------------------------------------------------------ From: Peter Oberparleiter oberpar@linux.ibm.com Subject: gcov: add support for GCC 14 Date: Mon, 10 Jun 2024 11:27:43 +0200

Using gcov on kernels compiled with GCC 14 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 14.

Tested with GCC versions 14.1.0 and 13.2.0.
