perf annotate: Add missing powerpc triplet

2017-06-05T17:18:02+00:00

On an Ubuntu xenial system, 'perf annotate' says to install powerpc
objdump on a system that already has binutils-powerpc-linux-gnu
installed.  Make perf aware of the missing triplet for the
powerpc-linux-gnu target.

perf tools: Remove needless includes from cache.h

2016-07-12T18:19:58+00:00

The cache.h header doesn't use any of the definitions in some of the
headers it includes, ditch them and fix the fallout, where files were
getting stuff they needed just because they were including it, sometimes
not using what it really exports at all.

perf tools: Add more toolchain triplets

2016-06-27T17:31:41+00:00

Add few more triplets based on Fedora and Ubuntu binutils (cross tools).

Before applying patch on x86:

  ( Install binutils-powerpc64-linux-gnu.x86_64 )
  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc \
      --objdump powerpc64-linux-gnu-objdump

After applying patch on x86:

  $ perf report -i perf.data.powerpc --vmlinux vmlinux.powerpc

I.e. it will find the right objdump from the environment data recorded
in the perf.data file + these triplets.

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: 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.
