one tree builds

[Joel Sherrill <joel at OARcorp dot com>]

Hi,

I am in the process of trying to test 971122 and finding that this
snapshot has broken something in the one tree build procedure since the
970901 snapshot I last grabbed and successfully built.  The problem
appears to be that when libgcc1 is built, the cross gas is not found by
xgcc.  This happened on both sparc-rtems and m68k-rtems targets so I think
it is  a general build issue.  Here is the error message form the m68k
build:

cp ../../src/gcc/config/m68k/lb1sf68.asm libgcc1.S
for name in _mulsi3 _udivsi3 _divsi3 _umodsi3 _modsi3 _double _float
_floatex _eqdf2 _nedf2 _gtdf2 _gedf2 _ltdf2 _ledf2 _eqsf2 _nesf2 _gtsf2
_gesf2 _ltsf2 _lesf2; \
do \
  echo ${name}; \

  if [ $? -eq 0 ] ; then true; else exit 1; fi; \
  mv libgcc1.o ${name}.o; \
  /usr1/rtems/work/tools/build-m68k-tools/binutils/ar rc tmplibgcc1.a
${name}.o; \
  rm -f ${name}.o; \
done
_mulsi3
as: unrecognized option `-c68020'

I realize that the one-tree shell script from gcc 2.7.x will not work
since the gcc reorganization.  I am using a script which ends up doing
this:

rm -rf src
mkdir src
cd src

# EGCS has the latest configure scripts
for f in ../${GCC}/*
do
        ln -s $f .
done

for f in bfd binutils gas gprof ld opcodes
do
        ln -s ../${BINUTILS}/$f .
done

ln -s ../${NEWLIB}/newlib .

Does anyone have any ideas?  I was trying to make a test sweep through all
the rtems configurations before the egcs release.

Thanks.
