Subject: [PATCH 16/22] perf diff: Use llabs() with 64-bit values
Date: Thu, 28 Nov 2019 10:40:21 -0300	[thread overview]
Message-ID: <20191128134027.23726-17-acme@kernel.org> (raw)
In-Reply-To: <20191128134027.23726-1-acme@kernel.org>

From: Arnaldo Carvalho de Melo <acme@redhat.com>

To fix these build errors on a debian mipsel cross build environment:

  builtin-diff.c: In function 'block_cycles_diff_cmp':
  builtin-diff.c:550:6: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
    550 |  l = labs(left->diff.cycles);
        |      ^~~~
  builtin-diff.c:551:6: error: absolute value function 'labs' given an argument of type 's64' {aka 'long long int'} but has parameter of type 'long int' which may cause truncation of value [-Werror=absolute-value]
    551 |  r = labs(right->diff.cycles);
        |      ^~~~
