[Qemu-devel] [5109] Fix Sparc64 boot on i386 host: |

Date: |

Revision: 5109
http://svn.sv.gnu.org/viewvc/?view=rev&root=qemu&revision=5109
Author: blueswir1
Date: 2008-08-29 20:50:21 +0000 (Fri, 29 Aug 2008)
Log Message:
-----------
Fix Sparc64 boot on i386 host:
- move do_interrupt() back to op_helper.c
- move non-helper prototypes from helper.h to exec.h
- move some prototypes from cpu.h to exec.h
- do not export either set_cwp() or cpu_set_cwp() from op_helper.c,
but instead provide inline functions
