* harbour/include/hbexprb.c
* do not generate HB_P_FUNCPTR - it's not longer necessary
+ added optimization for <exp> + 1, <exp> - 1 - disabled by default
because it changes error messages in hbtest, code like NIL + 1
generates 'argument error ++' instead of 'argument error +'. I'd like
you will decide what you prefer - faster code or strict Clipper error
messaged.
* harbour/source/common/expropt2.c
+ added optimizations for <num> + <date>
+ added ooptimizations for <exp> + 0, 0 + <exp>, <exp> - 0
This is also sth what may interact with operators overloading in object
system. When we will have strong typing then we should think about an
option which will optionally disable some optimizations - someone may
want to define arithmetic where <obj> + 0 gives differ then <obj>
results.
* harbour/include/hbcomp.h
* harbour/source/compiler/harbour.c
* harbour/source/compiler/harbour.y
* harbour/source/compiler/harbour.yyc
* harbour/source/compiler/harbour.yyh
+ added hb_compStatmentStart()
! restrict MEMVAR and FIELD usage - now they have to be located before
executable statements like in Clipper.
! generate error when PARAMETERS is used as file wide declaration.
! generate errors when different executable statements are used before
first procedure - now such code was simply ignored without any errors.
! generate valid error messages when some declarations are used in
wrong places
! fixed setting begin of executable statement flag in different .prg
constructions.
