7d8d0340b9 Merged revision(s) 31988, 31991-31993, 32136, 32308-32309, 32312, 32318 from branches/svenbarth/packages:
Correctly parse the directives DenyPackageUnit and WeakPackageUnit

ppu.pas:
  + add flags uf_packagedeny and uf_packageweak
scandir.pas:
  + new procedure do_moduleflagswitch() which parses a ON/OFF/+/- argument and sets or clears a flag in the current module
  + new procedure dir_denypackageunit which handles DenyPackageUnit
  * implement dir_weakpackageunit (and move to the correct location ;) )
  * InitScannerDirectives: add dir_denypackageunit handler
........
Respect DenyPackageUnit flag.

pmodules.pas, proc_package:
  * check all contained units that are not already part of a package for their uf_package_deny flag and report an error for each that has it set
........
Do not check whether all units are used as by definition all units of a package are considered as used.

pmodules.pas, proc_package:
  - remove call to current_module.allunitsused
........
Check whether a unit has been implicitely imported in a package. A unit is considered as implicitely imported if it is not part of a required package nor part of the units listed in the contains section. This note is useful (Delphi even provides a dialog in that case) as a package with implicitely imported units /might/ become incompatible with other packages (e.g. if another package includes that unit uses that package and includes that unit explicitely; of course that is the same as if both package included it explicitely, but with the hint one knows where to look).

pmodules.pas, proc_package:
  * while walking the loaded units also check whether any of them not contained in a package was part of the contained units which are the same as the current module's used units
........
Generate CRC for package files

pcp.pas, tpcpfile:
  + new field do_crc which controls CRC generation
  + override putdata() method to generate CRC when data is written
  * resetfile: enable do_crc by default
........fppu.pas, tppumodule:
  * loadfrompackage: mention if a unit is loaded from a package
........
fpkg.pas, tcontainedunit:
  + new fields offset and size for the PPU data stored inside the PCP
fpcp.pas, tpcppackage:
  * readcontainedunits & addunit: correctly initialize offset and size to 0
........
Store the modified PPU files directly inside the PCP and thus get finally rid of the .ppl.ppu files.

entfile.pas:
  + new entry type ibpputable
pkgutil.pas:
  * adjust RewritePPU to work on a stream as output instead of a filename
fpcp.pas, tpcppackage:
  + new method writepputable() which writes the offsets and sizes of all contained units (not part of CRC!)
  + new method writeppudata() which rewrites all contained PPUs directly into the PCP after the ibend entry (Note: the data is written 16 Byte aligned to ease viewing of the PCP and its contained PPUs in a hex editor)
  + new method readpputable() which reads the offsets and sizes of all contained units
  + new method getmodulestream() which returns a substream for a contained module
  * loadpcp: also call readpputable()
  * writepcp: first write an empty pputable, then finish writing all data that requires the put*/write* methods of the pcpfile, then use writeppudata() to write all PPUs and finally write the correct pputable at the original location
fppu.pas, tppumodule:
  * loadfrompackage: don't read the PPU from a file if it is contained in a package, but using the new tpcppackage.getmodulestream() and tppumodule.openppustream() methods
pmodules.pas, proc_package:
  * don't rewrite the PPUs here
pcp.pas:
  * increase CurrentPCPVersion
........
Fix cycling

c5bdc11cb2 Merged revision(s) 31924, 31934-31937 from branches/svenbarth/packages:
pmodules.pas, proc_package:
  * generate the dummy entry symbol only on Windows systems (ToDo for other systems that might need it)

........
options.pas:
  * TOption.interpret_option & read_arguments: use add_package() from pkgutils instead of addpackage() from fpkg
fpkg.pas:
  - remove no longer needed addpackage()

........
pkgutil.pas:
  + new procedure add_package_libs() to add all packages as libraries that are also linked against
pmodules.pas:
  * proc_package & proc_program: add all package libraries to the linker before creating the final binary

........
pkgutil.pas, add_package:
  * package names are case insensitive so add them in uppercase to correctly detect duplicates

........
Keep track of how many units are used from each required/requested package and only link those from which any units are used.

fpkg.pas, tpackageentry:
  + new field usedunits to count how many units of the package are used
pkgutil.pas:
  + new procedure add_package_unit_ref() to increase the amount of used units for the given package
pmodules.pas:
  * proc_package & proc_program: check which units of all loaded ones are provided by other packages

f55123ce92 Merged revision(s) 28904-28905, 29038-29044 from branches/svenbarth/packages:
Don't try to export generic symbols.

pkgutil.pas:
  * exportabstractrecordsymproc: do not export generic type symbols or their nested symbols
........
Ensure that the correct name is used for the PCP file.

proc_package:
  * use current_module.modulename instead of module_name for the base filename of the PCP file
........
Add a possibility to track if a unit was loaded from a package.

fmodule.pas, tmodule:
  + new field "package" which is Nil if the unit is not (yet) part of a package or a reference to the package this unit was loaded from
fppu.pas, tppumodule:
  * loadfrompackage: set the "package" field of the module to the package it's loaded from.

........
Ensure that units loaded from a package are not recompiled if the source files should happen to be available.

fppu.pas, tppumodule:
  loadppu: set the state to ms_compiled instead of ms_load if the unit was loaded from a package (additionally close the PPU file as it's no longer needed)

........
Add support for reading/writing required packages from/to the PCP file

fpcp.pas, tpcppackage:
  + new methods writerequiredpackages and readrequiredpackages
  * loadpcp: use readrequiredpackages
  * savepcp: use writerequiredpackages
pcp.pas:
  * increase PCP version

........
When compiling a package, handle only those units that are not yet part of a package.

pmodules.pas, proc_package:
  * only export units that are part of the package
  * only add units to the package if they are really part of the package
  * don't rewrite the PPU if the unit is not part of the package
  * don't link the unit's files if it is not part of the package

........
Add support for parsing required packages.

pkgutil.pas:
  + new function add_package to add a package to the list of available packages with the possibility to check for duplicates
  * load_packages: also load all required packages
pmodules.pas, proc_package:
  * create the tpcppackage instance earlier (and use the module name as read from the source file as package name)
  * clear the list of packages in case the user passed any using -FPxxx
  * parse the "requires" section like a list of units and add each full identifier as a package to load
  * before parsing the "contains" section load all packages, so that all units can be correctly resolved

........
Correctly create import libraries for packages as well.

pkgutil.pas, createimportlibfromexternals:
  * instead of processing units without the uf_in_library flag, only process those that don't have a package reference set (thus becoming part of the program/library or the package)
  - remove unneeded "pkg" parameter
pmodules.pas:
  + proc_package: create the import library if the package requires other packages
  * proc_program: adjust call to createimportlibfromexternals

........
Ensure that the reference to the System unit is correctly set up for packages. Among other things this is needed to compile a package with the -gl option (though debug information doesn't work yet).

pmodules.pas:
  * convert AddUnit to a function and let it return the newly loaded module
  * proc_package: when parsing the contained units ensure that we correctly set up the System unit reference if we are to contain the System unit
  * proc_package: also set up the System unit reference once all units are loaded and this hasn't happened yet (because all contained units are already compiled)

9d1938a713 Partial merge of r28851 (aside the parts that requires the global assembler symbols)
Generate the import library for each used package.

pkgutil.pas:
  - remove function createimportlibfromexports
  + new function createimportlibfromexternals which uses the imported unit symbols of a unit to generate the correct import library for each used package used in a program or library
pmodules.pas, proc_program:
  * move the generation of the import library further down until all tables were generated of which entries might reside in a package
  * use createimportlibfromexternals to generate the import library for the program/library

globals.pas:
  + new variable "packagesearchpath" which contains all paths in which package files should be looked for
  + new variable "packagelist" which contains a list of all packages that should be used in a program or library
  * InitGlobals & DoneGlobals: initialize/finalize "packagesearchpath" accordingly ("packagelist" is handled in unit fpkg using a init/done-callback)
options.pas:
  + TOption: new fields "parapackagepath" and "parapackages" to keep track of package search paths and package files passed as parameters
  * TOption.interpret_option: use '-Fp' for package search paths and '-FP' for package files
  * read_arguments: apply the passed package search paths and packages to their respective containers
........
+ add a new unit which will contain basic functions related to handling packages
........
Move package related functions from pmodules to pkgutil.

pmodules.pas => pkgutil.pas:
  * createimportlibfromexports
  * varexport
  * procexport
  * insert_export

pkgutil.pas:
  + new function export_unit
  - remove exports of procexport, varexport and insert_export

Some small fixes for package parsing.

pmodules.pas, proc_package:
  * use orgpattern instead of pattern to build the module name (like is done in uses sections)
  * ignore duplicates when generating exports
  - no need to generate an import library for the package; that is done by the program/library that uses the package
........
+ new unit fpcp of which the class tpcppackage handles the reading and writing of package metadata from/to pcp files (equivalant to tppumodule).
........
+ add unit which contains representation of a PCP file (tpcpfile) like tppufile is for units.

  + new function exportprocsym to correctly export a procedure with all its aliases
  + new function exportabstractrecordsymproc to export the members of structured types 
  * insert_export: handle also namespacesym and propertsym (by ignoring them)
  * insert_export: correctly export classes, record and objects
  * insert_export: use new exportprocsym function to export a procsym
  * insert_export: only export public variables of a static symtable

........
* use messages to get rid of most writelns related to package loading
........
Add additional entry types for PCP files

entfile.pas:

........
Generate the PCP file once the package file and the used units were compiled correctly.

pmodules.pas:
  * proc_package: generate the PCP file upon successful compilation
........
Add the possibility to load all packages supplied as parameters.

pkgutil.pas:
  + new function load_packages to load all packages supplied as parameters
pmodules.pas, proc_program:
  * use load_packages to load all packages before any unit is loaded
........
Add code which tries to load a unit from a package first and only then as usual.

fppu.pas, tppumodule:
  + new method loadfrompackage which searches all available packages for the unit and loads it from there if found
  * loadppu: first try to load the unit from a package if any are available
........
Don't link objects files of a unit that is provided by a package.

pmodules.pas, proc_program:
  * if a unit has uf_in_library set we must not include it in the units we link against

  * if the initialization or finalization procedure is empty also remove their assembler symbols so they are exported
........
Ensure that readonly sections that need relocations are indeed declared as such.
Thanks to Jonas for this.

ncgvmt.pas, TVMTWriter:

84c33631ef * Have the sysinit unit, if any, passed to the linker first (currently it is passed last). This is necessary to get the same linking order on targets with assembler startup and with Pascal startup. In particular, it allows to define global symbols like "data_start" in sysinit unit and expect that they will actually end up before other data in executable.

fa3b0ca312 * support marking defs created via the getreusable*() class methods as
"don't free even if not registered"; use for defs that may not be written
    to a ppu file, but that must nevertheless survive the compilation of the
    current module
  * mark all defs created for para locations as "don't free even if not
    registered", because we don't discard and recalculate all para locations
    after a module has been compiled (since that's not needed)
   o solves issues if the paralocations for a routine in the interface of

bd09b88a5b + support for http://en.wikipedia.org/wiki/Blocks_(C_language_extension)
o blocks are implemented as a variation of procedure variables
   o declaration of a block variable: "test: procedure(c: char) is block;"
     (C equivalent: (void)(^test)(char c) )
   o the compiler automatically converts procedures/functions whose address
     is passed to a block parameter or assigned to a block variable into
     a "block". This consists of
    1) generating a block descriptor (containing the size of the "block
       literal" (see below) and the signature of the invocation function
       encoded as an Objective-C selector)
    2) generating a wrapper function around the original funcion (with C
       calling convention), that has an extra first hidden parameter
       (marked as vo_is_parentfp in the compiler) whose type is a pointer
       to the describing "block literal"
    3) generating the "block literal", which contains a pointer to an
       external variable indicating whether this block captures context or
       not, some flags (see compiler/blockutl.get_block_literal_flags for
       info), a pointer to the wrapper function and a pointer to the
       descriptor. In the future, it will also contain captured variables.
   o right now, only global procedures/functions can be converted to blocks
     (because they don't require state capturing). The next steps are (Object
     Pascal) methods (not Objective-C methods, because Objective-C method
     procvars don't exist) and finally nested functions
   o on Mac OS X, the functionality will only work on Mac OS X 10.7 and later,
     because we have to use the so-called "ABI.2010.3.16" to ensure that
     our blocks aren't called as variadic functions by the runtime (which
     came out after the Mac OS X 10.6 release)
   o while the currently implemented functionality does not require any
     library support at all, there's no use enabling it on other platforms
     because unless it has been confirmed to work with a blocks runtime,
     there's no point in using blocks (they're just somewhat bulky procvars
     right now). Enabling it on other platforms (in combination with the
     GNUStep Objective-C run time), should simply be a matter of adding
     the right {$linklib xxx} statement to rtl/inc/blockrtl.pp file, adding
     that file to Makefile.fpc for that platform and adding that platform
     to the compiler/systems.systems_blocks_supported set

b57c95043f + support overriding tdef/tsym methods with target-specific functionality:
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type

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

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

979f55e1db + support for procedural variables for the JVM target
o every porocedural variable type is represented by a class with one
     public "invoke" method whose signature matches the signature of the
     procvar
   o internally, dispatching happens via java.lang.reflect.Method.invoke().
     WARNING: while this allows calling private/protected or other methods
     that are normally not accessible from another context, a security
     manger can override this. If such a security manager is installed,
     most procvars will cause security exceptions
   o such dispatching also requires that all arguments are wrapped, but
     that's done in the compiler-generated body of the invoke method,
     so that procvars can also be called conveniently from Java code
   o typecasting between a procedure of object and tmethod is supported,
     as well as Delphi-style replacing of only the method pointer via
     @procvar1=@procvar2.
   o nested procvars are not yet supported, but most of the basic
     infrastructure for them is already present
  * all units/programs now get an internal __FPC_JVM_Module_Class_Alias$
    type when compiled for the JVM target, which is an "external" class
    that maps to the unit name. This is required to look up the
    JLRMethod instances for regular functions/procedures

6165536b5e + added {$modeswitch objectivec1}/-Mobjectivec1 mode switch to enable
the use of Objective-C 1.0 constructs. Because it is a mode switch, it
    can be used cumulatively with every syntax mode. Note that a {$mode xxx}
    statement resets all mode switches as well, so you cannot use the
    -Mobjectivec1 variant if you have such a statement in a unit. This
    modeswitch is currently only enabled for Darwin/PowerPC and Darwin/i386,
    as the backend support is not yet implemented for other platforms.
  + implemented selector() statement that can be used to create an Objective-C
    selector for the message with the specified *constant* name (in the future,
    it will also work for Objective-C method identifiers)
  + added SEL type to the system unit (the selector() statement returns it)
  + added all Objective-C segments to the assembler writers

    {$modeswitch objectivec1} statement is used

  + 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
     b) use it to optimise the program
      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
      program (or with a changed version of the same program)

  * 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,

    with method names of child classes in case the current class'
    method can never be called (e.g., because this class is never

  + 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

libraries on linux (mantis #6822)
  * fixed execution of library finalization sections on darwin

     compilation unit itself was executed, now those of the units
     used by the library are also executed)

f36e5411af * split cpu64bit compiler define into
a) cpu64bitaddr, which means that we are generating a compiler which
       will generate code for targets with a 64 bit address space/abi
    b) cpu64bitalu, which means that we are generating a compiler which
       will generate code for a cpu with support for 64 bit integer
       operations (possibly running in a 32 bit address space, depending
       on the cpu64bitaddr define)
   All cpus which had cpu64bit set now have both the above defines set,
   and none of the 32 bit cpus have cpu64bitalu set (and none will
   compile with it currently)
  + pint and puint types, similar to aint/aword (not pword because that
    that conflicts with pword=^word)
  * several changes from aint/aword to pint/pword
  * some changes of tcgsize2size[OS_INT] to sizeof(pint)

2b84a4643a * Fixed bug #6501: multiple resource files are correctly linked to executable.
It is done in the following way:

When unit is compiled, .rc file are compiled to .res and list of unit's resource files is stored in .ppu
Before final linking all program's .res files are collected into global .res file (.res files are easily concatenated). 
Then this global .res files is compiled to single .or file, which is linked to executable. 
As a result global resource index is created and the problem is fixed.

Old resource processing behavior still supported when tresinfo.rcbin is not set for target.
New resource processing is activated for windows and linux. Cross compiled windres can be used to compile .rc files on linux.
