avoid unnecessary string copies.

optimisation for concatting an empty string. This enables
replacing the idiom 'K $x [set x {}]' by '$x[set x {}]' for
fastest execution.

properly have tclIntType used for smaller values. This corrects
TclX bug 896727 and any other 3rd party extension that created
math functions but was not yet WIDE_INT aware in them.

* generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
automatic variables, defining them in tight blocks instead of at
the function level. This has three purposes:
- it simplifies the analysis of individual instructions
- it is preliminary work to the non-recursive engine
- it allows a better register allocation by the optimiser; under
gcc3.3, this results in up to 10% runtime in some tests
|
|
|
|
| |
classify the variables according to their use in TEBC.

* generic/tclExecute.c (TclExecuteByteCode): remove one level of
indirection for compiledLocals addressing.

indirection for compiledLocals addressing.
|
|
|
|
|
| |
(DE)CACHE_STACK_INFO pair around the call - the user defined math
function could cause a recursive call to TEBC.
|
|
|
|
|
|
| |
* generic/tclExecute.c (INST_START_CMD): interp deletion now
modifies the compileEpoch, eliminating the need for the check for
interp deletion in INST_START_CMD.

* generic/tclCompile.c:
* generic/tclExecute.c: changed implementation of {expand}, last
chance while in alpha as ...
***POTENTIAL INCOMPATIBILITY***
Scripts precompiled with ProComp under previous tcl8.5a versions
may malfunction due to changed instruction numbers for
INST_LIST_INDEX_IMM, INST_LIST_RANGE_IMM and INST_START_CMD.
|
|
|
|
|
|
|
| |
* generic/tclCompile.h: the math functions receive a pointer to
top of the stack (tosPtr) instead of the execution environment
(eePtr). First step towards a change in the execution stack
management - it is now only used within TEBC.
|
| |
|
|
|
|
|
|
|
|
|
| |
* generic/tclCompile.c (TclCompileScript): avoid emitting
INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It
is not needed, as the checks are done before calling TEBC.
* generic/tclExecute.c (TclExecuteByteCode): runtime peephole
optimisation: check at INST_POP if the next instruction is
INST_START_CMD, in which case we fall through.

* generic/tclInt.h: Reworked the Tcl header files into a clean
* unix/tclUnixPort.h: hierarchy where tcl.h < tclPort.h < tclInt.h
* win/tclWinInt.h: and every C source file should #include
* win/tclWinPort.h: at most one of those files to satisfy its
declaration needs. tclWinInt.h and tclWinPort.h also better organized
so that tclWinPort.h includes the Windows implementation of
cross-platform declarations, while tclWinInt.h makes declarations that
are available on Windows only.
* generic/tclBinary.c (TCL_NO_MATH): Deleted the generic/tclMath.h
* generic/tclMath.h (removed): header file. The internal Tcl
* macosx/Makefile (PRIVATE_HEADERS): header, tclInt.h, has a
* win/tcl.dsp: #include <math.h> directly,
and file external to Tcl needing libm should do the same.
* win/Makefile.in (WIN_OBJS): Deleted the win/tclWinMtherr.c file.
* win/makefile.bc (TCLOBJS): It's a vestige from matherr() days
* win/makefile.vc (TCLOBJS): gone by.
* win/tcl.dsp:
* win/tclWinMtherr.c (removed):

* generic/tclCompile.h: that allows checking the bytecode's
* generic/tclExecute.c: validity [Bug 729692] and the interp's
* tests/interp.test (18.9): readyness [Bug 495830] before running
* tests/proc.test (7.1): the command. It also changes the
* tests/rename.test (6.1): mechanics of the async tests in TEBC,
doing it now at command start instead of every 16 instructions.

such as [return -code error $msg] to be bytecompiled.
* generic/tclInt.h: Factored Tcl_ReturnObjCmd() into two pieces:
* generic/tclCmdMZ.c: TclMergeReturnOptions(), which can parse the
options to [return], check their validity, and create the
corresponding return options dictionary, and TclProcessReturn(),
which takes that return options dictionary and performs the
[return] operation.
* generic/tclCompCmds.c: Rewrote TclCompileReturnCmd() to
call TclMergeReturnOptions() at compile time so the return options
dictionary is computed at compile time (when it is fully known).
The dictionary is pushed on the stack along with the result, and
the code and level values are included in the bytecode as operands.
Also supports optimized compilation of un-[catch]ed [return]s from
procs with default options into the INST_DONE instruction.
* generic/tclExecute.c: Rewrote INST_RETURN instruction to retrieve
the code and level operands, pop the return options from the stack,
and call TclProcessReturn() to perform the [return] operation.
* generic/tclCompile.h: New utilities include TclEmitInt4 macro
* generic/tclCompile.c: and TclWordKnownAtCompileTime().

* doc/Tcl.n: of the new leading {expand} syntax on words.
* generic/tcl.h: Parses such words as the new Tcl_Token type
* generic/tclBasic.c: TCL_TOKEN_EXPAND_WORD. Updated Tcl_EvalEx
* generic/tclCompile.c: and the bytecode compiler/execution engine
* generic/tclCompile.h: to recognize the new token type. New opcodes
* generic/tclExecute.c: INST_LIST_VERIFY and INST_INVOKE_EXP and a new

* generic/tclTest.c: and tests are included.

* library/package.tcl: argument expansion with the new syntax.

* tests/cmdInfo.test: replaced use of [eval] to force direct
* tests/encoding.test: string evaluation with use of [testevalex]
* tests/execute.test: which more directly and robustly serves the

that appends a Tcl_Obj to the errorInfo, saving the caller the trouble
of extracting the string rep.
* generic/tclStringObj.c (TclAppendLimitedToObj): New internal
routine that supports truncated appends with optional ellipsis marking.
This single routine supports UTF-8-safe truncated appends needed in
several places throughout the Tcl source code, mostly for error and
stack messages. Clean fix for [Bug 760872].

* generic/tclObj.c is defined on all platforms, even those where
* generic/tclPort.h TCL_WIDE_INT_IS_LONG is defined. Also made
the Tcl_Value struct have a wideValue field on all platforms. This is
a ***POTENTIAL INCOMPATIBILITY*** for TCL_WIDE_INT_IS_LONG platforms
because that struct changes size. This is the same TIP 72
incompatibility that was seen on other platforms at the 8.4.0 release,
when this change should have happened as well. [Bug 713562]
* generic/tclInt.h: New internal macros TclGetWide() and
TclGetLongFromWide() to deal with both forms of the "wideInt"
Tcl_ObjType, so that conditional TCL_WIDE_INT_IS_LONG code
is confined to the header file.
* generic/tclCmdAH.c: Replaced most coding that was conditional
* generic/tclCmdIL.c: on TCL_WIDE_INT_IS_LONG with code that
* generic/tclExecute.c: works across platforms, sometimes using
* generic/tclTest.c: the new macros above to do it.
