1781001 - Downgrade some C++20 warnings-as-errors to warnings

Status: RESOLVED FIXED

(Firefox Build System :: General, task, P3)

Description

[Chris Peterson [:cpeterson]]

Downgrade some C++20 warnings-as-errors to warnings that we can fix after we compile as C++20 (bug 1768116). They don't need to block upgrading to C++20.

-Wambiguous-reversed-operator
-Wdeprecated
-Wdeprecated-anon-enum-enum-conversion
-Wdeprecated-enum-enum-conversion
-Wdeprecated-enum-float-conversion
-Wdeprecated-pragma

Downgrade some C++20 warnings-as-errors to warnings that we can fix after we compile as C++20 (bug 1768116). They don't need to block upgrading to C++20.

Suppress the -Wambiguous-reversed-operator warnings entirely for now because they are too noisy (with about 600 warnings).
