catch3/src/catch2/internal/catch_unique_name.hpp, branch v3.15.1 Progmasoft Catch3: an independently maintained C++17 test framework with a parallel runner, property checks, snapshots and structured results. Suppress __COUNTER__ warning from newest Clang versions 2026-04-01T08:34:58+00:00 Martin Hořeňovský 2026-04-01T08:34:54+00:00 51b0532d1fba061d0802ccfd906cc87fc2dd49c2 Ideally we could suppress the warning locally in the `UNIQUE_NAME` macro, but that runs into at least 2 issues: 1) Clang actually does not consider the warning as coming from inside the `UNIQUE_NAME` macro, even though it correctly points to its expansion as the problem. This means that adding `_Pragma`s inside the macro around the __COUNTER__ usage does not actually silence the warning. 2) Adding the local suppressions anyway breaks the expansion of `MAKE_NAMESPACE` macro inside the templated test case macros. This can be fixed for the newest clang version by removing its use and using the uniqued `TestName` for the namespace name directly, but this breaks compilation on GCC, and older Clang versions. Because of these issues, we introduce global warning suppression for `-Wc2y-extensions` to be done with it. We should revisit this if Clang 23 fixes the local pragma based suppression, when it might be worth the effort to rework the templated test case macros to support it. Closes #3076 
Ideally we could suppress the warning locally in the `UNIQUE_NAME` macro,
but that runs into at least 2 issues:

1) Clang actually does not consider the warning as coming from inside the
   `UNIQUE_NAME` macro, even though it correctly points to its expansion
   as the problem. This means that adding `_Pragma`s inside the macro
   around the __COUNTER__ usage does not actually silence the warning.

2) Adding the local suppressions anyway breaks the expansion of
   `MAKE_NAMESPACE` macro inside the templated test case macros. This can
   be fixed for the newest clang version by removing its use and using
   the uniqued `TestName` for the namespace name directly, but this breaks
   compilation on GCC, and older Clang versions.

Because of these issues, we introduce global warning suppression for
`-Wc2y-extensions` to be done with it. We should revisit this if Clang 23
fixes the local pragma based suppression, when it might be worth the effort
to rework the templated test case macros to support it.

Closes #3076
