What to do with hardware exception (unaligned access) ? ARM920T processor

[Vladimir Sterjantov]

Hi!

Processor ARM920T, chip Atmel at91rm9200.
Simple C code:

char c[30];
unsigned short *pN = &c[1];

*pN = 0x1234;

causes hardware exeption - memory aborts (used to implement memory 
protection or virtual memory).

We have a lot of source code, with pieces of code like this, which must 
be ported from x86 to ARM9.

Are there any compiler options to handle this exception?

I compile it by using arm-elf-gcc 4.3.2 under Linux.
binutils-2.18.

Thanks.
