So probably 14.3 will have 10 counters in total.
Do you have links? I'd expect that to mean that GCC 15 will have 10 counters, not GCC 14.3. > >>> --- a/xen/common/coverage/gcc_4_7.c >>> +++ b/xen/common/coverage/gcc_4_7.c >>> @@ -28,8 +28,10 @@ >>> #define GCOV_COUNTERS 10 >>> #elif GCC_VERSION < 100000 >>> #define GCOV_COUNTERS 9 >>> -#else >>> +#elif GCC_VERSION < 140100 >> The situation is a little less clear here because the development window is >> fuzzy to cover.

In GCC's numbering scheme, .0 is the dev window and .1 is the release. The 9th counter will have appeared somewhere in the dev window, but that's all GCC 14 as far as we're concerned. ~Andrew
