Thanks everyone! A blog post would be awesome, indeed.
Ben, I didn't have anything particular in mind, just curious about possibly
more ergonomic alternatives to profiling builds for getting this sort of
information. (Motivation similar to Richard's, I think.)

Interesting -- this is helpful to know. I had heard about DWARF support for
some years and thought tha

For windows we have Portable Executable (PE) as the container format.
This implies that the DWARF work is (unsurprisingly) completely inapplicable
for Windows.
It's not quite as simple. Dwarf info can be embedded into windows
Thanks for this!

Thanks Carter!
Yes I completely forgot about the unwinding librarys.
Sorry. My bad!
Best,

My understanding is that the platform specific part of ghc dwarf support
atm is the stack walking to generate dwarf data in stack traces. This is
because the dwarf stack walking Libs that are relatively mature are mostly
centered around elf?
It should still be possible with some work to use perf

Is that translation accurate? If so, perhaps we should use both names: if I see
that GHC x.y.z has DWARF support, I quickly scroll to the next bullet. If I see
that GHC x.y.z has support for platform-native debugging metadata and is now
compatible with e.g
Hi,
How's the integration of DWARF support coming along? It's probably one of
the most important improvements to the runtime in quite some time since

Is this stack trace support different than what we have currently?
