[Qemu-devel] [PATCH 2/4] bsd-user: move arch/OS dependent code out of main.c |
|
Date: |
Thu, 19 Jun 2014 17:19:46 -0700 |
From: Stacey Son <address@hidden>
This change moves the cpu initialization and main loop code from
main.c to the OS and arch dependent directories. This eliminates
many of the #ifdef's in main.c. The cpu initialization and loop
code is now located in the arch directory along with target arch
support code.
