* * generic/tclExecute.c (INST_LIST_RANGE_IMM): Enhance implementationdkf2012-02-161-2/+23
| | | | so that shortening a (not multiply-referenced) list by lopping the end off with [lrange] or [lreplace] is efficient.
* Make some of the logic in TclCompileObj less heavily nested, to improve clarity.dkf2011-11-221-99/+98

* Fix a bug where global precompiled code (A) called from a precompiled andreask2011-11-211-7/+9
| | | | | | | | | | | | | | | | | | | | procedure causes the core to recompile (A), triggering the trap laid inside, i.e. 'error "called a copy of compiled code"'. <pre>Example ----------------------ex1.tcl proc init {} { source ex2.tcl } init ----------------------ex2.tcl puts a ----------------------</pre> When run as precompiled code the 'puts a' is not executed, only the trap. Fixed by enclosing the offending code into a guard which prevents its execution for precompiled code. The change passes the entire testsuite.
* Added support for having the dict var itself referenced by LVT index.dkf2011-10-031-13/+47

The code here is much simpler (trimmed down) compared to the head as the 8.4 branch is not bytecode compiling whole files, and doesn't compile eval'd code either. Reworked the handling of literal command arguments in bytecode to be saved (compiler) and used (execution) per command (See the TCL_INVOKE_STK* instructions), and not per the whole bytecode. This removes the problems with location data caused by literal sharing in proc bodies. Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex).
