Better split-objs support

[MichielDerhaeg]

I've been using the split-objs option everywhere for what I believe is over a year now. During this period it has caused zero problems and it produces significantly smaller binaries.

However, it's annoying that packages built with split-objs are not seperated from packages built normally. So it needs to be enabled all the time if you want the full benefit.

I wondered for how long this feature will remain experimental because it seems to work really well and it would nice for it to be fully supported.

I believe that split-objs has some compiler and linker overhead. Possibly not, though, as it doesn't need to load as much overall object code into memory.

Worth trying it out! One approach might be to add it as a configuration option that can also go in your global config.yaml, so you can enable split-objs globally if you want it.

It has some overhead, it can make the compilation process much slower. But you misunderstand, the option is already there, it is just marked as experimental and the built binaries are not seperated from the normally built ones. Which means i always have to turn it on. Sometimes, I don't need smaller binaries and i would like to turn it off without 'dirtying' my snapshot with bigger binaries.

Ah, yes, indeed it already is part of configuration. Well you can just put the following in your ~/.stack/config.yaml and you won't need to remember to do it anymore.

build:
  split-objs: true

I can buy that having separate binary results for this would be nice. I think that will fall under the umbrella of #3330

Dunno why I closed this
