Re: [PATCH] Fix DW_CFA_set_loc handling

What is 'this' exactly? 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.
