It would help a lot if it included testcases for what various options / option combinations do / do not enable. I expect that each option continues to enable the warnings it does at present (so if a user explicitly does -Wreturn-type it also enables the -Wmissing-return warnings, for example) - but some warnings would start to be enabled by default. If someone does e.g. -Wno-implicit that would disable the default -Wimplicit-int; if they do -Wno-implicit -Wimplicit that would have the same effect as just -Wimplicit (so keeping the default warnings enabled, and possibly enabling others).

We should test the following: * default => run just -Wreturn-type * -Wreturn-type => Run both * -Wreturn-type + -Wmissing-return => Run both * -Wno-return-type + -Wmissing-return => Run just the second one * -Wno-return-type + -Wno-missing-return => Run none Do you see any other? > I expect that each option > continues to enable the warnings it does at present (so if a user > explicitly does -Wreturn-type it also enables the -Wmissing-return > warnings, for example) - but some warnings would start to be enabled by > default.

I will try to implement that later (I don't think -Wimplicit-int is necessary to enable -Wreturn-type by default). Besides that, are you OK with my changes? (with the tests updated) Thanks, Sylvestre

The test Wmissing-return2.c only has one of the two warnings. But as per "-Wreturn-type => Run both", and for backwards compatibility with the existing definition of -Wreturn-type, both warnings should appear for this test. (It's simply that only a subset of -Wreturn-type seems suitable to enable by default for C. Maybe the default subset, -Wreturn-type -Wno-missing-return (which is a combination that should also be included in the testcases), should have its own option name, although I don't know what that would be.)

I have touched more than 1200 test files and I would like to see that merged soon to avoid more conflicts. By the way, do you prefer a single commit for all tests or one per directory (gfortran, C++, gcc, OpenMP) ? Thanks Sylvestre

Each commit needs to avoid causing regressions. Thus, if a change to compiler behavior would cause an existing test to fail, the change to the test needs to be in the same commit as the change of behavior - or in a previous commit if the changed test works both with and without the compiler change.
