Here is the result of running Debian's busybox-static for sparc64: $ sparc64-linux-user/qemu-sparc64 /usr/gnemul/qemu-sparc64/bin/busybox ls -l block.c ?rwxr-x--T 1 stefan root 1378329541 Jan 1 1970 block.c
It's obviously wrong. All other user emulations return the correct result: $ busybox ls -l block.c -rw-r--r-- 1 stefan stefan 131462 Sep 3 21:13 block.c In a first analysis of this, I noticed that it is impossible to run qemu-sparc64 under gdb (raised fatal signal). I was also surprised to see that target_stat64 is unused. Regards, Stefan
