Hi Guenter,
get_cycles is implemented as static inline which executes mfspr(SPR_TTCR).
SPR_TTCR is a constant. Normally that information seems to be passed on,
but not when get_cycles() is compiled through jitterentropy.
Any idea what might cause this ?
Then it may be the optimization issue as well that Peter indicated. May I ask
you for testing purposes (I do not have an OpenRISC) to remove the following
line from crypto/Makefile:
CFLAGS_jitterentropy.o = -O0
Yes, that fixes the problem (after I also removed the associated #error from
jitterentropy.c).
