[PATCH 5.15 225/356] gcov: add support for GCC 14

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Peter Oberparleiter <oberpar@xxxxxxxxxxxxx>

commit c1558bc57b8e5b4da5d821537cd30e2e660861d8 upstream.

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.
