sh4-cross-compiling-gcc-3.0.2 build fails during assembly

[Steven Mueller]

Hello all,

Recently I've been having trouble compiling gcc 3.0.2 targeting the
Hitachi Super Solution engine sh4.  The script I've been using to
automate the build, developed by my colleague Dan Kegel and me, is
available online at

http://www.ugcs.caltech.edu/~diffusor/build-sh4-gcc3.sh

It uses the binutils in Montavista's HardHat 2.0 sh4 cross development
kit and installs itself into that hierarchy.

We'd been using this script successfully through a week or two ago,
but now it fails when it reaches the first cross-assembly step.
Perhaps it's using the wrong as for some reason?  If someone could
shed some light on debugging this weirdness, such as how and where the
cross-assembler location is determined and how we might be able to
find out which assembler it's using, that'd be great.  Copy-pasting
the offending line from the log and adding the -v and the -save-temps
options was not as enlightening as I would have liked.

The build machine is a PIII running the debian testing/Woody
distribution with gcc package version 2.95.4-6.  The build also fails
under 2.95.4-8.  

The messages leading up to the failure are as follows:

echo '#define FLOAT' > fp-bit.c
echo '#ifdef __LITTLE_ENDIAN__' >> fp-bit.c
echo '#define FLOAT_BIT_ORDER_MISMATCH' >>fp-bit.c
echo '#endif'           >> fp-bit.c

A quick search on Google indicates these types of errors are pretty
common for a mismatching assembler architecture...

Thanks,

In your script:

| (
| ln -s sh4el-hardhat-linux  sh4-linux
| cd bin
| ln -s sh_sh4_le-ar sh4-linux-ar
| ln -s sh_sh4_le-ld sh4-linux-ld
| ln -s sh_sh4_le-nm sh4-linux-nm
| ln -s sh_sh4_le-ranlib sh4-linux-ranlib
| ln -s sh_sh4_le-strip sh4-linux-strip
| )

you don't appear to set up sh4-linux-as. The new GCC, therefore, might
be using the host assembler.

You could try repeating the failing compile manually, adding '-v' to
check which assembler is being used.
