From a1d44b9acdf7b2820ef762846150b4d13b84e075 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 23 May 2012 21:47:51 -0300 Subject: perf evlist: Explicititely initialize input_name It was a global variable, so it was initialized, implicitely, to zero by being placed in the bss. Now it is just a local variable that is then passed to the __cmd_evlist routine, so it must be explicitely set to NULL. The problem manifested on a Fedora 17 system, using: gcc version 4.7.0 20120507 (Red Hat 4.7.0-5) (GCC) But not on several other systems, by luck.

Fix it by just freeing and setting counter->name to NULL, this way event_name() when called afterwards, will find the right counter name and cache it again. Found while trying 'cycles:pp' on a machine were :pp couldn't be honoured. Probably the best fallback here is to tell the user that that level of precision is not available on the PMU and then go removing 'p', levels of precision till we get to play 'cycles' and if even that fails, _then_ get to 'cpu-clock'. But that is the matter for another patch, this one just needs to fix the caching issue, which in the end will show 'cpu-clock' when tools ask for the event name being used, which clarifies things for the user, that will see that 'cycles:pp' or whatever not support event is not being used, some sort of fallback happened.

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.
