Enable GCC stack protection (aka Propolice) for userland: - It is opt-out for now so as to give it maximum testing, but it may be turned opt-in for stable branches depending on the consensus. You can turn it off with WITHOUT_SSP. - WITHOUT_SSP was previously used to disable the build of GNU libssp. It is harmless to steal the knob as SSP symbols have been provided by libc for a long time, GNU libssp should not have been much used. - SSP is disabled in a few corners such as system bootstrap programs (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves. - It should be safe to use -fstack-protector-all to build world, however libc will be automatically downgraded to -fstack-protector because it breaks rtld otherwise. - This option is unavailable on ia64. Enable GCC stack protection (aka Propolice) for kernel: - It is opt-out for now so as to give it maximum testing. - Do not compile your kernel with -fstack-protector-all, it won't work.

Provide support in loader for booting 64-bit PowerPC kernels. Like amd64, 64-bit PowerPC kernels are loaded by a 32-bit loader, since nearly all powerpc64 firmwares execute in 32-bit mode. 2010-07-11 20:49:22 -04:00			`.if ${MACHINE_ARCH} == "powerpc64"`

Rename the linker emulation name for powerpc and powerc64. This is needed that we can also use the upstream binutils linker where we have to have a unique name for the FreeBSD emulation. 2011-11-19 14:25:57 -05:00			`LDFLAGS+= -m elf32ppc_fbsd`
