* Added new tools for managing and verifying the stack depth during ↵mig2013-12-231-0/+15
| | | | compilation. Used it in some spots in the compiler and in TclCompileCatchCommand.
* remove INST_TRY_CVT_TO_NUMERIC when it is known not be necessary (cherrypick ↵mig2013-12-201-0/+12
| | | | from mig-optimize)
* Add TclRegisterLiteral() to internal stub table (from "mig-optimize" branch, ↵jan.nijtmans2013-12-191-2/+0

* Making the optimizer pluggable by extensions; please review for committing ↵mig_tmp_optimizemig2013-12-181-1/+1

* Stop printing undefined values in disassembled code.dkf2013-12-061-0/+1

* New compiler and bytecodes for foreach and lmap: 70% faster mig2013-12-051-3/+9
| | | | | | | | | * speed as measured by http://wiki.tcl.tk/39021: runs in <1/3 the time * still need to adapt array-set to use this * assemble.test-16.5 or 16.6 bombs in a purify/symbols build (?) * removing the old opcodes would force recompilation of old .tbc files or adaptation of tbcload

* Remove Tcl_Preserve support for ContLineLoc values. It's not needed.dgp2013-08-071-4/+0

* Eliminate the litInfo table and all the code tending to its care and feeding.dgp2013-07-161-8/+0
| | | | The pc -> command index mapping function it provided can be achieved using other data already in the ByteCode struct.

* Stop emitting the instructions INST_*_SCALAR_STK*. They are identical todgp2013-05-291-5/+4
| | | | | | | their INST_*_STK* counterparts. Having done that, it is clear the "simpleVarName" return from TclPushVarName provides nothing of use to any of its callers. Eliminate that. Also make TPVN return void, instead of int. Bring the TPVN header comments up to date; they were quite rotten.
