When object support was first added to HHVM, a class named "Instance"
was introduced (deriving from ObjectData) to represent instances of user
defined classes. Since then, things have evolved and HPHPc and HPHPi have
been retired, and now there really is no needed to have ObjectData and
Instance be separate classes anymore.
As a first step towards merging ObjectData and Instance together, this diff
puts their definitions in the same .h file and puts their implementations
in the same .cpp file. A few small changes were necessary to fix issues
with cyclical includes: (1) Repo/emitter related parts of class.cpp and
class.h were moved to class-emit.cpp and class-emit.h; (2) the contents of
"vm/core_types.h" was moved to "base/types.h"; and (3) a few functions that
didn't appear to be hot were moved from .h files and the corresponding .cpp
files.
I noticed that directorty structure of hphp/system was a bit scattered, so
I consolidated things to reduce the total number of folders and to put
related things together with each other.
This diff moves the contents of "hphp/system/classes_hhvm" into
"hphp/system", it moves the contents of "hphp/system/lib" into
"hphp/system", moves "hphp/idl" to "hphp/system/idl", and moves the
contents of "hphp/system/globals" into "hphp/system/idl".
I was learning from @jdelong and he said that you should use
double quotes for local includes and angle brackets for library
includes. I asked why our code was the way it was, and he said he wanted
to clean it up. I beat him to it :)
Conflicts:
hphp/runtime/base/server/admin_request_handler.cpp
hphp/runtime/vm/named_entity.h
This func took 2 params and ignored the second one. While I was there I made the functions call eachother. Hopefully inlining is smart enough to let me clean this code.
I got a bit carried away, but I think this is better.
This change is mostly for FB internal organizational reasons.
Building is not effected beyond the fact that the target now
lands in hphp/hhvm/hhvm rather than src/hhvm/hhvm.
