* Add a Python library to read /proc on Linux.dmikurube@chromium.org2013-11-294-243/+20
| | | | | | | | | | | | It also moves tools/find_runtime_tools/proc_maps.py into tools/linux/procfs.py.

* Estimates a path in host from a corresponding path in Android device.dmikurube@chromium.org2013-05-201-5/+5
| | | | | | | | | | | | | | | For Android, dmprof.py should find symbol information from binaries in the host instead of the Android device because dmprof.py doesn't run on the Android device. They are in different directories. This change estimates a path in the host from a corresponding path in the Android device.

* Breakdown memory usage by source file names in dmprof.dmikurube@chromium.org2013-04-092-69/+90
| | | | | | | | | | | | dmprof has classified memory usage by pattern-matching with function names. It adds another classification by pattern-matching with source file names.

* Add hints to find source file names from runtime virtual addresses.dmikurube@chromium.org2013-04-033-0/+230
| | | | | | | | | | | | | | | | | prepare_symbol_info.py collected symbol and elf mapping information from binaries. This patch adds another set of hints to find source file names from DWARF .debug_line information with readelf. reduce_debugline.py picks up only address ranges from the original readelf output since the original output is too large. See the test how it works.
