	Auto-adjust column width of perf report output to the longest occuring string length. Example: [acme@doppio pahole]$ perf report --sort comm,dso,symbol \| head -13 12.79% pahole /usr/lib64/libdw-0.141.so [.] __libdw_find_attr 8.90% pahole /lib64/libc-2.10.1.so [.] _int_malloc 8.68% pahole /usr/lib64/libdw-0.141.so [.] __libdw_form_val_len 8.15% pahole /lib64/libc-2.10.1.so [.] __GI_strcmp 6.80% pahole /lib64/libc-2.10.1.so [.] __tsearch 5.54% pahole ./build/libdwarves.so.1.0.0 [.] tag__recode_dwarf_type [acme@doppio pahole]$ [acme@doppio pahole]$ perf report --sort comm,dso,symbol -d /lib64/libc-2.10.1.so \| head -10 21.92% pahole /lib64/libc-2.10.1.so [.] _int_malloc 20.08% pahole /lib64/libc-2.10.1.so [.] __GI_strcmp 16.75% pahole /lib64/libc-2.10.1.so [.] __tsearch [acme@doppio pahole]$ Also add these extra options to control the new behaviour: -w, --field-width Force each column width to the provided list, for large terminal readability. -t, --field-separator: Use a special separator character and don't pad with spaces, replacing all occurances of this separator in symbol names (and other output) with a '.' character, that thus it's the only non valid separator.

2009-07-01	perf_counter tools: Share list.h with the kernel	Arnaldo Carvalho de Melo
	The copy we were using came from another copy I did for the dwarves (pahole) package, that came from the kernel years ago. The only function that is used by the perf tools and that isn't in the kernel is list_del_range, that I'm leaving in the perf tools only for now.

2009-07-01	perf_counter tools: Share rbtree.with the kernel	Arnaldo Carvalho de Melo
	The tools/perf/util/rbtree.c copy already drifted by three csets: 4b324126e0c6c3a5080ca3ec0981e8766ed6f1ee 4c60117811171d867d4f27f17ea07d7419d45dae 16c047add3ceaf0ab882e3e094d1ec904d02312d So remove the copy and use the lib/rbtree.c directly, sharing the source code while still generating a separate object file, since tools/perf uses a far more agressive -O6 switch.
