perf session: Make ordered_events reusable

2016-04-14T11:57:54+00:00

ordered_events__free() leaves linked lists and timestamps not cleared,
so unable to be reused after ordered_events__free(). Which is inconvenient
after 'perf record' supports generating multiple perf.data output and
process build-ids for each of them.

Use ordered_events__reinit() for this.

perf evsel: Move some methods from session.[ch] to evsel.[ch]

2016-04-13T13:11:52+00:00

Those were converted to be evsel methods long ago, move the
source to where it belongs.

perf evsel: Allow unresolved symbol names to be printed as addresses

2016-04-12T01:18:24+00:00

The fprintf_sym() and fprintf_callchain() methods now allow users to
change the existing behaviour of showing "[unknown]" as the name of
unresolved symbols to instead show "[0x123456]", i.e. its address.

The current patch doesn't change tools to use this facility, the results
from 'perf trace' and 'perf script' cotinue like:

70.109 ( 0.001 ms): qemu-system-x8/10153 poll(ufds: 0x7f2d93ffe870, nfds: 1) = 0 Timeout
                                   [unknown] (/usr/lib64/libc-2.22.so)
                                   [unknown] (/usr/lib64/libspice-server.so.1.10.0)
                                   [unknown] (/usr/lib64/libspice-server.so.1.10.0)
                                   [unknown] (/usr/lib64/libspice-server.so.1.10.0)
                                   start_thread+0xca (/usr/lib64/libpthread-2.22.so)
                                   __clone+0x6d (/usr/lib64/libc-2.22.so)

The next patch will make 'perf trace' use the new formatting.

perf evsel: Introduce fprintf_callchain() method out of fprintf_sym()

2016-04-12T01:18:18+00:00

In 'perf trace' we're just interested in printing callchains, and we
don't want to use the symbol_conf.use_callchain, so move the callchain
part to a new method.

perf evsel: Rename print_ip() to fprintf_sym()

2016-04-12T01:18:17+00:00

As it receives a FILE, and its more than just the IP, which can even be
requested not to be printed.

For consistency with other similar methods in tools/perf/, name it as
perf_evsel__fprintf_sym() and make it return the number of bytes
printed, just like 'fprintf(3)'
