| | | | | * tests/expr-old.test: fix for erroneous error messages in [expr], [Bug 587140] reported by Martin Lemburg.

* * generic/tclExecute.c: restoring the tcl_traceCompile functionalityMiguel Sofer2002-07-241-1/+7
| | | | | | while I repair tcl_traceExec. The core now compiles and runs also under TCL_COMPILE_DEBUG, but execution in the bytecode engine can still not be traced.
* Allowed parser to recognise 'Inf' as a floating-point number. [Bug 218000]dkf2002-07-221-2/+19

| | | | | | non-immediate INST_INCR instructions; elimination of 103 (!) TclDecrRefCount macros. The different instructions now jump back to a common "DecrRefCount zone" at the topof the loop.
* generic/tclExecute.c (TEBC, INST_DONE): small bug in the panic codeMiguel Sofer2002-06-181-1/+2

* runtime peep-hole optimisation of variables (INST_STORE, INST_INCR)Miguel Sofer2002-06-141-10/+45

* consolidated opcodes in the bytecode engine, eliminating duplicatedMiguel Sofer2002-06-131-474/+200

* reverting an accidental modification in the last commit.Miguel Sofer2002-06-031-61/+1

* clarify the empty variable name issue ([Bug 549285])Miguel Sofer2002-06-031-1/+61
|
* * Removed internal routinedgp2002-05-311-61/+1
| | | | | | | | TclMathInProgress and Unix implementation of matherr(). These are now obsolete, dealing with very old versions of the C math library. Windows version is retained in case Borland compilers require it, but it is inactive. Thanks to Joe English. [Bug 474335, Patch 555635].
* * generic/tclExecute.c (TclExecuteByteCode INST_STR_CMP):hobbs2002-05-301-6/+6
| | | | | | | * generic/tclCmdMZ.c (Tcl_StringObjCmd): changed the case for choosing the Tcl_UniCharNcmp compare to when both objs are of StringType, as benchmarks show that is the optimal check (both bigendian and littleendian systems).
* 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.
* fix for [Bug #542588], where "too large integers" were reported asMiguel Sofer2002-04-181-12/+20
| | | | "floating-point value" in [expr] error messages.
* made bytecodes check for a catch before returning; the compiled [return] is ↵Miguel Sofer2002-04-151-10/+12
| | | | otherwise non-catchable. [Bug 542588]
* * Corrected problems with Tcl_AllowExceptionsdgp2002-03-291-30/+16
| | | | | having influence over the wrong scope of Tcl_*Eval* calls. Patch from Miguel Sofer. Report from Jean-Claude Wippler. [Bug 219181]
* fixed the errorInfo for return codes other than (TCL_OK, TCL_ERROR) toMiguel Sofer2002-03-221-62/+4
| | | | | runLevel 0 [Bug 533758]. Removed the static RecordTracebackInfo(), as its functionality is easily replicated by Tcl_LogCommandInfo.
* Replaced a few direct stack accesses with the POP_OBJECT() macro [Bug 507181]Miguel Sofer2002-02-281-15/+13

* * tclExecute.c:andreas_kupries2002-02-151-2/+2
| | | | | | | * tclIOGT.c: * tclIndexObj.c: Touchups to the TIP 72 patch to make it compileable under Windows again. The changes are not complete, there is one nasty regarding _stati64
* TIP#72 implementation. See ChangeLog for details.dkf2002-02-151-357/+942
| | | | | This version builds clean on Solaris/SPARC, with GCC and CC, both with and without threads and both in 32-bit and 64-bit mode.
