threadvar (and having to deal with differences between the ELFv1 and ELFv2
ABIs regarding indirect function calls, + future ability to have the
compiler generate PIC for those routines)
o includes workaround for lack of linkage area size allocation in current
released PPC64 versions, remove after 3.0.2 has been released

as that's the type of argc in the system unit (which maps onto this
variable), and even in C it's "int argc". This fixes the use of this
variable on big endian targets

Each port that allows the usage of dynamic libraries should call InitSystemDynLibs during initialization of the System unit.
The DynLibs unit has been adjusted to be a forwarder for the functions that now reside in the System unit (for backwards compatiblity just in case). Additionally the unit will register the DynLibsManager if it doesn't reside in the System unit anyway.
Currently only the Windows targets (Win32, Win64 and WinCE) implement the DynLibsManager inside the System unit. For other systems using the LoadLibrary, etc. functions will lead to a run error/exception.
If a port wants to implement its own DynLibsManager then it needs to define DISABLE_NO_DYNLIBS_MANAGER. TLibHandle, NilHandle and optionally TOrdinalEntry (it's set to SizeUInt otherwise) should be defined in sysdlh.inc which needs to be enabled using the define FPC_SYSTEM_HAS_SYSDLH (because there are targets which have FEATURE_DYNLIBS enabled, but don't support them... e.g. powerpc-wii -.-).
The DynLibsManager contains methods for loading a library based on a RawByteString and based on a UnicodeString. BOTH should be implemented, but internally one can forward to the other.
The loading by ordinal *can* be be implemented. If it is set to Nil then the implementation of GetProcAddress(lib,ordinal) will return Nil.
+ new functions SetDynLibsManager and GetDynLibsManager to set and retrieve the current DynLibsManager
* provide interface of DynLibs unit in unit System

rtl/linux/ostypes.inc:
* correctly define the _STAT_VER_* constants for x86_64 (the ifdefs are based on those in the C header; for other platforms this needs to be checked)
git-svn-id: trunk@29241 -
osmacro.inc:
* FpFstat, fpLstat and FpStat: correctly set the result value instead of relying on the result location being the same for cdecl functions as for register functions

* It fixes regression of tw16283b after r27169.
* BeOS, Haiku: added fpc_cpucodeinit to compensate for removal of SysInitFPU, it also enables use of CPU features like SSE.
git-svn-id: trunk@27171 -
* As a first part of cleanup, replaced StackTop with function returning StackBottom+StackLength.
* On Win32 and Win64, StackTop returns the stack base from TIB instead.

* rtl/linux/m68k/prt0.as:
between the arguments and the environment variables is a NULL; keep this in mind when loading the address of the first environment variable.
