* cpukit/score/cpu/powerpc/rtems/new-exceptions/cpu.h,
cpukit/score/cpu/powerpc/rtems/score/cpu.h,
cpukit/score/cpu/powerpc/rtems/score/powerpc.h:
Removed all macro definitions which depended on
the compiler defining a PPC CPU-model dependent
symbol.
Macros which were not used by cpukit have been
moved to libcpu/powerpc/rtems/powerpc/powerpc.h.
* libnetworking/Makefile.am, libnetworking/libc/gethostnamadr.c,
libnetworking/libc/getservbyname.c,
libnetworking/libc/getservbyport.c: Add initial versions of
getservbyport_r(), gethostbyaddr_r(), and getservbyport_r(). At this
point they are just simple weappers for the version without the _r in
the name.
* sapi/include/confdefs.h: When you disabled newlib reentrancy, it
still reserved memory for the reentrancy structure. This is about 1K
per task. On psim, we now reserve only 1936 bytes and only 240 remain
after all allocations. Further analysis will be required to narrow
that down. In addition, the new constant CONFIGURE_CONFDEFS_DEBUG can
be defined and the structure named Configuration_Memory_Debug will be
instantiated. This structure contains many of the component values
that go into the memory reservation computation. This is helpful when
tracking down problems.
* sapi/include/confdefs.h: The math in the _Configure_Object_RAM macro
was always adding heap overhead even when the number of objects
configured was zero and we would not do an allocation. This resulted
in an over estimation of the amount of Workspace required (~2K on
minimum.exe on PowerPC).
* cpukit/sapi/include/confdefs.h: Add missing quote to string to
remove warning.
* cpukit/score/cpu/m68k/rtems/score/m68k.h: Add the default
priority level for large memory Coldfires.
* posix/include/rtems/posix/pthread.h, posix/src/pthread.c,
posix/src/pthreadcreate.c, rtems/include/rtems.h, rtems/src/attr.c,
sapi/include/confdefs.h, sapi/include/rtems/config.h,
score/inline/rtems/score/stack.inl, score/src/isr.c,
score/src/mpci.c, score/src/threadcreateidle.c,
score/src/threadinitialize.c, score/src/threadstackallocate.c: Add
ability for application to configure minimum stack size. Add
RTEMS_CONFIGURED_MINIMUM_STACK_SIZE constant so user can clearly
indicate they want the configured as opposed to the recommended
minimum stack size.
* cpu_asm.S: Add Coldfire FPU support.
* rtems/score/m68k.h: Change the Coldfire CPU defines to be based
on the instruction set. Add Tiny RTEMS support to the small memory
model RTEMS processors.
* rtems/score/cpu.h: Handle the new Tiny RTEMS support.
* libcsupport/src/__times.c, libmisc/cpuuse/cpuusagereport.c,
libmisc/cpuuse/cpuusagereset.c, libmisc/monitor/mon-task.c,
rtems/include/rtems/rtems/ratemon.h, rtems/src/ratemongetstatus.c,
rtems/src/ratemonperiod.c, score/include/rtems/score/thread.h,
score/src/threaddispatch.c, score/src/threadinitialize.c,
score/src/threadtickletimeslice.c: Add typedefs for cpu usage and
period timing statistics. Also renamed related variables and
structure members so they are the same whether you are using
nanosecond (e.g. struct timespec) or ticks (e.g. uint32_t)
granularity. This lays the groundwork for future cleanup.
* sapi/include/confdefs.h: Rework to be more accurate on allocation. In
particular, there was a report from that Matthew Riek that memory was
being reserved twice for the IDLE task. This was covering up other
places that under allocated memory. Before I was done, I had reworked
the file to be easier to read, maintain and be more accurate.
* posix/src/psignal.c: Do not allocate any memory for queued signals if
the configuration parameter is 0. Before we would end up with an
allocation of 0 which rounded up and wasted some memory when POSIX
was configured.
