Hello,
my ARM-Linux board seems to be resistant against bus errors/misaligned data
access or the compiler does some magic to prevent these ;-)
Yes, the kernel fixes the unaligned access.
It would help me, to debug a program, when my board would abort with an error
message, so that I can isolate the bug.
Does someone know, if there exists something like a Linux option do
disable/enable data aborts?
Yes, if you want signals, do:
echo 4 /proc/cpu/alignment
... and your program should abort at any unaligned access.
