perf jit: add source line info support (2016-02-05 12:33:09 -0300)
---------------------------------------------------------------- perf/core improvements and fixes:
User visible fixes:
- Handle spaces in file names obtained from /proc/pid/maps (Marcin Ślusarz)
New features:
- Improved support for java, using the JVMTI agent library to do jitdumps that then will be inserted in synthesized PERF_RECORD_MMAP2 events via 'perf inject' pointed to synthesized ELF files stored in ~/.debug and keyed with build-ids, to allow symbol resolution and even annotation with source line info, see the changeset comments to see how to use it (Stephane Eranian)
Documentation:
- Document mmore variables in the 'perf config' man page (Taeung Song)
Infrastructure:
- Improve a bit the 'make -C tools/perf build-test' output (Arnaldo Carvalho de Melo)
- Do 'build-test' in parallell, using 'make -j' (Arnaldo Carvalho de Melo)
- Fix handling of 'clean' in multi-target make invokations for parallell builds (Jiri Olsa)
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
---------------------------------------------------------------- Arnaldo Carvalho de Melo (4): perf build tests: Elide "-f Makefile" from make invokation perf build tests: Move the feature related vars to the front of the make cmdline perf build tests: Do parallell builds with 'build-test' perf inject: Make sure mmap records are ordered when injecting build_ids
Jiri Olsa (1): perf tools: Fix parallel build including 'clean' target
Marcin Ślusarz (1): perf tools: handle spaces in file names obtained from /proc/pid/maps
Stephane Eranian (5): perf symbols: add Java demangling support perf build: Add libcrypto feature detection perf inject: Add jitdump mmap injection support perf tools: add JVMTI agent library perf jit: add source line info support
Taeung Song (8): perf config: Document 'ui.show-headers' variable in man page perf config: Document variables for 'call-graph' section in man page perf config: Document variables for 'report' section in man page perf config: Document 'top.children' variable in man page perf config: Document 'man.viewer' variable in man page perf config: Document 'pager.<subcommand>' variables in man page perf config: Document 'kmem.default' variable in man page perf config: Document 'record.build-id' variable in man page
