	11 Description:

	12 Implementation of instrumentation functions for use with gcc's

	13 -finstrument-functions option.

	14

	15 Local Modifications:

	16 09/07/2011: Original unmodified version of code added to third_party

	17

	18 09/08/2011: cyg-profile.c was removed and replaced with the cyg-profile.cc file.

	19 The style has been changed to fit Google's style guide. Logging and format

	20 changed to log only first entry of a function. Logs virtual address of code

	21 section which contains profiled code, and logs timestamps of calls. The

	22 implementation was also made thread-safe with the use of stdlib sets and a

	23 pthread mutex.

	24

	25 01/23/2012: Android: enable profiling on first __cyg_profile_func_enter() call.

	26 This is useful to profile the large number of static initializers used

	27 by Chromium on this platform.

	28

	29 07/03/2012:

	30 Moving third_party/cygprofile/ to base/android/third_party/cygprofile/. This

	31 implementation is currently only being used by Android and is so different from

	32 the original version that it makes more sense to move to base/android/. There is

	33 yet another implementation of cygprofile in //tools/cygprofile/ which is being

	34 used by Chromium, that is also different from the open-source version, and

	35 different from the version used by Android.

	36

	37 07/04/2012: Renaming base/android/third_party/cygprofile/ to cygprofile_startup

	38 since this version only collects profiling information from the first time a

	39 function is run. This has been used to investigate ways to improve Chrome for

	40 Android startup time.
