On line 6142, column 31, gcc throws an error complaining about the '!=' comparison in the expression
'&& !op.bitfield.reg64 != 1`
I changed it to '&& ((!op.bitfield.reg64) != 1)' which then make can continue compiling without errors.

hi,
When I try to use timer related function in or1k-support.h, there are few lines demo which I paste below:
void tick_handler(void) {
// Make schedule decision
// and set new thread
or1k_timer_reset();
// End of exception, new thread will run
}
int main() {
// Configure operating system and start threads..
// Configure timer
or1k_timer_init(50);
or1k_timer_set_handler(&tick_handler);
or1k_timer_set_mode(SPR_TTMR_SR);
or1k_timer_enable();
// Schedule first thread and die..
}

But I can not find define of SPR_TTMR_SR used by or1k_timer_set_mode function.
or1k_timer_set_mode(SPR_TTMR_SR);

I tried to get SPR_TTMR_SR define from a file called spr-defs.h in mor1k-env-dev github
#define SPR_TTMR_SR 0x80000000 /Signle Run/
#define SPR_TTMR_CR 0xC0000000 /Continuous Run/
But it does not work at all.

So where I can get the right define of SPR_TTMR_SR used by or1k-support.h?

Thanks.

I found this error two months ago but I couldn't open an issue at that time so I wrote it on opencores.org under the nickname meitoku.

"Some programs that use timer works well with toochain versions before April 2014 now behave erratically.
Example: timer.c in https://github.com/juliusbaxter/orconf2013/blob/master/sw/timer/timer.c. It is a led counter, but now with the latest or1k-gcc commit (at that time is 62a1a271e5fecc9fecdfc0961f76fdfddf43d6a7), the timer didn't work, first one led turned on, then all the led flashed immediately. When I switched to commit d2093f8f4d182be22b24b459badd9f555859cc6f of or1k-gcc and commit 7d53ef07ae838a707e2ca8a467e51cd1174cf388 of or1k-src, I got no such problem."

@wallento told me that this error was caused by a modification in or1k-src.
