[test-suite] Support GCC compilation of Microbenchmark MemFunctions.

Authored by naromero77 on Dec 14 2020, 10:21 PM.



GCC and Clang diverged in how attribute is supported. GCC gives a compile-time error if there is an attribute in the function-definition and needs to be in the forward declaration. Clang does not like attribute in the forward declaration and requires it in the function-definition. This is the only benchmark in the test suite not compiling with GCC.

Thanks for the patch. Apparently both gcc and clang are fine if the attribute is placed before the definition:, so we could do without the ifdefs.
(Though gcc does not know about the attribute, but that's also the case with the current version)

OK, let's do that instead. Best to avoid ifdefs. Will update patch soon.

  • Place attribute before the definition and avoid ifdef.
