5 | tools/libxc/xc_dom_arm: add missing variable initialization | ||
6 | |||
7 | The variable domctl.u.address_size.size may remain uninitialized if | ||
8 | guest_type is not one of xen-3.0-aarch64 or xen-3.0-armv7l. And the | ||
9 | code precisely checks if this variable is still 0 to decide if the | ||
10 | guest type is supported or not. | ||
11 | |||
12 | This fixes the following build failure with gcc 7.x: | ||
13 | |||
14 | xc_dom_arm.c:229:31: error: 'domctl.u.address_size.size' may be used uninitialized in this function [-Werror=maybe-uninitialized] | ||
15 | if ( domctl.u.address_size.size == 0 ) | ||
