[FPEnv][Clang][Driver] Use MarshallingInfoFlag for -fexperimental-strict-floating-point

Authored by kpn on Oct 7 2020, 10:37 AM.



As of D80952 we are disabling strict floating point on all hosts except those that are explicitly listed as supported. Use of strict floating point on other hosts requires use of the -fexperimental-strict-floating-point flag. This is to avoid bugs like "" (which has an incorrect link in the previous review).

In the review for D80952 I was asked to mark the -fexperimental option as a MarshallingInfoFlag. This patch does exactly that.

The previous tests continue to work correctly so I haven't included a new one here. I can if needed, but I would need guidance since I don't know what would need to be tested.

Hi Kevin, sorry for the late response.

I don't think adding new tests is necessary as long as the flag is used in existing ones.


In D82756, we've replaced the "default value" argument with a list of options that can imply the current flag. If empty or omitted, we set the default value to false automatically. Could you please remove the "false" argument?

No worries!

The option does already have tests that verify correct operation.


Will do.
