Fwd: Re: late generation of assemble code
by Paul Dufresne
had forgotten to reply also to the list... doing it now:
[cut the part where it was suggested to make package that contains LLVM
Intermediate Representation bitcode rather than CPU specific assembler]

John,
Where do you see overhead in the distribution of LLVM IR?
Advantages:
* more space on the hard disks of the servers, because they contains
repositories only for LLVM IR packages rather than one by supported
architectures
* less use of the CPU time of the servers because they don't optimize
code for specific CPUs
* very reduced cost for supporting more architectures, as code is
client-side generated
* faster code on clients with recent CPUs, because code is optimized for
them, and was not in the old way of doing because you had to distribute
for a common base CPU
* CPU specific code generation and optimizations can be done on idle
time of the clients... there is not much idle time of the servers

New CoreOS Assembler release v0.8.1
by Dusty Mabe
https://github.com/coreos/coreos-assembler/releases/tag/v0.8.1
Some highlights for this release:
- Many UX improvements to `cosa run`
- A lot of work around enhancing our support for GCP image uploads and manipulations.
- Add support for offline installs
- More multi-arch fixes and improvements
- Support installed tests in `/usr/lib/coreos-assembler/kola`
- There are now two new commands for making it easier to iterate faster
- `cosa build-fast` and `cosa buildinitramfs-fast`. See their help output for more information.
And of course many more fixes and features! Thanks to all the contributors!
