Add --std=19 command line option #1981
Conversation
Currently, all behaviour is the same as for --std=08, except for the standard library search path. No standard libraries exist yet, so running ghdl with --std=19 will fail.

I'm not sure how exactly this library compatibility concept works. Should -2019 be compatible with -2008? Is this something that can still easily be decided later?

Yes, we can decide later. But I think we need to have dedicated 2019 libraries, as at least std was extended.

LGTM.
Maybe we want to update the first sentence of the "Main features" section of the README: https://github.com/ghdl/ghdl#main-features.

No, that was just an accidental push to the wrong branch, which I reverted. Thanks for looking out for that though! |

This is ok for me, but I will first release v2.0 before merging. |
Description
This simply adds the command line option and updates the documentation. There is not yet any difference in simulator behaviour between
--std=08and--std=19. Furher, since no 2019 standard library has been added yet,--std=19can't actually be used outside of bootstrapping.
