DAVEM TPF Grant#2 September 2014 report
Message ID:

The main things I worked on this month were:

* finished off making the op_private OP flags and data be auto-generated
  from a single consistent source.

* I started to investigate how the allocation and growing of strings (in
  Perl_sv_grow()) interacts (sometimes badly) with COW and the underlying
  malloc() library implementation

* reviewing, discussing, fixing up and applying Syber's method call
  optimisation work
