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 :/ )
git-svn-id: trunk@33949 -
systems.pas:
+ add new constant systems_indirect_var_imports to denote all targets that /require/ indirect references for cross-unit variables accesses
git-svn-id: trunk@33284 -
Add a new target flag which determines whether the target supports dynamic packages or not.
systems.pas:
+ new flag tf_supports_packages
pmodules.pas, proc_package:
* error out when flag tf_supports_packages is not set for the current target
msg/errore.msg:
+ error message for when tf_supports_packages is missing and a package file is compiled

caller side, as this is an AArch64 ABI requirement (unrelated to Darwin).
Fixes webtbs/tw3523 compiled with optimisations on Linux/AArch64

for all non-ppc(32/64) Darwin platforms
o pass the macosx-version-min/iphoneos-version-min to clang as an assembler,
so that it properly sets this information starting with Xcode 7 (solves
errors when targeting the iOS simulator, and warnings about object files
being compiled for a different OS X version when targeting (Mac) OS X)
o the old assembler is still selectable via -Aas-darwin (required with
Xcode 3.1.x and older)
o since the first Xcode version that shipped with Clang is Xcode 3.2, which
is available for Mac OS X 10.6, most users should not encounter any issues
with the new default (in fact, it fixes some tests for x86 because Clang
supports some instructions that "as" doesn't). Clang does not support
Stabs however, so -gs does require the use of -Aas-darwin

library. This resolves a problem with parallel building of a i8086 cross
compiler, due to a race condition in wlib, when running several instances of
wlib in the same directory. The problem is in the way wlib creates a temp file
in the current directory using non-atomic operations and with a high
probability of a name collision. Using separate input and output files avoids
this temp file creation by wlib.

as the AIX abi (especially on ppc64)
o replaced (for now) all checks for the AIX abi with a check for either the
AIX or Darwin abi
o changed the ABI of Darwin/ppc, Darwin/ppc64 and Mac OS/ppc to
abi_powerpc_darwin
