The conditional expression of ternary operator does not support action_params

Question

The conditional expression of ternary operator does not support action_params

Closed this issue 8 years ago · 2 comments

Hi, p4c compiler would yield ERROR: Undeclared identifier xxx, provided the ternary operator uses an action_param (e.g., xxx) in its conditional expression. This seems to be a bug (although easy to avoid by assigning the runtime value to a metadata field and using it for cond expressions instead).

Hi Shouxi,

It would be useful if you could provide a small P4 program to help us reproduce this issue.

Thanks
