final observation on failure to build SH toolchain

[Robert P. J. Day]

  ok, here's my last post on the subject since i'm pretty sure i've
exhausted my knowledge on the subject.  the bug report is here:

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24445

but that talks about trying to build for SH4.  turns out, i didn't
even need to push it that far -- i can get a build error building for
SH3 just from what comes with crosstool-0.38 and a gcc-4.1 snapshot.

  here's a combination that *works* for SH3 (that is, it at least
completes building a toolchain and the test succeeds):

BINUTILS_DIR=binutils-2.16.1
GCC_DIR=gcc-4.0.1
GLIBC_DIR=glibc-2.3.5
LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0
GLIBCTHREADS_FILENAME=glibc-linuxthreads-2.3.5

TARGET=sh3-unknown-linux-gnu
TARGET_CFLAGS="-O -m3 -ml"
GLIBC_CONFIGPARMS="no-z-defs=yes"
GLIBC_EXTRA_CONFIG="--without-fp"
USE_SYSROOT=1

  now, all i have to do is make the following change and use an early
gcc-4.1 snapshot"

GCC_DIR=gcc-4.1-20050702

which generates the error:

  not even the same error, but it does show that even an early gcc-4.1
snapshot is not building for SH3.  sigh.

rday

p.s.  i can get a build using gcc-4.0.2 as well as gcc-4.0.1, so it's
clearly something that was introduced on the way to gcc-4.1.
