perf tools: Use zfree to help detect use after free bugs

2013-12-27T20:08:19+00:00

Several areas already used this technique, so do some audit to
consistently use it elsewhere.

perf tools: Default to cpu// for events v5

2013-07-12T16:53:52+00:00

When an event fails to parse and it's not in a new style format,
try to parse it again as a cpu event.

This allows to use sysfs exported events directly without //, so you can use

perf record -e mem-loads ...

instead of

perf record -e cpu/mem-loads/

perf tools: Move ltrim() to util/string.c

2013-01-24T19:40:49+00:00

As we have ltrim() implementation in builtin-script.c move it to the
more generic location of util/string.c so that it can be used from other
places.

perf probe: Move strtailcmp to string.c

2011-07-15T20:00:47+00:00

Since strtailcmp() is enough generic, it should be defined in string.c.

perf: Swap inclusion order of util.h and string.h in util/string.c

2010-04-04T14:40:42+00:00

Currently util/string.c includes headers in this order: string.h, util.h
But this causes a build error because __USE_GNU definition
is needed for strndup() definition:

	% make -j
	touch .perf.dev.null
	    CC util/string.o
	cc1: warnings being treated as errors
	util/string.c: In function ‘argv_split’:
	util/string.c:171: error: implicit declaration of function ‘strndup’
	util/string.c:171: error: incompatible implicit declaration of built-in function ‘strndup’

So this patch swaps the headers inclusion order.
util.h defines _GNU_SOURCE, and /usr/include/features.h defines
__USE_GNU as 1 if _GNU_SOURCE is defined.
