Subject: [openrisc] or1ksim basic.S error
hi all,here is the or1ksim log at the end of program, basic.S
i saw basic.S call 'report' function
but when it call report, it execute l.sw 0x0(r1),r2.
it reports
Exception 0x600 (Alignment) at 0x4000914, EA: 0xfffffffd, ppc:
0x4000914, npc: 0x4000918, #568
what's the matter of that ?
i simulate other c program, such as uart, it has no error.
and in support.c
i find report function is (in no OR1K define section)
void report(unsigned long value)
{
printf("report(0x%x);\n", (unsigned) value);
}
Thank you.
