------------------------------------------------------ From: Peter Oberparleiter oberpar@linux.ibm.com Subject: gcov: add support for GCC 15 Date: Tue, 28 Oct 2025 12:51:25 +0100
Using gcov on kernels compiled with GCC 15 results in truncated 16-byte long .gcda files with no usable data. To fix this, update GCOV_COUNTERS to match the value defined by GCC 15.
Tested with GCC 14.3.0 and GCC 15.2.0.
