* general PCODE cleanup and address most of TODO/TOFIX notes in
source code:
! fixed GPF traps when too long string or codeblock is generatd
+ added support for 16MB codeblocks and strings
! removed macrocompiler limitation for jumps range
! fixed GPF when more then 255 local variables is used and added
support for 2^15 locals
! removed all strtok() functions
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is variable or array item
% added optimization for all +=, -=, *=, %=, ^=, **= operations
when left side of expression is object method and updated ++, --
for new code. It's still disabled until we will not add support
for late evaluated reference items to HVM
! fixed a[++i]++ and similar operations (a[++i]*=2, ...). Now ++i is
executed only once. It's not Clipper compatible but it was in
TODO note in source code. It can be disabled by -kc option
* finished support to xHarbour like #pragma TEXTHIDDEN(1)
! fixed local add int optimization when PARAMETERS used after
optimization changed local variable number over 255
! fixed GPF trap when in HB_P_<op>EQ PCODEs when executed for
direct values
* others
! fixed problems reported by Chen
* optimized strtran(), left(), right() to not create new string copy
when the same value is returned
