--- Comment #6 from Ian Lance Taylor <ian at airs dot com> --- All the insns in sh_expand_epilogue need to be examined to see if they need REG_CFA notes. Some of them already have them. I don't know what more are needed. For example, look at the changes made to the i386 backend when rth added the general support for unwinding through epilogues: http://gcc.gnu.org/ml/gcc-patches/2009-05/msg00277.html
