From 4e8fbc1c975c667c61a3073da81b338b9bf61c37 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Mon, 11 Dec 2017 14:47:49 -0300 Subject: perf env: Adopt perf_env__arch() from the annotate code And use it in the libunwind case, with both passing a valid perf_env to extract the arch to be normalized from and passing NULL with the same semantic as in the annotate code: to get it from uname() uts.machine. Now the code to generate per arch errno translation tables (int/string) can use it to decode perf.data files recorded in a different arch than that where 'perf trace' (or any other analysis tool) runs.
