[Qemu-devel] Q: SPARC support?

[Qemu-devel] Q: SPARC support?

[Nardmann, Heiko]

Using the given SPARC patch I have been able to compile and run (i.e. start) 
qemu. But it core dumps after opening the X window inside the function 
cpu_exec(). Here is the problematic section:

                __asm__ __volatile__("call      %0\n\t"
                                     "mov       %%o7,%%i0"
                                     : /* no outputs */
                                     : "r" (gen_func)
                                     : "g0", "i0", "i1", "i2", "i3", "i4", 
"i5", "i7",
                                        "l0", "l1", "l2", "l3", "l4", "l5", 
"l6", "l7");

Maybe someone (SPARC asm guru) could explain what is happening here (or should 
happen) ... ?

My machine is a Fire V250 (UltraSPARC-IIIi).

Hi,

Would you care to tell which tools do you use and which versions?
(like gcc, etc..)

Thanks,
Hetz

Sure; here it comes ...

- - Solaris 9 on Sun Fire V250 (UltralSPARC-IIIi)
- - GNU make 3.80 (package SFWgmake)
- - gcc 3.2 (package SMCgcc)
- - Assembler: as: Sun WorkShop 6 update 2 Compiler Common 6.2 Solaris_9_CBE 
2001/04/02
- - Linker: ld: Software Generation Utilities - Solaris Link Editors: 5.9-1.377

Shall I give Sun Forte compiler a try? Or use a different gcc version?

maybe you should give gcc 3.4.x a try.

won't work / not necessary.

Please tell me more about the QEMU source tree you used. Was it latest 
cvs or do / did you use http://www.qemu.com/qemu-0.6.1.tar.gz  ?

Thanks for the hint!

I have recompiled qemu using gcc 3.4.2 and now it works fine. I currently 
cannot tell whether it is fast or not since I get the display via internet; I 
am going to check this next week when I sit in front of the machine locally 
resp. in the same local network.

It was official 0.6.1 - not CVS.
