Bug ID: 102049
Summary: Extend attribute deprecated to allow optional 2nd
argument
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
Clang implements something we don't have:
__attribute__((deprecated("message", "replacement")));
which we reject. We probably could allow it for the [[gnu::deprecated]]
form too (but not [[deprecated]]).
I wonder if we want some tweak that if the replacement argument is an
empty string, we don't warn -- this should allow code bases to gradually move
away from deprecated functions only when there's an actual replacement.
[[gnu::deprecated("insecure", "")]] void f(); // no replacement yet, don't warn
[[gnu::deprecated("slow", "add2")]] void add(); // warn, use add2
Does this seem worthwhile?
