Hum. Are you sure it's anything related to the ppc backend at all? This test doesn't work with an x86_64 host either. qemu: fatal: Trying to execute code outside RAM or ROM at 0x004001ba EAX=80000011 EBX=00009500 ECX=c0000080 EDX=00000000 ESI=00000000 EDI=00542000 EBP=00000000 ESP=0044abbc EIP=004001ba EFL=00000046 [---Z-P-] CPL=0 II=0 A20=1 SMM=0 HLT=0 ES =0010 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] CS =0008 00000000 ffffffff 00cf9a00 DPL=0 CS32 [-R-] SS =0010 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] DS =0010 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] FS =0010 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] GS =0010 00000000 ffffffff 00cf9300 DPL=0 DS [-WA] LDT=0000 00000000 0000ffff 00008200 DPL=0 LDT TR =0000 00000000 0000ffff 00008b00 DPL=0 TSS32-busy GDT= 0040800a 00000447 IDT= 00000000 000003ff CR0=80000011 CR2=00000000 CR3=00407000 CR4=00000020 DR0=00000000 DR1=00000000 DR2=00000000 DR3=00000000 DR6=ffff0ff0 DR7=00000400 CCS=00000000 CCD=00000000 CCO=SARL EFER=0000000000000000 FCW=037f FSW=0000 [ST=0] FTW=00 MXCSR=00001f80 FPR0=0000000000000000 0000 FPR1=0000000000000000 0000 FPR2=0000000000000000 0000 FPR3=0000000000000000 0000 FPR4=0000000000000000 0000 FPR5=0000000000000000 0000 FPR6=0000000000000000 0000 FPR7=0000000000000000 0000 XMM00=00000000000000000000000000000000 XMM01=00000000000000000000000000000000 XMM02=00000000000000000000000000000000 XMM03=00000000000000000000000000000000 XMM04=00000000000000000000000000000000 XMM05=00000000000000000000000000000000 XMM06=00000000000000000000000000000000 XMM07=00000000000000000000000000000000 Aborted (core dumped) This happens after one of the writes to %cr0. Of course, the test works with kvm enabled, so I don't blame the test so much as the target-i386 front end... This is not new breakage, either. I've checked back through 1.4.0 and I can't make it work with any version of TCG. r~
