From a00dc319e98161949aa87f71a17db32e925c3257 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Fri, 25 May 2012 23:13:44 +0200 Subject: perf record: Fix branch_stack type in perf_record_opts The attr.branch_sample_type field is defined as u64 by the API. As such, we need to ensure the variable holding the value of the branch stack filters is also u64 otherwise we may lose bits in the future. Note also that the bogus definition of the field in perf_record_opts caused problems on big-endian PPC systems. Thanks to Anshuman Khandual for tracking the problem on PPC.
