88af293155 Fix for Mantis #22160
The cause of the internal error was the following:
We have a generic in an unit ("A") which uses another unit ("B") in the implementation section and this other unit uses unit A in the interface section. Now the generic is specialized in the interface section of B. This leads to the problem that in unit A when it tries to load the globalsymtable of unit B that globalsymtable will be Nil, because parsing of the interface section is not yet finished. Thus the change in pgenutil.pas, specialization_init: if the unit is still "in_interface" the localsymtable needs to be used instead of the globalsymtable.

This doesn't necessarily lead to a compiling test though, as there is the following possibility:
Unit A contains a generic class/record (with methods) and uses unit B in the implementation section. This unit B also contains a generic class/record (with methods) and uses unit A in the implementation section. Both units contain a specialization of the other unit's generic outside of it's own generics (such that generate_specialization is fully triggered). Let's assume compilation starts with unit A and we reach the uses of unit B. Now compilation switches to unit B and completes as unit A is already registered and in compilation. The problem now is that the generic in unit A still contains unresolved forward declarations as the implementation section of A was not yet parsed which will lead to "forward declaration not solved" errors (Note: Delphi compiles this).

The solution to this is the following: if a generic is specialized from another unit which is not in state ms_compiled then the unit of the specialization needs to wait for the unit of the generic. So the specialization's unit adds itself into a list of waiting units of the generic's unit. Now inside "proc_unit" we need to check whether this module is waiting for other modules and if so avoid "finishing" the unit (which means generating the methods of the specialization, generating assembler code and ultimately freeing the scanner and PPU). Now when the generic's unit finishes we need to check whether other modules are waiting for it and finish them (of course it's a bit more complicated in reality, but that pretty much sums it up).

+ globstat.pas: Added an unit which handles the saving and restoring of the global state which was originally inside "parser.pas, compile" so that Don't Repeat Yourself (DRY) is respected.
* fmodule.pas, tmodule: 
  + add fields to keep track of the units the module is waiting for and which modules are waiting for the module
  + add field for the saved global state (raw pointer to avoid circles)
  + add field for the state which is needed to finish the unit (raw pointer to avoid circles)
  + move the code which was used in "parser.pas, compile" after a module was successfully compiled to the new virtual method "end_of_parsing"
+ fppu.pas, tppumodule.end_of_parsing:
  free the ppufile here
* pgenutil.pas:
  + add new procedure "maybe_add_waiting_unit" which adds the specialization's unit to the waiting list of the generic if that unit is not yet compiled
  * generate_specialization: call the new function when we add a new (true) specialization
  * specialization_init: instead of not adding implementation units at all check whether the unit is still parsing the interface section and add the localsymtable in that case
* pmodules.pas:
  * change "proc_unit" to a function which returns "true" if the unit was already finished (no need to wait for other units)
  + move the code from "proc_unit" from "generate_specialization_procs" on to a new procedure "finish_unit" which
  * this procedure is either called immediately in "proc_unit" if the unit does not need to wait for other units or from "finish_unit" itself if a unit that is waiting for the given unit does no longer wait for another module (special care is taken in proc_unit to avoid circles)
* parser.pas, compile:
  * correctly handle the case if an unit is not finished
  * use the new global state functionality from globstat.pas
  * pay special attention when calling "set_current_module" (see comment at that call)

+ add tests from 22160
+ add test for above mentioned "diamond" case

3380b58695 * when we get near the limit of the maximum number of TOC entries that can
be generated for a single object file on AIX, automatically switch to
    an indirection scheme that uses much less TOC entries, but is slower to
    access global variables
  * manually merged infrastructure for target-specific code generation
    switches from JVM branch (-CTxxx switches)
  * -CTsmalltoc switch for AIX that forces the indirection scheme for TOC
    entries from the start in case the automatic one does not conserve
    a sufficient amount (or in case you bump up against the global TOC
    entries limit during linking)

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

  - add helper function getansistringdef which return a def with explicitly set codepage or cansistringtype in other case
  - change tstoreddef.createnai constructor to allow set codepage in constructor
  - don't convert string constants to rawbytestring. if string constant already has a codepage - preserve it or convert to ansistring codepage (delphi compatible)
  - don't perform string conversion from ansistring to strings with explicitly set codepage (by directive or by compiler switch) and vice versa (delphi compatible)
  + test which covers most of the cases

43c5ed20c2 + support for initialising typed constants via compiler-generated
assignment-nodes. For global typed constants and typed constants/
    local variable initialisers in regular functions/procedurs, the
    assignments are performed in the unit initialisation code. For
    those in object/record definitions and their methods, it's done
    in the class constructor. Since we may not yet have parsed all
    method implementations when the class constructor is parsed, part
    of these may be initialised in a helper routine called from the
    class constructor. The ones known when the class constructor is
    parsed are inited there, because the ones marked as "final" and
    declared as static class fields must be initialised in the class
    constructor for Java
   o new set systems_typed_constants_node_init in systems unit that
     indicates that a target uses node trees to initialise typed consts
     instead of an initialised data section
   o mark typed constants in {$j-} mode as "final" for JVM
   o mangle the name of staticvarsyms inside localtables a bit to avoid
     name clashes (only with procedure names for now, no parameters yet
     so can still cause problems with overloaded routines)
   o after a routine has been parsed, it is now processed by
     cnodeutils.wrap_proc_body(), which can add extra nodes before code
     generation (used for injected the typed constant node trees)

1c01d52ea6 * Improvements of tprocinfo class:
* Moved nestedprocs from tcgprocinfo to tprocinfo, in order to be able to access the entire nested procedure hierarchy without depending on psub.pas or code generator.
  * Creating an instance of tprocinfo automatically inserts it into list of parent's nested procedures.
  * nestedprocs list is created on demand. Public read-only access is provided by has_nestedprocs and get_first_nestedproc functions.
  + Method destroy_tree is provided for destroying the entire hierarchy of procinfo's. It can be called on any procinfo object in the tree.
  + Also added methods save_jump_labels and restore_jump_labels for asmlabel maintenance, which is currently being repeatedly done all over the codegenerator.

f7f357f18e * symconst.pas:
- remove thelpersearch again => adjustments to searchsym_in_class and calls to it
- rename sto_has_classhelper to sto_has_helper
* symbase.pas: make push and pop in tsymtablestack virtual
* symdef.pas:
- add a new class tdefawaresymtablestack which overrides push and pop of tsymtablestack and adjusts the new extendeddefs field of the current tmodule
- tobjectdef.create: sto_has_classhelper => sto_has_helper
* fmodule.pas:
- add new hash object list to tmodule (key: mangled type name) which holds object list instances that contain all helpers currently active for a given type (= key of the hash list)
- tmodule.create: the hash list owns the sublists (but those don't own the defs)
- tmodule.destroy: free the hash list
* pdecobjpas:
- rename parse_extended_class to parse_extended_type
- parsing of constructors:
# for all helper types: no class constructors allowed
# for record helpers: as long as constructors for records themselves are disabled they are for record helpers as well
- object_dec: manually add the helper to the extendeddefs if the overall owner of the current def is a static symtable (implementation section or program/library main file), because the symtable won't be popped and pushed then
* parser.pas: instantiate the new stack class
* psub.pas: backup the extendeddefs in specialize_objectdefs as well
* ptype.pas:
- generate_specialization: backup the extendeddefs as well
- record_dec: _RECORD is now consumed in read_named_type itself
- read_named_type: parse "record helper" if advanced record syntax is enabled
* symtable.pas:
- correct searchsym_in_class declaration => adjustments in this unit as well
- add the possibility to pass a context def to search_last_objectpascal_helper
- rename search_objectpascal_class_helper to search_objectpascal_helper
- rename search_class_helper to search_objc_helper
- searchsym_in_class: 
# search for helpers in every level of the tree of the class
# the contextclassh can also be a subclass of the extendeddef
- searchsym_in_record: search for helper methods as well
- searchsym_in_helper:
# search for symbols in class and record helpers is the same except for the search in the class' ancestors
# search the extendeddef directly and rely on searchsym_in_class only for the class' ancestors as we need to find the helpers there as well
- search_last_objectpascal_helper: use the extendeddefs list of current_module instead of scanning the symbol stack itself
* pexpr.pas: adjustments because of renaming of sto_has_classhelper
* pinline.pas: adjustment because of removing of thelpersearch
* nflw.pas: 
- renamed classhelper to helperdef
- adjusted search_last_objectpascal_helper call
* msg*:
- adjusted error message for constructors in records (this currently applies to record helpers as well)
- renamed parser_e_not_allowed_in_classhelper to parser_e_not_allowed_in_helper => adjustments in code
- added parser_e_no_class_constructors_in_helpers
* pdecsub.pas: adjusted renamed error message
* htypechk.pas: check for helpers in every step of the hierarchy
* nobj.pas: search_class_helper => search_objc_helper
* utils/ppudump.pas: adjust, because of renames

Note: the define "useoldsearch" will be only used for performance comparison on my (faster) Linux machine; that (and its associated code) will be removed afterwards

  + initial implementation of whole-program optimisation framework
  + implementation of whole-program devirtualisation
  o use:
     a) generate whole-program optimisation information (no need
        to completely compile the program and all of its units
        with -OW/-FW, only the main program is sufficient)
      fpc -OWdevirtcalls -FWmyprog.wpo myprog

      fpc -B -Owdevirtcalls -Fwmyprog.wpo myprog
     (the -B is not required, but only sources recompiled during
      the second pass will actually be optimised -- if you want,
      you can even rebuild the rtl devirtualised for a particular 
      program; and these options can obviously also be used         
      together with regular optimisation switches)
  o warning:
    - there are no checks yet to ensure that you do not use 
      units optimised for a particular program with another

  * extracted code to detect constructed class/object types from
    tcallnode.gen_vmt_tree into its own method to avoid clutter
  * detect x.classtype.create constructs (with classtype = the
    system.tobject.classtype method), and treat them as if a
    "class of x" has been instantiated rather than a
    "class of tobject". this required storing the instantiated
    classrefs in their own array though, because at such a
    point we don't have a "class of x" tdef available (so
    now "x", and all other defs instantiated via a classref,
    are now stored as tobjectdefs in a separate array)

  + -Owoptvmts whole program optimisation which replaces vmt entries
    with method names of child classes in case the current class'
    method can never be called (e.g., because this class is never
    instantiated). As a result, such methods can then be removed
    by dead code removal/smart linking (not much effect for either
    the compiler, lazarus or a trivial lazarus app though).

  + symbol liveness wpo information extracted from smartlinked programs
    (-OW/-Owsymbolliveness)
  + use symbol liveness information to improve devirtualisation (don't
    consider classes created in code that has been dead code stripped).
    This requires at least two passes of using wpo (first uses dead code
    info to locate classes that are constructed only in dead code,
    second pass uses this info to potentially further devirtualise).
    I.e.:
     1) generate initial liveness and devirtualisation feedback
       fpc -FWtt.wpo -OWall tt.pp -Xs- -CX -XX
     2) use previously generated feedback, and regenerate new feedback
        based on this (i.e., disregard classes created in dead code)
       fpc -FWtt-1.wpo -OWall -Fwtt.wo -Owall tt.pp -Xs- -CX -XX
     3) use the newly generated feedback (in theory, it is possible
        that even more opportunities pop up afterwards; you can
        continue until the program does not get smaller anymore)
       fpc -Fwtt-1.wpo -Owall tt.pp -CX -XX
  * changed all message() to cgmessage() calls so the set codegenerror
  * changed static fsectionhandlers field to a regular field called
    fwpocomponents
  * changed registration of wpocomponents: no longer happens in the
    initialization section of their unit, but in the InitWpo routine
    (which has been moved from the woinfo to the wpo unit). This way
    you can register different classes based on the target/parameters.
  + added static method to twpocomponentbase for checking whether
    the command line parameters don't conflict with the requested
    optimisations (e.g. generating liveness info requires that
    smartlinking is turned on)
  + added static method to twpocomponentbase to request the
    section name
