are the same in case of open arrays (their size can't be determined at
compile time) -- this is just a sanity check, which can't be performed in
this case

Move PascalMain external from the si_*.inc files to a new include file si_impl.inc that's included in the implementation sections of the si_*.pp units
git-svn-id: trunk@33970 -
* always register implementation-only, public routines as they might only be called from other units using an external declaration
git-svn-id: trunk@33967 -
* only export the symbol name with the indirect suffix (on Windows the indirect ones will be generated in the module that does the importing on other system's they're not needed anyway)
git-svn-id: trunk@33966 -
compiler/utils/ppuutils/ppudump, readdefinitions:
* with the move of most target specific PPU data into the target specific sym types the location of the library symbol for the Amiga-like systems has changed
git-svn-id: trunk@33965 -
rtl/inc/system.inc:
+ ResHeader variable that provides the public _FPC_ResLocation symbol used by intres.inc; this variable will always be available and without indirect entry information it will simply hook up to FPC_RESLOCATION itself
* SetupEntryInformation: setup FPCResLocation
rtl/inc/intres.inc:
* no need to cater for indirect entry or not anymore
git-svn-id: trunk@33964 -
* FPC_HAS_DYNAMIC_PACKAGES is set if the target does support dynamic packages (currently none, but soon(TM) that should be i386-win32, {i386,x86_64}-linux and all darwin systems)
* FPC_HAS_INDIRECT_VAR_ACCESS is set if assembler code should assume that variables from another unit are accessed indirectly (thus different assembler code should be used)

Adjust non-Windows resources to work with indirect main information as well.
rtl/inc/systemh.inc, TEntryInformation:
+ new cross platform field ResLocation which stores the pointer to the resources
rtl/inc/intres.inc:
* change the type of ResHeader from PResHdr to PPResHdr (and adjust code that uses it accordingly; Note: the first dereferencing is assumed to be always valid!)
* adjust declaration of ResHeader depending on whether indirect main information is used or not
rtl/darwin/sysinit.pas & rtl/linux/si_impl.inc:
* pass the location of the resources through SysInitEntryInformation
rtl/bsd/system.pp & rtl/linux/system.pp:
+ new public variable FPCResLocation which is setup by SysEntry
rtl/win32/sysinit.inc:
* initialize ResLocation of SysInitEntryInformation as Nil
rtl/win32/system.pp:
* initialize ResLocation of EntryInformation as Nil
........
For systems that support both internal and external resources (in this case only Darwin ones) we need to generate the FPC_RESLOCATION symbol always, because the SysInit unit is resource type agnostic.
ngenutil.pas, tnodeutils:
* InsertResourceInfo: generate FPC_RESLOCATION symbol pointing to 0 in case the program is compiled on Darwin with resources set to external ones (-We)

Switch Mac OS X to indirect entry information.
compiler/systems/t_bsd.pas, TLinkerBSD:
+ implement InitSysInitUnitName
compiler/system.pas:
* systems_internal_sysinit: add Darwin systems
compiler/hlcgobj.pas, thlcgobj:
* gen_proc_symbol_end: for Darwin systems don't directly call PascalMain for libraries, but FPC_LIBMAIN instead
rtl/darwin:
+ add sysinit.pas unit which contains the executable and library entry points for Darwin
rtl/darwin/Makefile.fpc:
* add sysinit unit
rtl/bsd/sysosh.inc:
+ add a Darwin specific TPlatformEntryInformation (could probably be used for all Unix systems...)
rtl/bsd/system.pp:
* define FPC_HAS_INDIRECT_MAIN_INFORMATION for Darwin systems once we're no longer bootstrapping with 2.6.x
+ add EntryInformation variable (this could maybe moved to system.inc...)
+ add new procedure SysEntry that is called from the entrypoint and which sets up necessary information required by other parts of the RTL
* the old FPC_SYSTEMMAIN is still in place for bootstrapping
rtl/inc/systemh.inc, TEntryInformation:
* PascalMain is cdecl on non-Windows systems (ToDo: really?)
rtl/inc/system.inc:
* initialstklen is provided by the indirect entry information, so no external here
........
Fix bootstrapping.
rtl/darwin/sysinit.pas:
* enable the code only when no longer bootstrapping with 2.6.x
........
Fix bootstrapping.
rtl/objpas/objpas.pp:
* define FPC_HAS_INDIRECT_MAIN_INFORMATION for Darwin only while not bootstrapping with 2.6.x
........
rtl/darwin/sysinit.pas:
* reference PASCALMAIN correctly (I wonder how this even worked previously :/ )

normally returns int64 in FPC), before performing any further calculations -
the result always fits in a longint (the date is range checked against
MaxDateTime and that is well within longint limits). This generates faster
code on non 64-bit targets and also fixes i8086 compilation, which previously
failed on register allocation on this function.

Merged revision(s) 28239-28289 from branches/svenbarth/packages:
Provide the possiblity to switch between the direct and indirect RTTI symbols.
ncgrtti.pas, TRTTIWriter:
+ get_rtti_label, get_rtti_label_ord2str & get_rtti_label_str2ord: add new "indirect" parameter and pass that along to rtti_mangledname
hlcgobj.pas, thlcgobj:
* g_incrrefcount, g_initialize, g_finalize, g_array_rtti_helper: for now pass along False to get_rtti_label()
ncgvmt.pas, TVMTWriter:
* writevmt: for now pass along False to get_rtti_label()
ncgld.pas, tcgrttinode:
* pass_generate_code: for now pass along False to the get_rtti_label*() methods
........
Provide possibility to select between using a direct and an indirect RTTI reference. This way the references can be changed for selected cases.
ncgrtti, TRTTIWriter:
* ref_rtti: new "indirect" parameter that's relayed to rtti_mangledname()
* write_rtti_reference: new "indirect" paramater that's relayed to ref_rtti()
........
Switch properties to use the indirect type information without breaking backwards compatiblity. :)
compiler/ncgrtti.pas, TRTTIWriter:
* published_properties_write_rtti_data: use the indirect reference, not the direct one
rtl/objpas/typinfo.pp:
* to allow compilation with both 2.6.x and 2.7.1 and too avoid too many ifdefs at least in the declarations we define a macro TypeInfoPtr which is either PTypeInfo (2.6.x) or PPTypeInfo (2.7.1 and newer)
* TPropInfo: rename PropType to PropTypeRef and change type to TypeInfoPtr
+ TPropInfo: add a new property PropType which returns a PTypeInfo out of the PropTypeRef depending on the compiler version
........
Switch further simple types (sets, enums, class references, pointers) to indirect type information (again without breaking backwards compatibility).
compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data:
* enumdef_rtti, setdef_rtti, classrefdef_rtti & pointerdef_rtti: write an indirect RTTI reference
rtl/objpas/typinfo.pp, TTypeData:
* rename BaseType to BaseTypeRef, CompType to CompTypeRef, InstanceType to InstanceTypeRef and RefType to RefTypeRef and change their type to TypeInfoPtr
+ add properties BaseType, CompType, InstanceType & RefType which return a PTypeInfo out of the corresponding *Ref field depending on the compiler version
........
Switch class and interface parent as well as extended type to indirect type information
compiler/ncgrtti.pas, TRTTIWriter:
* write_rtti_data.objectdef_rtti.objectdef_rtti_class_full: use indirect reference for class parent and extended type
* write_rtti_data.objectdef_rtti.objectdef_rtti_interface_full: use indirect reference for interface parent
rtl/objpas/typinfo.pp, TTypeData:
+ add new method DerefTypeInfoPtr which returns Nil if the indirect reference is Nil and otherwise returns the dereferences indirect reference (for 2.6.x the direct reference is returned as is)
* rename ParentInfo to ParentInfoRef, HelperParent to HelperParentRef, ExtendedInfo to ExtendedInfoRef, IntfParent ot IntfParentRef and RawIntfParent to RawIntfParentRef and change their type to TypeInfoPtr
+ introduce ParentInfo, HelperParent, ExtendedInfo, IntfParent and RawIntfParent properties that return a PTypeInfo and use the new DerefTypeInfoPtr to return the correct type info value
* change the other newly introduced properties of TTypeData to use DerefTypeInfoPtr as well to be on the safe side
........
Switch record/object fields to indirect type information references.
compiler/ncgrtti.pas, TRTTIWriter.fields_write_rtti_data:
* use the indirect reference for the object parent type
* use the indirect reference for the field type
rtl/inc/rtti.inc:
* TRecordElement: change TypeInfo to PPointer for 2.7.1 and newer
* RecordRTTI: correctly dereference the element type for 2.7.1 and newer
* fpc_copy: correctly reference the element type for 2.7.1 and newer
........
Switch static arrays to indirect RTTI reference.
compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data:
* arraydef_rtti: write the dimension types and the final field type as indirect references
rtl/inc/rtti.inc:
* TArrayInfo: switch ElInfo to PPointer for 2.7.1+
* ArrayRTTI & fpc_copy: correctly dereference ElInfo for 2.7.1+
rtl/objpas/typinfo.pp, TArrayTypeData:
* switch ElType and Dims to PPTypeInfo; no backwards compatibility needed here as TArrayTypeData was added in 2.7.1 only
tests/test/trtti8.pp: fix test
........
Switch dynamic arrays to indirect RTTI references.
compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data.arraydef_rtti:
* write indirect references for the two element entries
rtl/inc/dynarr.inc:
* tdynarraytypedata: change elType2 to PPointer for 2.7.1+
* fpc_dynarray_clear, fpc_dynarray_setlength & fpc_dynarray_copy: correctly dereference elType2 for 2.7.1+
rtl/objpas/typinfo.pp, TTypeData:
* rename elType and elType2 to elTypeRef and elType2Ref respectively and change type to TypeInfoPtr
* add properties elType and elType2 which return PTypeInfo by dereferencing elTypeRef and elType2Ref respecively correctly
* remove a few stray "inline" directives in the implementation
........
Switch procedure parameters and result type to indirect RTTI references.
compiler/ncgrtti.pas, TRTTIWriter.write_rtti_data.procvardef_rtti:
* write_procedure_param: use indirect RTTI reference
* write result info for both methods and procvars as indirect RTTI reference

* TTypeData: remark in the comments of tkMethod that ResultTypeRef and ParamTypeRefs are of type PPTypeInfo and not PTypeInfo
tests/test/trtti9.pp:
* fix test
........
Remove no longer needed "indirect" parameter for TRTTIWriter methods.
ncgrtti.pas, TRTTIWriter:
- ref_rtti & write_rtti_reference: remove "indirect" parameter
* ref_rtti: call rtti_mangledname with "indirect" always set to "true"
- remove "true" parameter on callsites of write_rtti_reference & ref_rtti
........

all of their values, when kept in a bitpacked array, properly via
pass_typecheck rather than hacking location.size in pass_generate_code:
o the old fix was incomplete (it didn't handle non-constant indices)
o the old fix didn't work for llvm (since it uses defs rather than
location.size)
