Christian, thanks for your reply. Unfortunately, adding LEON3 support to the tool_chain script is not that easy.
binutils 2.22 doesn't fully support LEON3 (missing CAS instruction). I therefore did a quick attempt of bumping the version numbers in the script to binutils 2.24 and gcc 4.8.2, which however fails with undefined type uint64_t errors in libstdc++v3. I think there are basically three options for me: 1. Figure out how to compile the tool chain with the newer versions of binutils and gcc, which may, however, have uncertain effects on Genode (?). 2. Backport the missing LEON3 features to the versions currently used for the Genode tool chain. 3. Somehow work around the libc issues with the gaisler tool chain (if possible at all). Do you have any comments on this? I guess I'd go for the second option unless you have any other suggestions.
