+cmake crashes on qemu-alpha-user with Illegal Instruction
+
+I tried building cmake on Debian unstable for Alpha today using qemu-user and the compiled cmake binary crashed with "Illegal Instruction":

+Illegal instruction

+Error when bootstrapping CMake:
+Problem while running initial CMake

+
+I'm working on creating a chroot for download to reproduce the issue.
+
+Can someone remind me how I can print the disassembly in this case?

+It seems halt instruction is not implemented for qemu-user, only for qemu-system:
+
+
+1286 #ifndef CONFIG_USER_ONLY

+1365 static DisasJumpType gen_mtpr(DisasContext *ctx, TCGv vb, int regno)
+1366 {
+1367     int data;

+1393         return DISAS_PC_STALE;
+...
+1437 }
+1438 #endif /* !USER_ONLY*/
+
+...
+2673     case 0x1D:
+2674         /* HW_MTPR (PALcode) */
+2675 #ifndef CONFIG_USER_ONLY
+2676         REQUIRE_TB_FLAG(ENV_FLAG_PAL_MODE);
+2677         vb = load_gpr(ctx, rb);
+2678         ret = gen_mtpr(ctx, vb, insn & 0xffff);
+2679         break;
+2680 #else
+2681         goto invalid_opc;
+2682 #endif
+
+
+Of course.  Trying to use halt from userland on hw will SIGILL as well.
+
+There is no call insn in your listing at 0x40007fd988,
+so the easy assumption is that the return address has
+been corrupted on the stack.
+
+You'll have to dig deeper than just the insn listing.
+
+It also produces that Illegal Instruction on Gentoo. However, the exact same cmake binary runs without issue on real hardware.
+
+Some additions: qemu-mips64, qemu-arm, qemu-aarch64 doesn't have this problem (I'am using it with the same version of cmake compiled to/under those, and real HW).
+
+The QEMU project is currently considering to move its bug tracking to
+another system. For this we need to know which bugs are still valid
+and which could be closed already. Thus we are setting older bugs to
+"Incomplete" now.
+
+If you still think this bug report here is valid, then please switch
+the state back to "New" within the next 60 days, otherwise this report
+will be marked as "Expired". Or please mark it as "Fix Released" if
+the problem has been solved with a newer version of QEMU already.
+
+Thank you and sorry for the inconvenience.
+
+
+[Expired for QEMU because there has been no activity for 60 days.]
+
+
+This is an automated cleanup. This bug report has been moved to QEMU's
+new bug tracker on gitlab.com and thus gets marked as 'expired' now.
+Please continue with the discussion here:
