Subject: [PATCH v1] perf: cast (struct timeval).tv_sec when printing
Date: Wed, 24 Feb 2021 18:24:10 +0000 [thread overview]
Message-ID: <20210224182410.5366-1-Pierre.Gondois@arm.com> (raw)
From: Pierre Gondois <Pierre.Gondois@arm.com>
The musl-libc [1] defines (struct timeval).tv_sec as a
'long long' for arm and other architectures. The default
build having a '-Wformat' flag, not casting the field
when printing prevents from building perf.
This patch casts the (struct timeval).tv_sec fields to the
expected format.
