936bd3c902 * fixed definitions/uses of asmsymbols: always explicitly define local
symbols as local, don't use RefAsmSymbol for symbols that may still
    be defined/used as local symbols later

fcaff0489c * psub.pas : translate tregister for registerhi also
(avoids imaginary register number in "# Var I in register .." assembler comments.
  * dbgdwarf.pas : Support register variables as register pairs.
      Does not yet handle case of changing registers.
  * symsym.pas : add currentregloc field to tabstractnormalvarsym class,
     to be able to track changing registers used for a given variable.
  * aasmtai.pas : Update currentregloc field of tai_varloc.create sym parameter.
  * ncgutil.pas : Only generate a tai_varloc if the new registers are different for the variable.

14cfe770a4 * replaced most (if not all) remaining fields/parameters in the compiler
that deal with paths/filenames with TPathStr (= ansistring) to prevent
    cutting off long paths (no change in speed when compiling the compiler,
    1% extra memory usage)

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1
     to the make command line

28740dce2d - removed extra "fordefinition" parameter again from tprocdef.mangledname(),
since the definition-specific adorning of JVM mangled names is Jasmin-
    specific, and such code has no place in symdef

0ee702b3a2 * tprocdef.mangledname now gets an extra boolean parameter indicating
whether the mangled name is for defining a symbol, or for referencing
    it later (e.g. for a call or load of its address). The reason is that
    on the JVM both cases are different.
  + jvmdef unit to encode types according to the JVM rules
  + tprocdef.jvmmangledname() to encode a procdef's JVM mangled name
    (the common part of defining/referencing it; tprocdef.mangledname
     afterwards adorns it as required)

96116a6c3a Several adjustments because virtual methods in helpers are just normal methods and a VMT isn't generated for them either.
* $CPU/cgcpu.pas: disable the generation of VMT loading code
* dbgstabs.pas, dbgdwarf.pas: treat virtual methods of helpers as normal methods
* ncgcal.pas: don't register virtual helper methods for WPO 
* ncgrtti.pas: write virtual helper methods as normal methods to RTTI
* nobj.pas: correctly handle final and override cases in helpers
* pdecvar.pas: property getters
* rautils.pas: no VMT offset in records

     - The (hidden) pointer is dereferenced
     - The class is marked as unallocated when the (hidden) pointer is nil

  - use struct_property_dec in record parser
  - change structh type from objectdef to abstractrecorddef in read_property_dec to use by records
  - disallow stored and default modifiers for records because records are not used for streaming

56bf42de57 compiler: implement record methods and class methods:
- rename tprocdef._class to tprocdef.struct and change the type from tobjectdef to tabstractrecorddef because methods can belong not to classes only now but to records too
  - replace in many places use of current_objectdef to current_structdef with typcast where is needed
  - add an argument to comp_expr, expr, factor, sub_expr to notify that we are searching type only symbol to solve the problem with records,objects,classes which contains fields with the same name as previosly declared type (like:
  HWND = type Handle;
  rec = record 
    hWnd: HWND;
  end;)
  - disable check in factor_read_id which was made for object that only static fields can be accessed as TObjectType.FieldName outside the object because it makes SizeOf(TObjectType.FieldName) imposible and since the same method was extended to handle records it also breaks a52 package compilation
  - rename tcallcandidates.collect_overloads_in_class to tcallcandidates.collect_overloads_in_struct and addapt the code to handle overloads in records too
  - fix searchsym_type to search also in object ancestors if we found an object symtable
  - add pd_record, pd_notrecord flags to mark procedure modifies which can or can't be used with records. Disallow the next modifiers for records: abstract, dynamic, export, external, far, far16, final, forward, internconst, internproc, interrupt, message, near, override, public, reintroduce, virtual, weakexternal,
Allow the next modifiers for records: static

57bd6d2685 + merged nestedprocvars branch
+ support for nested procedural variables:
    o activate using {$modeswitch nestedprocvars} (compatible with all
      regular syntax modes, enabled by default for MacPas mode)
    o activating this mode switch changes the way the frame pointer is
      passed to nested routines into the same way that Delphi uses (always
      passed via the stack, and if necessary removed from the stack by
      the caller) -- Todo: possibly also allow using this parameter
      passing convention without enabling nested procvars, maybe even
      by default in Delphi mode, see mantis #9432
    o both global and nested routines can be passed to/assigned to a
      nested procvar (and called via them). Note that converting global
      *procvars* to nested procvars is intentionally not supported, so
      that this functionality can also be implemented via compile-time
      generated trampolines if necessary (e.g. for LLVM or CIL backends
      as long as they don't support the aforementioned parameter passing
      convention)
    o a nested procvar can both be declared using a Mac/ISO Pascal style
      "inline" type declaration as a parameter type, or as a stand-alone
      type (in the latter case, add "is nested" at the end in analogy to
      "of object" for method pointers -- note that using variables of
      such a type is dangerous, because if you call them once the enclosing
      stack frame no longer exists on the stack, the results are
      undefined; this is however allowed for Metaware Pascal compatibility)

daef2efa69 - removed tstoreddef.reset() and overrides, and the associated
reset_used_unit_defs()/reset_all_defs() calls:
    o removed resetting tprocdef.procstarttai/procendtai and
      instead check in the debug writers whether the def is
      in the current unit or not to determine whether we should
      write debug info for it
    o use the collected defs in the wpoinfo structure to reset
      the wpo flags in the defs, instead of iterating over all
      defs in the program and resetting them that way
  - removed now unused "is_reset" flag from tmodule
