Revised patch to ensure that histograms from the profile summary are streamed...
Revised patch to ensure that histograms from the profile summary are streamed
through the LTO files so that the working set can be computed for use in
downstream optimizations.
2012-11-30 Teresa Johnson <tejohnson@google.com>
* lto-cgraph.c (output_profile_summary): Stream out sum_all
and histogram.
(input_profile_summary): Stream in sum_all and histogram.
(merge_profile_summaries): Merge sum_all and histogram, and
change to use RDIV.
(input_symtab): Call compute_working_sets after merging
summaries.
* gcov-io.c (gcov_histo_index): Make extern for compiler.
* gcov-io.h (gcov_histo_index): Ditto.
* profile.c (compute_working_sets): Remove static keyword.
* profile.h (compute_working_sets): Ditto.
* Makefile.in (lto-cgraph.o): Depend on profile.h.
