I've recently tried a i686-unknown-linux-gnu --enable-targets=all
bootstrap, which failed to link the 64-bit jv-convert etc.:
./.libs/libgcj.so: undefined reference to `ffi_raw_call'
./.libs/libgcj.so: undefined reference to `ffi_prep_raw_closure_loc'
./.libs/libgcj.so: undefined reference to `ffi_prep_cif_machdep'
./.libs/libgcj.so: undefined reference to `ffi_prep_closure_loc'
./.libs/libgcj.so: undefined reference to `ffi_call'
collect2: error: ld returned 1 exit status
make[5]: *** [jv-convert] Error 1
This happens because libffi doesn't build the x86_64 objects in this
configuration. The following patch fixes this and allowed (together
with a libjava patch to be submitted shortly) the bootstrap to finish.
I've also bootstrapped x86_64-unknown-linux-gnu without regressions.
The same issue still exists in upstream libffi, and should be harmless
without --enable-targets=all since the added files are empty then.
Ok for mainline gcc?
