We used embedded stabs for SOM (the native format for 32bit PA). SOM is a
variant of COFF and could easily support dwarf I would think since
it had support for fairly arbitrary sections. Hell, it was already supporting
embedded stabs as well as HP's proprietary debugging format.
But I'd consider 32bit SOM on hpux11 dead too :-)
I don't disagree but 32bit SOM still builds on hpux11:

Suspect the change will cause a lot of warnings.
It might, but with stabs going away something needs to be done with these
legacy systems. Either they need to move into the modern world,
deal with the diagnostic or get dropped.
I believe the 32-bit SOM target should be deprecated. I'm the only one
maintaining it and I had some health issues earlier this year.
The current versions should suffice for several years.
Seems quite reasonable.
My main interest is the Debian parisc-linux target. It's fully up to date and
thousands of packages are available. Most kernels are 64-bit.
Since there's no 64-bit runtime for Linux, we still need the 64-bit hpux target
for 64-bit compile testing.
Agreed. Given that the 32bit linux and 64bit hpux targets both use ELF
+ dwarf, they're not in danger of significant fallout from the stabs
removal effort.
DWARF isn't supported because we lack named sections. That could be worked
around
but probably the gdb versions that work on 32-bit hpux11 wouldn't support DWARF.
I'd be a bit surprised if that were true. dwarf support has been around a long
long time in GDB. Hell, it was around when I did the original
64bit PA work back in the 90s.
There's a chance it might work with the right section names. However dwarf 5
wouldn't be supported. That's an issue that I noticed recently.
Yea, without a modern gdb, 32bit SOM would be stuck back in the dwarf2
era. But even that's better than embedded stabs.
