Hello,
While running my script[1] parsing gcc/c-family/c.opt to extract
information about the new warnings for C++ programs, I've noticed that a
couple of new warnings in gcc 11 don't use the "Warning" flag which, I had
assumed, would be used for all warnings (with a couple of historical
exceptions). Was this assumption wrong, or could this have been an
oversight, i.e. should this flag be added to these warning too?
For the reference, the commits adding the warning were:
- 1d87302a8e2 (c++: Add -Wexceptions warning option [PR97675], 2020-11-03)
- 10ee6da64c5 (C++ Module options, 2020-12-01)
Thanks in advance,
VZ
You are right, thanks for heads up. I'm going to install the following obvious
patch
(and will add it to gcc-11 branch as well).
