2012-10-06perf event: No need to create a thread when handling PERF_RECORD_EXITArnaldo Carvalho de Melo9-21/+39
When we were processing a PERF_RECORD_EXIT event we first used machine__findnew_thread for both the thread exiting and for its parent, only to use just the thread struct associated with the one exiting, and to just delete it. If it existed, i.e. not created at this very moment in machine__findnew_thread, it will be moved to the machine->dead_threads linked list, because we may have hist_entries pointing to it, but if it was created just do be deleted, it will just sit there with no references at all. Use the new machine__find_thread() method so that if it is not there, we don't create it. As a bonus the parent thread will also not be created at this point. Create process_fork() and process_exit() helpers to use this and make the builtins use it instead of the generic process_task(), ditched by this patch.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare1-1/+1
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.

2012-10-02perf inject: Remove static variablesArnaldo Carvalho de Melo1-34/+38
We want to reduce the impact that each of the builtins has on perf as a whole, so use the superclassing of perf_tool mechanizm to move its config knobs to the stack, so that only if we use that tool, its impact will be felt. In this case is more about consistency, as the impact of this tool is minimal.

2012-10-02perf inject: Remove unused 'input_name' static varArnaldo Carvalho de Melo1-2/+1
If we ever want to allow inject to work with something other than stdin, we can put it back, but so far it is completely unused, so ditch it.

2012-10-02perf trace: Use evsel->handler.funcArnaldo Carvalho de Melo1-45/+87
I.e. we don't need to resolve the evsel via the id and then check if it is this or that event, just stash the right handler at evsel creation time, then use evsel->handler.func() straight away.
