Thank you all for the nice words! And especially to Honza, who was my diploma
thesis supervisor and showed me the community.

Actually there's a funny story about the thesis: I was seeking for a topic for 
diploma thesis
somewhen in 2011 and so I wrote to Honza. And as we know Honza, he didn't reply 
in a couple
of weeks. However, as I was returning from a pub right before Christmas this 
year, I met him
near the university campus (Malostranske namesti) and I reminded him the email. 
He replied
and that's how it all began.

Life is full of wonderful moments of coincidence.

Re: Clarification on newlib version for building AMDGCN offloading backend

Hi,

I'm working on adding a build recipe for GCC with AMDGCN offloading backend in 
Spack. Can anyone clarify the following sentence listed on the wiki?


The Newlib version needs to be contemporaeous with GCC, at least until the ABI 
is finalized.



What are the correct contemporaneous versions for each version of GCC >= 10?


Just match the dates and you'll probably be fine. We've mostly 
synchronised the ABI changes across the GCC mainline and the development 
branch precisely because the Newlib dependency is shared.


Right now the required version of Newlib is 4.3.0.20230120. Prior to the 
ABI change a month or so ago you would have to use a Newlib snapshot.


I wouldn't recommend spending very much of your valuable time on 
enabling old versions of these toolchains.

Re: Clarification on newlib version for building AMDGCN offloading backend

[Wileam Yonatan Phan via Gcc]

Hi Andrew,

Thanks! I've created the first draft as a GitHub PR here:


I think it still needs some work on the part where it builds LLVM utilities 
with CMake.
As much as I want supporting only the newest GCC version, Spack currently 
supports building all stable versions of GCC from the tarballs, as well as 
latest develop branch, so I've enabled all versions >= 10.

Thanks,
Wil
