FPU Exception error driving me crazy!

[gambiting]

I'm having most irritating error EVER!
I have a structure like this one:

Code: Select all

struct ammo_struct
{
	float x;
	float y;
	float xmov;
	float ymov;
	bool draw;
};

But when I try to do ANYTHING with it,like

Code: Select all

ammo[i].x=1;

It gives me FPU Exception error in PSPLink:

Code: Select all

host0:/> ./blowup.prx

I have many structures in my program,all of them are working fine,but this is giving me such problems. I've already tried psp-addr2line,but all I get is ??(yes,it's compiled with -g option).Please help

Edit: I've seen that it's possible to disable Fpu Exceptions - how can you do that?

For a start you need to subtract the module base address from the EPC to get a relative address for use in psp-addr2line, you could try doing 'calc $epc-$mod' in your psplink shell when it crashes, depends what version of psplink you have as to whether it will work.

As for disabling the fpu exceptions then include pspfpu.h and call pspfpu_set_enable(0);

Based on the instruction it is dying at it looks like the values you are comparing somewhere are completely foobar. You could always try it in GDB.

I can't get anything from PSPLINK,even with address calculated your way,but disabling FPU exceptions works for now....but I doubt if it's the best way of handling it.But thanks very much for you input :D

Setting it like this:

Code: Select all

ammo[i].x = 1.0f;

Is probably more "proper" in terms of coding. It might be throwing an exception because you gave it an int. I dunno, it could be psplink.

[pspZorba]

Are you sure that :
i >=0
and
i < the max bound

Is ammo static-ly defined or dynamically allocated ?
