Egcs-971114 cross compiler test result

[gyoung yun cho <gycho at dolphin dot pknu dot ac dot kr>]

I tested egcs snapshots on LINUX slackware 3.3 to make cross compiler.

My tool chain is :
============================================================================
/usr/local/src/binutils-2.8.1.0.15
/usr/local/src/egcs-971114
/usr/local/src/build
============================================================================
'newlib' and 'libgloss' are moved to 'egcs-971114' from 'newlib-1.8.0'.


My script file at /usr/local/src is
=============================================================================
prefix=/usr/local
host=i386-*-linux

target=$1

gver=egcs-971114

cd build

../binutils-2.8.1.0.15/configure --host=$host --target=$target \
				 --prefix=$prefix -v
make all
make install
rm -rf *

# Make cross tool include dir

mkdir $prefix/$target/include
cp -r ../$gver/newlib/libc/include/*  $prefix/$target/include

../$gver/configure --host=$host --target=$target --prefix=$prefix \
		   --with-gnu-as --with-gnu-ld -v
make all
make install
rn -rf *

=============================================================================

1) Target is arm-coff -- Error.

   * Without 'newlib' and 'libgloss", no error is found.

2) Target is a29k-coff -- Error.
   * "g77 requires ability to access exact FP representation of target machine"
   error is encountered while compiling files in 'egcs-971105/gcc/f' dir.
   * Without 'egcs-971105/gcc/f' directory, error is found at compiling c++.

   * Without 'f77' and 'c++', no error is found.

3) Target is m88k-coff -- Error
   * "g77 requires ability to access exact FP representation of target machine"
   error is encountered while compiling files in 'egcs-971105/gcc/f' dir.
   * Without 'egcs-971105/gcc/f' directory, no error is found.

4) Target is mn10200-elf without 'f' -- Good, No error.

5) Target is i960-coff without 'libgloss' -- Good, No error.

6) m68k-coff
   sh-elf
   mips-elf
   mips64-elf
   mn10300-elf
   powerpc-elf
   sparc-aout
   sparclite-aout
   hppa1.1-proelf
   i386-coff            --  Good, No error.

=============================================================================

PS : EGCS lists almost embedded 32/64 bit RISC/CISC processor. But, Alpha
  has no embedded target. For completeness, why don't you include alpha-foo
  like as m68k-coff.
