* new-exceptions/bspsupport/ppc_exc_asm_macros.h,
new-exceptions/bspsupport/ppc_exc.S,
new-exceptions/bspsupport/README,
new-exceptions/bspsupport/ppc_exc_hdl.c:
Thomas Doerfler clarified (thanks!) that raising an
exception and executing the 1st instruction is not
an atomical operation. I added a fix to the code that
checks if a lower-priority interrupt is under way:
we now not only test if the 'lock' variable was set
but also check if the interrupted PC points to the
'write lock' instruction.
Added more comments and updated README.
* rtems.adb, rtems.ads: Refactored rtems_clock_get into 5 methods
which are single purpose and more strongly typed. They are:
rtems_clock_get_tod - Get TOD in Classic API structure
rtems_clock_get_tod_timeval - Get TOD in struct timeval
rtems_clock_get_seconds_since_epoch - Get TOD as seconds since 1988
rtems_clock_get_ticks_since_boot - Get ticks since boot
rtems_clock_get_ticks_per_second - Get ticks per second
Also switch from using 'Unchecked_Access to 'Access.
Added pragma Convention C as required by gcc > 4.3.
Changed style of parenthese on subprogram calls to match GNAT.
* start/start.S, startup/bspstart.c: disable memory-select
errors early (in start.S) to avoid hangs due to speculative
memory access (motload maps absent memory in TLBs).
Remove TLB mappings for which no physical memory is installed
(bspstart). Enable HID1[RFXE] so that 'core_fault_in' errors
result in a machine-check rather than stalling the machine.
Re-enable memory-select errors at this point.
* startup/linkcmds, startup/linkcmds-le, startup/linkcmds-le.coff: Add
wildcard to gcc_except_table section so programs compiled with gcc
4.3.x can link.
* startup/linkcmds, startup/linkcmds.hsc_cm01,
startup/linkcmds.mpc8349eamds: Add wildcard to gcc_except_table
section so programs compiled with gcc 4.3.x can link.
* startup/linkcmds, startup/linkcmds.brs5l, startup/linkcmds.icecube,
startup/linkcmds.pm520: Add wildcard to gcc_except_table section so
programs compiled with gcc 4.3.x can link.
* startup/linkcmds, startup/linkcmds.bootp, startup/linkcmds.prom: Add
wildcard to gcc_except_table section so programs compiled with gcc
4.3.x can link.
* configure.ac, sptests/Makefile.am: Exercise passing as object Id of
SELF.
* sptests/spname01/.cvsignore, sptests/spname01/Makefile.am,
sptests/spname01/ada_spname01.scn, sptests/spname01/spname01.adb,
sptests/spname01/sptest.adb, sptests/spname01/sptest.ads: New files.
