@ -3219,12 +3219,13 @@ Support for FreeBSD 1 was discontinued in GCC 3.2. Support for
FreeBSD 2 (and any mutant a.out variants of FreeBSD 3) was
discontinued in GCC 4.0.
In GCC 4.5, we enabled the use of @code{dl_iterate_phdr} inside boehm-gc on
FreeBSD 7 or later. In order to better match the configuration of the
FreeBSD system compiler: We also enabled the check to see if libc
provides SSP support (which it does on FreeBSD 7), the use of
@code{dl_iterate_phdr} inside @file{libgcc_s.so.1} (on FreeBSD 7 or later)
and the use of @code{__cxa_atexit} by default (on FreeBSD 6 or later).
In order to better utilize FreeBSD base system functionality and match

GCC 4.4 past 2010-06-20 leverage SSP support in libc (which is present
on FreeBSD 7 or later) and the use of @code{__cxa_atexit} by default
(on FreeBSD 6 or later). The use of @code{dl_iterate_phdr} inside
@file{libgcc_s.so.1} and boehm-gc (on FreeBSD 7 or later) is enabled
by GCC 4.5 and above.
We support FreeBSD using the ELF file format with DWARF 2 debugging
for all CPU architectures. You may use @option{-gstabs} instead of
