3.1 branch Ada cross report

[Joel Sherrill <joel dot sherrill at OARcorp dot com>]

Hi,

I finally got enough targets working for C and C++ that I 
thought I would invest some time in trying gnat.  On the 
old gcc 2.8.1 based GNAT, I was only able to build 
sparc-rtems and powerpc-rtems due to the more limited
support for embedded targets and ELF for them.

My native compiler is the ACT 3.14p binary from cs.nyu.edu.
newlib is CVS, gcc is 3.1 CVS last updated Saturday
about 10am CDT.

I should also thank Laurent Guerby for helping me fight some
basic build problems.  I have some RTEMS specific Ada 
patches and a general cross Ada one from Laurent in my
tree.

Some general impressions:

  + i386-rtems fails to build with a GNAT BUG BOX. :(
    Makes me wonder how native x86 versions are doing.
  + at least hppa1.1 assumes native build for CFLAGS
  + general include PATH problem which is manifested
    as inability to find newlib's .h files and at least
    in one case the file config/mips/ecoff.h.  This 
    seems to explain arm, powerpc, mips, and mips64orion.
  + Some target CPUs do not have the Ada exception support.
    h8300, m68k, and sh targets failed for this reason.

sparc-rtems - This is the ONLY target that built OK.  I am 
   going to run ACATS on it.

arm-rtems - adaint.c fails with these
	adaint.h:100: parse error before '*' token
	I don't see anything wrong at that line.  :(

h8300-rtems - 
	raise.c: In function `__gnat_eh_personality':
	raise.c:601: built-in function `__builtin_eh_return_data_regno' not
currently supported

hppa1.1-rtems -
	gcc -c -g -O2  -mdisable-indexing -W -Wall -gnatpg -gnata -I- -I.
-I../../../gcc-to-merge/gcc/ada ../../../gcc-to-merge/gcc/ada/ada.ads
gnat1: Invalid option `disable-indexing'
	Apparently the configure scripts assume an hpux compiler?

i386-rtems - GNAT BUG box (says gnatpro)

mips64orion-rtems and mips-rtems - appears to be a Makefile problem
	make[2]: *** No rule to make target
`../../../gcc-to-merge/gcc/ada/config/mips/ecoff.h', needed by
`final.o'.  Stop.


powerpc-rtems - can't find C library includes possibly because it
	isn't properly handling -enable-newlib?
