Bug ID: 97507
Summary: Move __gcov_exit from per-object .fini_array.00100 to
libgcov
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: gcov-profile
Assignee: unassigned at gcc dot gnu.org
Reporter: i at maskray dot me
CC: marxin at gcc dot gnu.org
Target Milestone: ---
Per object file .fini_array.00100 wastes space. __gcov_exit can be called in
libgcov. It can be registered via atexit (if first run) in __gcov_init.
The Linux kernel does not call destructors and currently discards .fini_array
and .fini_array.* `gcc -fprofile-arcs` is currently one reason that
.fini_array needs to be discarded (another reason is kasan. I don't know other
reasons)
