++// The eh_frame section was usually writable (flags "aw") in older OS versions,
++// but can be made read-only (flags "a") under specific conditions, depending
++// on the assembler's behaviour (look for EH_TABLES_CAN_BE_READ_ONLY in
++// gcc-11.1.0/gcc/defaults.h).
++// To determine whether the eh_frame section is writable or read-only by
++// default, compile a simple program:
++//   gcc -S -fno-dwarf2-cfi-asm hello.c  (GCC >= 4.4)
++// or
++//   gcc -S hello.c                      (GCC < 4.4)
++// The result is that all modern systems (at least Ubuntu >= 16.04,
++// Red Hat Enterprise Linux >= 5, Fedora >= 13, Alpine Linux >= 3.7,
++// FreeBSD >= 11, DragonFly BSD >= 6, NetBSD >= 7, OpenBSD >= 6)
