[Qemu-devel] [PATCH 09/20 v3] target-i386: add x86cpu_vendor_words2str() |
Date: |

Make for() cycle reusable for the next patch
Signed-off-by: Igor Mammedov <address@hidden>

v3:
fix/swap vendor2 and vendor3 order
Spotted-By: Eduardo Habkost <address@hidden>
v2:
place x86cpu_vendor_words2str() a bit earlier, before feature
arrays to avoid compile error when vendor property is converted
static property.
