2012-09-04Adding change log entries for r190952:Teresa Johnson1-0/+8
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. Each working set data point is the minimum counter value and number of counters required to reach a given percentage of the cumulative counter sum across the profiled execution (sum_all in the program summary). 2012-09-04 Teresa Johnson <tejohnson@google.com> * libgcc/libgcov.c (struct gcov_summary_buffer): New structure.

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.
