Subject: [Qemu-devel] [PATCH] decodetree: Force Python to print unsigned values
Date: Sun, 11 Nov 2018 01:02:59 +0100 [thread overview]
Message-ID: <20181111000259.7665-1-f4bug@amsat.org> (raw)
Python internal representation is signed, so unsigned values
bigger than 31-bit are interpreted as signed (and printed with
a '-' signed).
Mask out to force unsigned values.
