perf env: Rename some leftovers from rename to perf_env

2015-09-14T15:50:20+00:00

In ce80d3bef9ff ("perf tools: Rename perf_session_env to perf_env") we
forgot to rename a few functions to the "perf_env" prefix, do it now.

perf tools: Rename perf_session_env to perf_env

2015-08-28T17:53:55+00:00

As it is not necessarily tied to a perf.data file and needs using in
places where a perf_session is not required.

perf tools: Add arm64 triplets

2014-08-15T13:40:11+00:00

Adds the triplet used for arm64 by Android. Others will want to add
their own later.

perf tools: Introduce zfree

2013-12-27T18:17:00+00:00

For the frequent idiom of:

   free(ptr);
   ptr = NULL;

Make it expect a pointer to the pointer being freed, so that it becomes
clear at first sight that the variable being freed is being modified.

perf tools: Don't try to lookup objdump for live mode

2012-11-08T20:26:52+00:00

Arnaldo reported that annotation during perf top resulted in a segfault.
It was because the env->arch was NULL and we don't set it for a live
session.  In fact, no need to look up objdump in this case since we can
use system's default (native) objdump.

perf tools: Use normalized arch name for searching objdump path

2012-11-05T17:03:58+00:00

David reported that perf report for i686 target data on x86_64 host
failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need
to do it at all.  To prevent similar artifacts, normalize arch name when
comparing host and file architectures.

perf tools: Try to find cross-built objdump path

2012-10-24T16:20:11+00:00

As we have architecture information of saved perf.data file, we can try
to find cross-built objdump path.

The triplets include support for Android (arm, x86 and mips
architectures).
