[microblaze-uclinux] Compiler hangs

["Patrick Robin" <circaeng@xxxxxxxxxxx>]

Hello,

mb-gcc hangs when compiling the simple code bellow with optimization turned 
on. Seems to be related to 64 bit variables. I open a webcase with Xilinx 
but since uClinux uses "unsigned long long" variables and -01 optimization, 
I was wondering if anyone else saw this problem. In a larger program, it 
seems to be possible to make the code compile by juggling things around but 
the resulting code is unstable and hangs. THis doesn't happen with 
optimization turned off.

#include "xbasic_types.h"

typedef struct {

Xuint32 N;

} FGen;

//==================================================================
void FGen_runSingle(FGen *fg) {

unsigned long long z64; //unsigned 64 bits
z64=((z64<<29))/48828125;
fg->N=(Xuint32)z64;
}
