At least it generates the RA column:

I'm not sure I understand. The RA column is the column in the table w

Then an approach could be to patch the GDB unwinder to make it follow the GCC

Well, GCC doesn't generate 2 flavor of CIEs (on SPARC) so considerations that
apply

The correct approach would be to have gcc generate correct DWARF data.
Indeed, I have patch gdb to work around the inaccurate CIE.

Hi all,
From gcc documents, I know that if the condition code or comparison
result can be placed in any general register, or if there are multiple
condition registers, use a pseudo register. I want to use general
register, but I don't know how to do it. Could someone know that? And

Great.

Of course EH unwinding needs strictly correct CFI, simply not

I fail to see why, at least on SPARC

I fail to see why, at least on SPARC, %o7 should be good enough.
You set a breakpoint at the return address assuming that you
will reach it when you finish the function. On Sparc, if you
set it at the address in %o7, you will be setting the breakpoint

OK
I had make 2.81 installed from the get-go and it did
not conform to the "smart" make, but the first time I
tried to fix by installing texinfo just before "make
install" - NFG.
I installed texinfo and rebuilt the world - it worked.
Thanks - and yes I will do my bit to support GNU as
