So I applied the patch and ran the testsuite on powerpc64-linux.
Turns out I was correct to suspect the warning would trigger when it
shouldn't. These new failures appeared:
Huh? I ran those tests and they pass!
Just to be sure, I've just rebuilt and re-run, twice, and they still pass.
I was testing natively, but I see a whole lot of errors on an
x86_64-linux to powerpc64-linux cross too, configured using
/src/binutils-gdb/configure --build=x86_64-linux \
--target=powerpc64-linux --disable-nls --enable-plugins \
--disable-gdb --disable-sim --disable-readline --disable-libdecnumber
/path/to/binutils/configure --build=i686-pc-linux-gnu \
--target=powerpc-linux-gnu --host=i686-pc-linux-gnu \
--enable-64-bit-bfd --disable-gdb \
--disable-libdecnumber --disable-readline \
--disable-sim --disable-nls --enable-plugins
Looks like the main difference is mine runs on 32-bit hosts. I hope
that's not significant!
/me goes to check.
