This fixes part of the issue described in PR gcov-profile/54487 where there were warnings about mismatches due to slight differences in the merged histograms in different object files. This can happen due to the truncating integer division in the merge routine, which could result in slightly different histograms when summaries are merged in different orders. 2012-09-07 Teresa Johnson <tejohnson@google.com> PR gcov-profile/54487 * libgcc/libgcov.c (gcov_exit): Avoid warning on histogram differences.

Enhances the gcov program summary by adding a histogram of arc counter entries. This is used to compute working set information in the compiler for use by optimizations that need information on hot vs cold counter values or the rough working set size in terms of the number of counters.

collect... This patch adds functionality to libgcov to enable user applications to collect profile data only in regions of interest. This is useful, for example, to collect profile data from a long-running server only during the time when it is serving requests. Specifically, the new routines __gcov_reset will clear all profile counters to zero and __gcov_dump will write out the profile information collected so far. A global variable is used to prevent writing out the profile a second time during exit. 2012-05-08 Teresa Johnson <tejohnson@google.com> * libgcc/libgcov.c (gcov_clear, __gcov_reset): New functions.
