PR 356/bsps
This patch makes RTEMS/powerpc/shared EABI compliant.
* irq/irq_init.c, start/Makefile.am, start/start.S, startup/bspstart.c,
startup/pgtbl_setup.c, vectors/vectors.h, vectors/vectors_init.c:
zero_bss() should clear not only bss but sbss and sbss2
also (this is probably a bugfix, as sbss/sbss2 are
probably used even if -msdata=eabi is not specified).
* start/rtems_crti.S: New file which must
be linked immediately after ecrti.o. rtems_crti.o contains
a code snippet who lets __init() return immediately. Also,
a new entry point '_init' to the C++ Ctors is generated
for use by the RTEMS Thread_Handler.
