When an AArch64 image contains C++ exceptions, merges all
.eh_frame sections into one
.eh_frame section and then creates the
.eh_frame_hdr section. This option is the default.
.eh_frame_hdr section contains a binary search table of
pointers to the
.eh_frame records. During the merge
armlink removes any orphaned records.
.eh_frame sections defined by the Linux Standard Base specification are supported. The
.eh_frame_hdr section is created according to
the Linux Standard Base specification. If armlink finds an unexpected
.eh_frame section, it stops merging, does not create the
.eh_frame_hdr section, and generates corresponding
Valid only for AArch64 images.
