This diff removes LVariableTable, RVariableTable, and getHphpBinaryType().
It also consolidates some of the include logic that was spread across
multiple files.
Xbox threads can now release memory after each request. Also
gives cleaner semantics as Xbox requests dodn't have to be careful
about not modifying global state.
This is the last step to being able to get rid of the c++ code
gen in hphp. "make -Chphp/system" is now a no-op.
I'll rip out the actual c++ generating code as a separate diff.
This basically targetted symbols.php, and Globals, but ended up
killing a lot more. I could keep adding more and more, but
this seems like a good point to stop and continue with
another diff.
This reduces CPU instruction count by about 0.2%, has negligible impact on other metrics. Implementation has been changed a but upon discussion with @mwilliams to account for circular destruction. The question remains open whether this should be in before or after rooting out hphpc, but on the other hand we gotta do what we gotta do to move forward.
On the back burner I've been working on a diff to pull out of some of
the old VM-incompatible machinery for invoking functions/methods and for
creating object. Along the way I noticed some bugs, so I figured I'd fix
them first in a separate diff to make review easier.
g++-4.7.1 treats "FOO"bar as a c++-11 literal operator, even
if bar is a macro with an expansion such as "BAR" - so add a space
after the quote (this seems like a bug, and I fixed a bunch of these
a while ago, but we just added a slew of PRI*64 macros which break
under 4.7.1).
Also, it warned that "explicit by-copy capture of 'this' redundant"
for a lambda declared [=, this] - so I removed the this.
We also needed more than the 60 levels of template expansion that was
allowed by the makefile.
Per @mwilliams' suggestion, this is the first stage in a staggered approach to replacing int64 with int64_t. More precisely I inserted "typedef ::int64_t int64;" in util/base.h and dealt with the consequences.
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.
