Hi Tao,<br>
<br>
The method PSAdaptiveSizePolicy::compute_generation_free_space()
is a monster method. It does all kinds of things. Its comment kind
of reveals this:<br>
<br>
339 // Calculates optimial free space sizes for both the old
and young<br>
340 // generations. Stores results in _eden_size and
_promo_size.<br>
341 // Takes current used space in all generations as input, as
well<br>
342 // as an indication if a full gc has just been performed,
for use<br>
343 // in deciding if an OOM error should be thrown.<br>
<br>
So, I think that if we should rename it we should give it a name
that reflects this. The current name is not good, but I don't
think compute_generations_free_space() is much better. I would
suggest to either leave it unchanged or change to a more
descriptive name.<br>
<br>
Maybe gether_adapitve_size_statistics() or
update_adaptive_size_values(). Not very happy with those names
either, but at least they indicate that ther eis more than just
free space calculations in there.<br>
<br>
<br>
In psGCAdaptivePolicyCounters.hpp you updated a method name that
has been commented out. I would suggest removing it rather than
updating it.<br>
<br>
Thanks,<br>

Why this change from resize_old_gen() to<br>
resize_tenured_gen()? There are many<br>
variable names and comments referring to<br>
"old gen" still in ParallelScavengeHeap.<br>

8007762: Rename a bunch of methods in size policy across

changeset:<br>
The motivation of this change is associated with CR
7098155 (<a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="https://jbs.oracle.com/bugs/browse/JDK-7098155">https://jbs.oracle.com/bugs/browse/JDK-7098155</a>).
For this, we need to split
compute_generations_free_space into two routine (one for
compute_eden_space_size and the other for
compute_tenured_generation_free_space) in order to save
some overhead when we want to compute only one of the
two. The next step is to split
PSAdaptiveSizePolicy::compute_generations_free_space(),
which will be resolved in CR 8007763.<br>
<br>
To unify the naming, a bunch of routines are renamed
here.<br>
(1) compute_*: <br>
compute_survivor_space_size_and_threshold() <br>
compute_generations_free_space() =
compute_eden_space_size() +
compute_tenured_generation_free_space()<br>
(2) resize_*_gen: <br>
resize_young_gen() <br>
resize_tenured_gen() <br>
(3) rename judging routine resize_geneneration() to
need_resize() to avoid ambiguity<span style="color:
