Add m68k support to our unwinder.
_Unwind_GetLanguageSpecificData is supposed to return a _Unwind_Ptr.
This makes a difference on M68K as it uses a different register for
integer vs pointer values.
Cast context->ldsa to the correct return type.
Don't compile with fortification. It breaks makeinfo(1) for certain
input files (e.g. "cl.texi" shipped with Emacs 23.4) if it is compiled
with GCC 4.8.3 and "USE_SSP" set to "yes".
Document makeinfo(1) hack.
Save & restore FP registers.
Cast ptr to the correct return type (_Unwind_Ptr)
Add MKCTF

This variable separates CTF stuffs from MKDTRACE; we can build DTrace
solely without building and using them. This allows us to use DTrace
even if CTF stuffs have problems (actually they have now).

This variable would be merged into MKDTRACE eventually, once CTF stuffs
work correctly again.
Cast to _Unwind_Ptr here as well.
Bump date for previous.
Typo
snprintf -> vsnprintf in cpu_setmodel()
now this can actually work
hi christos
add missing include
Use C version of umul_ppmm for Clang on MIPS.
kill sprintf
fix unused/uninitialized
fix unused
Bias the cfi pc expr by nbytes since vax pcrel are relative to end of the
relocation, not the beginning.  By adding the size of relocation, it will
become relative to the start of the relocation.
kill sprintf
fix sprintf.
