* Don't mess with FPU control word, libraries should leave it alone. * Don't call FPC_LIB_EXIT from haltproc, unit finalization is performed before haltproc. + non-executable stack marker. git-svn-id: trunk@26763 -

# FreeBSD standard (shared) ELF startup code for Free Pascal
|
|
#
|
|
# FreeBSD RunTime dynamic loader only
|
|
# calls the functions specified by -init
|
|
# as functions without parameters
|
|
# Thus, it is not possible to retrieve argc, argv and envp
|
|
# for libraries.
|
|
# On x86_64 CPU, using weak for the operatingsystem_parameter_XXX
|
|
# allows to bind to main program parameters,
|
|
# but this does not seem to work for i386 loader.
