* * generic/tclExecute.c (TEBC): disable the new shortcut to frequentMiguel Sofer2007-08-221-2/+4
| | | | INSTs for debug builds.
* * generic/tclExecute.c (INST_SUB): fix usage of the new macro forMiguel Sofer2007-08-201-3/+10
| | | | | overflow detection in sums, adapt to subtraction. Lenghty comment added.
* Swapped the order in the Overflowing macro (created in the last commit byMiguel Sofer2007-08-191-2/+5
| | | | Donal): check first the condition most likely to fail in its usage by [incr].
* Make Miguel's overflow-detection more mnemonic with a macro.dkf2007-08-191-73/+86

* * 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/tclExecute.c (INST_STORE_ARRAY):Miguel Sofer2007-08-091-24/+13

* * generic/tclBasic.c (TEOvI, GetCommandSource):Miguel Sofer2007-07-241-34/+16
| | | | | | | | | | * 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/tclBasic.c: Removed dead code, including thedgp2007-06-281-237/+1

| | | | | | | * generic/tclInt.h: parallel (and fall back on) Tcl_Realloc. * generic/tclNamesp.c (TclResetShadowesCmdRefs): Replaced ckrealloc based allocations with TclStackRealloc allocations.

| | | | | | | * generic/tclExecute.c (INST_INVOKE): traces that were created * tests/trace.test (trace-36.2): during execution of an originally untraced command do not fire [Bug 1740962], partial fix.
* * generic/tclInt.decls: Revised the interfaces of the routinesdgp2007-06-201-10/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * generic/tclExecute.c: TclStackAlloc and TclStackFree to make them easier for callers to use (or more precisely, harder to misuse). 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. TSA/TSF also now tolerate receiving (interp == NULL), in which case they simply fall back to be calls to Tcl_Alloc/Tcl_Free. * generic/tclIntDecls.h: make genstubs * generic/tclBasic.c: Updated callers * generic/tclCmdAH.c: * generic/tclCmdIL.c: * generic/tclCompCmds.c: * generic/tclCompExpr.c: * generic/tclCompile.c: * generic/tclFCmd.c: * generic/tclFileName.c: * generic/tclIOCmd.c: * generic/tclIndexObj.c: * generic/tclInterp.c: * generic/tclNamesp.c: * generic/tclProc.c: * generic/tclTrace.c: * unix/tclUnixPipe.c:

| | | | | | | * generic/tclCmdMZ.c (Tcl_SwitchObjCmd): * generic/tclCompile.c (TclInitCompileEnv): * generic/tclProc.c (Tcl_ProcObjCmd, SetLambdaFromAny): Moved the CmdFrame off the C stack and onto the Tcl stack.
* * generic/tclExecute.c (TEBC): Moved the CmdFrame off the C stackMiguel Sofer2007-06-181-19/+20

| | | | | | | | | | | | * generic/tclExecute.c: INST_INVOKE to essentially what they were * generic/tclBasic.c: previous to the commit of 2007-04-03 [Patch 1693802] and the subsequent optimisations, as they break the new trace tests described below. * generic/trace.test: added tests 36 to 38 for dynamic trace creation and addition. These tests expose a change in dynamics due to a recent round of optimisations. The "correct" behaviour is not described in docs nor TIP 62.

* * generic/tclExecute.c (TclCompEvalObj): missed update to "thereMiguel Sofer2007-06-141-6/+2
| | | | | | | | | is always a valid frame". * generic/tclProc.c (TclObjInterpProcCore): call TEBC directly instead of going through TclCompEvalObj - no need to check the compilation's freshness, this has already been done. This improves speed and should also provide some relief to [Bug 1066755].

| | | | | | | * generic/tclCompile.h: TclEvalObjvKnownCommand() function to * generic/tclExecute.c: handle commands that are already known and are not traced. INST_INVOKE now calls into this function instead of inlining parts of TEOvI. Same perf, better isolation.

Also spli TEOvI in a full version that handles non-existing and traced commands, and a separate shorter version for the regular case. * generic/tclBasic.c: Moved the generation of command strings for * generic/tclTrace.c: traces: previously in Tcl_EvalObjv(), now in TclCheck[Interp|Execution]Traces(). Also insured that the strings are properly nul terminated at the correct length [Bug 1693986] * generic/tclBasic.c: Extend usage of TclLimitReady() and * generic/tclExecute.c: (new) TclLimitExceeded() macros. * generic/tclInt.h: * generic/tclInterp.c: * generic/tclInt.h: New TclCleanupCommandMacro for core usage. * generic/tclBasic.c: * generic/tclExecute.c: * generic/tclObj.c:
