Hello, We (AdaCore) appreciate having triplets like e500v2-wrs-vxworks or e500v2-wrs-linux work out of the box.
The attached patch is something we have been using for a while for this purpose and we thought others might find it useful as well. The general idea is to have e500 treated essentially as powerpc except selecting a default "spe" os extension when appropriate for proper ABI selection. On the gcc front, we leverage this further by selecting a default with_cpu, typically 8540 for e500v1 or 8548 for e500v2 (original patch submission at https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01300.html) The patch passes the existing tests + the few added cases. OK to commit ? Thanks in advance for your feedback, With Kind Regards, Olivier 2014-09-17 Olivier Hainque <hain...@adacore.com> * config.sub: Accept e500v[12] cpu names. Canonicalize to powerpc and add a "spe" suffix to the os name when required to select the proper ABI. * testsuite/config-sub.data: Add tests for e500v[12]-elf, e500v2-wrs-vxworks, e500v2-vxworksae and e500v2-wrs-linux.
