* * Updated interfaces of generic/tclEncoding, generic/tclFilename.c,dgp2002-01-251-2/+2
| | | | | | | | | | | generic/tclIOUtil.c, generic/tclPipe.c, generic/tclResult.c, generic/tclUtil.c, generic/tclVar.c and mac/tclMacResource.c according to TIP 27. Tcl_TranslateFileName rewritten as wrapper around VFS-aware version. Updated callers. ***POTENTIAL INCOMPATIBILITY*** Includes source incompatibilities: argv arguments of Tcl_Concat, Tcl_JoinPath, Tcl_OpenCommandChannel, Tcl_Merge; argvPtr arguments of Tcl_SplitList and Tcl_SplitPath.

| | | | | | ability of the [lindex] command to have multiple index arguments, and adds the [lset] command. Both commands are byte-code compiled. [Patch #471874] (work by Kenny, commited by Hobbs)
* * generic/tclInt.decls (TclExpandCodeArray,TclGetInstructionTable):andreas_kupries2001-10-151-4/+7
| | | | | | | | | | Added to internal stubs table. Tclcompiler (Tclpro project) needs them if used as loadable package under Windows. Changed signatures. We don't want to describe compiler internal structures in "tclInt.h". * generic/tclCompile.h: S.a. Removed function declarations. * generic/tclCompile.c: S.a. Adapted to changed signatures.
* * generic/tclExecute.c (TclExecuteByteCode):hobbs2001-09-191-3/+3
| | | | | | | | * generic/tclCompile.c (instructionTable): * generic/tclCompCmds.c (TclCompileStringCmd): INST_STR_MATCH - Updated to Int1 instruction type and added special case to use INST_STR_EQ instead when no glob chars are specified in a static string.

* * generic/tclBasic.c: added new CompileProc invocations to basichobbs2001-05-171-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/tclCompExpr.c: changed INST_STREQ -> INST_STR_EQ,hobbs2000-05-261-145/+157
| | | | | | | | | | | | | | | INST_STRNEQ -> INST_STR_NEQ * generic/tclCompile.c: added streq, strneq, strcmp, strlen & strmatch to the compiled stats instructionTable * generic/tclCompile.h: added instructions INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH * generic/tclCompCmds.c: added byte compiler support for [string compare|match|index]. * generic/tclExecute.c: Changed INST_STR_(N)EQ to return an Int object and not bother trying to reuse the top stack object. Added INST_STR_CMP, INST_STR_INDEX, INST_STR_MATCH bytecode ops. Extended evalstats output info with Tcl_IsShared stat info.
* * generic/tclCompile.c (TclCleanupByteCode): made ByteCode cleanuphobbs2000-03-301-2/+19
| | | | | | | | more aware of TCL_BYTECODE_PRECOMPILED flagged structs (gen'd by tbcload), to correctly clean them up. * generic/tclClock.c (FormatClock): moved check for empty format earlier, commented 0 result return value
* * tests/var.test:hobbs1999-12-121-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | * 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. (Fellows)

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]

Added test cases.

| | | | | | | | | | | * generic/tclInt.decls: * generic/tclCompile.c: Added TclSetByteCodeFromAny that takes a hook procedure to invoke after compilation but before the byte codes are emitted. This makes it possible to do postprocessing on the compiled byte codes before the ByteCode is generated. * generic/tclLiteral.c: Added TclHideLiteral and TclAddLiteralObj to make it possible to create local unshared literal objects.
