[ECOS] gcc for sh-elf

[ECOS] gcc for sh-elf

[Stephen Williams]

I'm setting myself up for Hitachi SH processors, and have tried to follow
the instructions for building the development tools for eCos. Binutils
seems to compile fine, but I'm stuck at the compiler.

The compiler proper seems to build, but it fails when trying to build
tcrtbegin, as shown below. I've tried a couple different snapshots with
identical results. Have I missed something?

[snip compiler build error]

Probably not. It's simply a bug by the looks of it :(. I think you'd better
look at http://gcc.gnu.org/ and see about asking on the gcc mailing list.

I've long since given up on this and eCos. Getting the extraneous tools
compiled on my alpha was pretty much hopeless, and I was running out of
time to debug broken instructions.

I have my own C/C++ runtime that does not depend on tcrtbegin or newlib,
and patching gcc configuration to support uCR and sh turned out to be
faster. Less of a learning curve for me, too. I've had uCR working on
my Linux/alpha for a while now, so doing the needed SH specific stuff
and updating to more recent compilers went pretty smoothly.

I've got my SH7750 / SolutionEngine working pretty well, now.

Thanks for responding, though. Wish I had time to do something about it.
