Why did Jakub need to write a patch? > GCC (4.1 and 4.2) was fixed so that it no longer generates (as many) DW_CFA_set_loc. My understanding is that DW_CFA_set_loc can still be generated if GCC's hot-cold section partitioning is used and perhaps in other cases as well. This does not change the fact that the .eh_frame optimizations were broken in ld. So I think Jakub's patch is still needed. I will try to test the ld patch on my MIPS system (with the GCC PR 29132 patch reverted), but that I will not be able to do that for several days. David Daney
