2013-04-29This patch fixes PR bootstrap/57077.Teresa Johnson7-22/+46
This patch fixes PR bootstrap/57077. Certain new uses of apply_probability are actually scaling the counts up, and the scale factor should not be treated as a probability as the value may exceed REG_BR_PROB_BASE. One example (from the PR) is when scaling counts up in LTO when merging profiles. Another example I found when preparing the patch to use the rounding divide in more places is when inlining COMDAT functions. Add new helper function apply_scale that does the scaling without the probability range check. I audited the new uses of apply_probability and changed the calls as appropriate. 2013-04-29 Teresa Johnson <tejohnson@google.com> PR bootstrap/57077 * basic-block.h (apply_scale): New function.
