2013-11-05tools/perf/build: Fix detection of non-core featuresDavid Ahern1-5/+5
feature_check needs to be invoked through call, and LDFLAGS may not be set so quotes are needed. Thanks to Jiri for spotting the quotes around LDFLAGS; that one was driving me nuts with the upcoming timerfd feature detection.

2013-10-14tools/perf/build: Pass through DEBUG parameterIngo Molnar1-5/+2
Arnaldo reported that 'make DEBUG=1' does not work anymore. The reason is that 'Makefile' only passes it through to 'Makefile.perf' via the environment, but 'Makefile.perf' checks that it's a command line option: ifeq ("$(origin DEBUG)", "command line") PERF_DEBUG = $(DEBUG) endif So pass it through properly, and also clean up DEBUG parameter handling while at it and fix a couple of annoyances: - DEBUG=0 used to be interpreted as 'debugging on'. Turn it into 'debugging off' instead. - Same was the case for 'DEBUG=' - turn that into debug-off as well. - Pass in just a clean, sanitized 'DEBUG' value and get rid of the intermediate, unnecessary PERF_DEBUG variable.

2013-10-09perf tools: Implement addr2line directly using libbfdRoberto Vitillo1-0/+4
When the srcline sort key is used , the external addr2line utility needs to be run for each hist entry to get the srcline info. This can consume quite a time if one has a huge perf.data file.
