- Fix issue of virtio-9p-ccw having been mistakenly dropped from qemu (bsc#1182496) hw-s390x-fix-build-for-virtio-9p-ccw.patch - Tweaked some spec file details to be again compatible with quilt setup using the spec file as input - Remove BuildRequires that were added in anticipation of building ovmf within this package. We have not taken that route OBS-URL: https://build.opensuse.org/request/show/874876 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=619

Subject: usb: Help compiler out to avoid a warning on x86 compilation
|
|
|
|
Include-If: %ifarch %arm %ix86 ppc
|
|
|
|
There is an assert present which already should give the compiler
|
|
enough information about the value of i as used in the snprintf,
|
|
but if I remember right, for x86, because memory is tighter some of
|
|
the compiler smarts are turned off, so we get the uninformed warning
|
|
there and not on other archs. So on x86 only we'll add some code to
|
|
help the compiler out, so we can again compile qemu with
|
|
--enable-werror.
