4d12bfcd15 Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.

47c1ea4ca3 Remove movw/movt due to linker problems.
Check for 0 divisor and __aeabi_idiv0 if needed (EABI && _LIBC only).

1239c2bb08 Publish explicit_memset and consttime_memequal in userland libc.
Remove the double-underscore from the userland versions, and do the
weak alias dance instead, now that these are public parts of libc.

As discussed on tech-userlevel:

https://mail-index.netbsd.org/tech-userlevel/2013/06/24/msg007843.html
(option 3)

495fdb7e9a Make explicit_memset match memset's return value. 2013-08-28 15:46:23 +00:00

cc79193075 Fix sense of consttime_memequal and update all callers.
Now it returns true (nonzero) to mean equal and false (zero) to mean
inequal, as the name suggests.

As promised on tech-userlevel back in June:
