2013-04-08First phase of unifying the computation of profile scale ↵Teresa Johnson22-80/+147
factors/probabilities and the actual scaling to use rounding divides... First phase of unifying the computation of profile scale factors/probabilities and the actual scaling to use rounding divides: - Add new macro GCOV_COMPUTE_SCALE to basic-block.h to compute the scale factor/probability via a rounding divide. - Change all locations that already perform rounding divides (inline or via RDIV) to use the appropriate helper: GCOV_COMPUTE_SCALE, apply_probability or combine_probabilities. - Change ipa-cp.c truncating divides to use rounding divides. - Add comments to all other locations (currently using truncating divides) to switch them to one of the helpers so they use a rounding divide. Next phase will be to replace the locations using truncating divides, marked with a comment here, into rounding divides via the helper methods. 2013-04-08 Teresa Johnson <tejohnson@google.com> * basic-block.h (GCOV_COMPUTE_SCALE): Define. * ipa-inline-analysis.c (param_change_prob): Use helper rounding divide methods.
