As I always wonder if my compiler could help me find more bugs,
and the list of warnings I enable tend to be very long,
and -Wall is not enough for me...
(This bug certainly depends on #44209: "Some warnings are not linked to
diagnostics options")
It would be great to have the following options:
(I really don't care for their names if you have better suggestions;
I focus on the functionality)
-Wevery: would enable all warnings known to gcc
================================================
This would allow reducing this (infamous) list:
-W -Wall -Wextra -Wstrict-aliasing=2 -Wfloat-equal -Wundef -Wconversion
-Winline -Wmissing-field-initializers -Wshadow -Wcast-align -Wformat=2
-Wsequence-point -Woverloaded-virtual
(I never know which one is enabled by -W, -Wall, -Wextra...)
to a single -Wevery with a few -Wno-XXXXXX
-show-warnings: would show the enabled warnings
================================================
An example usage would be:
$ gcc -c somefile.c -Wall -Werror -Wno-error=reorder -Wno-unused-function
..... -show-warnings
status name from
------------------------------------------------
ERROR address -Wall -Werror
warn reorder -Wall -Werror -Wno-error=reorder
- unused-function -Wno-unused-function
- clobbered (would be enabled by -Wextra)
...
------------------------------------------------
372 known warnings, 300 shown, 297 as errors (muted: 72)
If the team is interested, I'll consider providing a patch.
