tools lib traceevent: Do not call warning() directly

2014-04-14T10:55:00+00:00

The patch 3a3ffa2e82205 ("tools lib traceevent: Report better error
message on bad function args") added the error message but it seems
there's no reason to call warning() directly.

So change it to do_warning_event() to provide event information too.

tools lib traceevent: Print event name when show warning if possible

2014-04-14T10:55:00+00:00

It's sometimes useful to know where the parse failure was occurred.  Add
do_warning_event() macro to see the failing event.

It now shows the messages like below:

  $ perf test 5
   5: parse events tests                                     :  Warning: [kvmmmu:kvm_mmu_get_page] bad op token {

tools/liblockdep: Add proper versioning to the shared obj

tools/liblockdep: Ignore asmlinkage and visible

2014-04-01T15:46:09+00:00

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added
asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep.

Since we don't need asmlinkage in liblockep, just ignore it.

tools/liblockdep: Use realpath for srctree and objtree

2014-02-27T02:22:01+00:00

If BUILD_SRC or CURDIR contains tailing '/', the file names passed to gcc will
contain '//'. It will be contained .o's in debuginfo, then confuse debugedit:

https://bugzilla.redhat.com/show_bug.cgi?id=304121

This patch uses realpath command to makesure potential tailing '/'s are removed.

tools/liblockdep: Add include directory to allow tests to compile

2014-02-27T02:21:56+00:00

All of the programs in the tests directory require the
liblockdep/mutex.h header in order to compile. Add the include directory
to the compiler options so that the tests can be built with the provided
Makefile.
