (Tcl_StringObjCmd): reworked the string equal comparison code to use TclpUtfNcmp2 as well as short-circuit for equal objects or unequal length strings in the equal case. Removed the use of goto and streamlined the other parts. * generic/tclExecute.c (TclExecuteByteCode): added check for object equality in the comparison instructions. Added short-circuit for != length strings in INST_EQ, INST_NEQ and INST_STR_CMP. Reworked INST_STR_CMP to use TclpUtfNcmp2 where appropriate, and only use Tcl_UniCharNcmp when at least one of the objects is a Unicode obj with no utf bytes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | command initialization. * generic/tclCompCmds.c: added new compile commands for append, lappend, lindex and llength. Refactored set and incr compile commands to use new TclPushVarName function for handling the varname component during compilation (also used by append and lappend). Changed string compile command to compile toplevel code as well (when possible). * generic/tclCompile.c: added new instruction enums * generic/tclCompile.h: added debug info for new instructions * generic/tclExecute.c (TclExecuteByteCode): moved elemPtr to toplevel var (oft-used). Added definitions for new bytecode instructions INST_LIST_INDEX, INST_LIST_LENGTH, INST_APPEND_SCALAR1, INST_APPEND_SCALAR4, INST_APPEND_ARRAY1, INST_APPEND_ARRAY4, INST_APPEND_ARRAY_STK, INST_APPEND_STK, INST_LAPPEND_SCALAR1, INST_LAPPEND_SCALAR4, INST_LAPPEND_ARRAY1, INST_LAPPEND_ARRAY4, INST_LAPPEND_ARRAY_STK, INST_LAPPEND_STK. Refactored repititious code for reuse with INST_LOAD_STK (same as INST_LOAD_SCALAR_STK), INST_STORE_STK (same as INST_STORE_SCALAR_STK). Updated INST_STR_CMP with style of fix of 2001-04-06 Fellows [Bug #219201] as that fix only affected the runtime eval'ed "string" (string compare is normally byte-compiled now). We may want to back these out for speed in the future, noting the problems with \x00 comparisons in the docs. * generic/tclInt.h: declarations for new compile commands. * generic/tclVar.c: change TclGetIndexedScalar, TclGetElementOfIndexedArray, TclSetElementOfIndexedArray and TclSetIndexedScalar to use flags. The Set functions now support TCL_APPEND_ELEMENT and TCL_LIST_ELEMENT as well. * generic/tclInt.decls: * generic/tclIntDecls.h: minor signature changes for above.

| | | | | | | | | | * generic/tclExecute.c: * tests/expr-old.test: Re-wrote Tcl's [expr rand()] and [expr srand($seed)] implementations, fixing a range error on some 64-bit platforms. Added tests that detect the bug. The rewrite changes the seed -> sequence map on 64-bit platforms, only for seed >= 2^31, a slight incompatibility. [Bug 121072, Patch 102781]
* * docs/scan.n:hobbs2000-12-101-10/+12
| | | | | | | * tests/scan.test: * generic/tclScan.c (Tcl_ScanObjCmd): changed %o and %x to use strtoul instead of strtol to correctly preserve scan<>format conversion of large integers. [Patch #102663, Bug #124600]

Added INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH bytecode ops. Extended evalstats output info with Tcl_IsShared stat info.
* * generic/tclInt.h: Added function prototypes forericm2000-05-231-1/+20
| | | | | | | | | | | | | | | | | | | | | | TclCompileStringCmd and TclCompileReturnCmd. * generic/tclCompile.h: Added definition of INST_STRLEN opcode and updated LAST_INST_OPCODE value. * generic/tclBasic.c: Added information about TclCompileStringCmd and TclCompileReturnCmd to BuiltInCmds table. * generic/tclExecute.c (TclExecuteByteCode): Added support for the INST_STRLEN opcode. * generic/tclCompCmds.c (TclCompileStringCmd): Basic implementation of byte-compiled [string] command. Not all subcommands are implemented; those that are not an out-line compiled. (TclCompileReturnCmd): Byte-compiled implementation of [return] command. Only "simple" returns are byte-compiled; in particular, if the -code, -errorinfo or -errorcode flags are used, the command is not byte-compiled.

| | | | | | | | | | | | * tests/expr.test: * tests/expr-old.test: added tests for 'eq' and 'ne' * generic/tclExecute.c: * generic/tclCompile.h: added INST_STREQ and INST_STRNEQ opcodes that do strict string comparisons. * generic/tclCompExpr.c: added 'eq' and 'ne' string comparison operators. * generic/tclParseExpr.c (GetLexeme): added 'eq' and 'ne' expr parse terms (string (in)equality check).
* * tests/namespace.test:hobbs2000-03-271-22/+31
| | | | | | | | | * generic/tclNamesp.c (Tcl_Export): added a uniq'ing test to the export list so only one instance of each export pattern would exist in the list. * generic/tclExecute.c (TclExecuteByteCode): optimized case for the empty string in ==/!= comparisons
* * tests/var.test:hobbs1999-12-121-35/+52
| | | | | | | | | | | | | | | | | | | | | | | | | * generic/tclCompile.c: fixed problem where setting to {} array would intermittently not work. (Fontaine) [Bug: 3339] * generic/tclCmdMZ.c: * generic/tclExecute.c: optimized INST_TRY_CVT_TO_NUMERIC to recognize boolean objects. (Spjuth) [Bug: 2815] * tests/info.test: * tests/parseOld.test: * generic/tclCmdAH.c: * generic/tclProc.c: changed Tcl_UplevelObjCmd (uplevel) and Tcl_EvalObjCmd (eval) to use TCL_EVAL_DIRECT in the single arg case as well, to take advantage of potential pure list input optimization. This means that it won't get byte compiled though, which should be acceptable. * generic/tclBasic.c: made Tcl_EvalObjEx pure list object aware in the TCL_EVAL_DIRECT case for efficiency. * generic/tclUtil.c: made Tcl_ConcatObj pure list object aware, and return a list object in that case [Bug: 2098 2257] * generic/tclMain.c: changed Tcl_Main to not constantly reuse the commandPtr object (interactive case) as it could be shared.

The optimization was removed, which means that: expr 1 + {[string length abc]} will be not be compiled inline as before, but this should be written: expr {1 + [string length abc]} which will be compiled inline for speed. This prevents expr 1 + {[mindless error]} from seg faulting, and only affects optimizations for degenerate cases [Bug: 3737]
