Doesn't the subject clearly mention "powerpc-unknown-linux-gnu"?

I am trying -O3 now.

I understand. But it's not always possible to change the code size, especia=
lly
when the code is not mine but some random upstream code.

What I don't understand is that other 32-bit architectures don't seem to be
affected. For example, hppa-unknown-linux-gnu is not affected.

And, secondly, using LLVM as the bootstrap compiler resolves the issue with
LLVM for me.=
