Hi.

I've thinking about the file split about quite some time, mainly
in context of PR84402. I would like to discuss if it's fine for
maintainers of the target to make such split and into which logical
components can the file be split?

I'm suggesting something like:
- option-related and attribute-related stuff (i386-options.c - as seen in patch)
- built-in related functions
- expansion/gen functions - still quite of lot of functions, would make
  sense to split into:
  - scalar
  - vector
- prologue/epilogue, GOT, PLT, symbol emission
- misc extensions like STV, TLS, CET, retpolines, multiversioning, ..
- helpers - commonly used functions, print_reg, ix86_print_operand, ..

I am volunteering to make the split, hopefully early in the next stage1.

Thoughts?

Thanks,
Martin
