This patch adds a --jit/-j option to perf inject.
This options injects MMAP records into the perf.data file to cover the
jitted code mmaps. It also emits ELF images for each function in the
jidump file. Those images are created where the jitdump file is. The
MMAP records point to that location as well.
Typical flow:
$ perf record -k mono -- java -agentpath:libpjvmti.so java_class
$ perf inject --jit -i perf.data -o perf.data.jitted
$ perf report -i perf.data.jitted
Note that jitdump.h support is not limited to Java, it works with any
jitted environment modified to emit the jitdump file format, include
those where code can be jitted multiple times and moved around.
The jitdump.h format is adapted from the Oprofile project.
The genelf.c (ELF binary generation) depends on MD5 hash encoding for
the buildid. To enable this, libssl-dev must be installed. If not, then
genelf.c defaults to using urandom to generate the buildid, which is not
ideal. The Makefile auto-detects the presence on libssl-dev.
This version mmaps the jitdump file to create a marker MMAP record in
the perf.data file. The marker is used to detect jitdump and cause perf
inject to inject the jitted mmaps and generate ELF images for jitted
functions.
In V8, the following fixes and changes were made among other things:
- the jidump header format include a new flags field to be used
to carry information about the configuration of the runtime agent.

- Fix mmap pgoff: MMAP event pgoff must be the offset within the ELF file
at which the code resides.
Contributed by: Adrian Hunter <adrian.hunter@intel.com>
- Fix ELF virtual addresses: perf tools expect the ELF virtual addresses of dynamic
objects to match the file offset.
Contributed by: Adrian Hunter <adrian.hunter@intel.com>
- JIT MMAP injection does not obey finished_round semantics. JIT MMAP injection injects all
MMAP events in one go, so it does not obey finished_round semantics, so drop the
finished_round events from the output perf.data file.

To make sure the mmap records are ordered correctly and so that the
correct especially due to jitted code mmaps.
We cannot generate the buildid hit list and inject the jit mmaps (will
come right after this patch) in at the same time for now.

We broke interval data displays with commit:
3f416f22d1e2 ("perf stat: Do not clean event's private stats")
This commit removed stats cleaning, which is important for '-r' option
to carry counters data over the whole run. But it's necessary to clean
it for interval mode, otherwise the displayed value is avg of all
previous values.
Before:
$ perf stat -e cycles -a -I 1000 record
# time counts unit events
1.000240796 75,216,287 cycles
2.000512791 107,823,524 cycles
$ perf stat report
# time counts unit events
1.000240796 75,216,287 cycles
2.000512791 91,519,906 cycles
Now:
$ perf stat report
# time counts unit events
1.000240796 75,216,287 cycles
2.000512791 107,823,524 cycles
Notice the second value being bigger (91,.. < 107,..).
This could be easily verified by using perf script which displays raw
stat data:
$ perf script
CPU THREAD VAL ENA RUN TIME EVENT
0 -1 23855779 1000209530 1000209530 1000240796 cycles

2 -1 15835415 1000226695 1000226695 1000240796 cycles

3 -1 7634472 2000544108 2000544108 2000512791 cycles
The sum of the first 4 values is the first interval aggregated value:
23855779 + 33340397 + 15835415 + 2184696 = 75,216,287
The sum of the second 4 values minus first value is the second interval
aggregated value:
97014312 + 46121497 + 32269530 + 7634472 - 75216287 = 107,823,524

Adding struct perf_hpp_list argument to following helper functions:
void perf_hpp__setup_output_field(struct perf_hpp_list *list);
void perf_hpp__reset_output_field(struct perf_hpp_list *list);
void perf_hpp__append_sort_keys(struct perf_hpp_list *list);
so they could be used on hists's hpp_list.
