[Qemu-devel] [PATCH] esp: On qemu-system-sparc's esp, TC is not set properly

[Ryo ONODERA]

I does not understand hw/esp.c fully.
This patch supresses esp/TC related errors on NetBSD/sparc 5.1.2 or 6.0_RC2.

Please review the patch.

This is patch for https://bugs.launchpad.net/qemu/+bug/1055090 .
