Bug ID: 114496
Summary: Documentation: "Non-Bugs" page should update/mention
something about -Wsign-conversion
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: web
Assignee: unassigned at gcc dot gnu.org
Reporter: Explorer09 at gmail dot com
Target Milestone: ---
Section 14.8 of GCC manual
"Certain Changes We Don’t Want to Make"
(https://gcc.gnu.org/onlinedocs/gcc-13.2.0/gcc/Non-bugs.html)
This item:
> Warning about assigning a signed value to an unsigned variable.
> Such assignments must be very common; warning about them would cause more annoyance than good.
Perhaps GCC should clarify this a bit. GCC now has the "-Wsign-conversion"
option that warns about similar signed-to-unsigned conversions. So what feature
in particular did GCC choose not to implement? The difference between this
"non-bug" item and the existing "-Wsign-conversion" is what I wish to see.

--- Comment #3 from Eric Gallager <egallager at gcc dot gnu.org> ---
Maybe the update could be just to clarify the "EnabledBy" rules for the
warning? i.e., something like "-Wsign-conversion is only and will only ever be
enabled by -Wconversion in C, and we will never have it enabled by -Wall or
-Wextra (unlike -Wsign-compare, which is enabled by -Wall in C++, and -Wextra
in C)."
(and maybe also include something about the new -Warith-conversion flag too?)
