While I was working on the TestCodeRun refactor I found two tests about Tainted code. I looked into it and coulnd't get HHVM to compile with TAINTED=1. Then I checked and none of the extension functions we exposed about tainting were used in WWW. Scratching my head I asked, @srenfro and @jdelong, who thought it was dead. So I killed this zombie.
unserialize() and call_user_func_array() were straightforward. They were
called from all over the runtime, but I renamed those implementations
and codemodded the runtime.
The is_* functions were only ever being called by the CVarRef signature,
so I deleted all the other ones (same for f_gettype). Only some of the
is_* functions were being called from the runtime, so I made inline
versions of those without the f_ prefix.
This diff removes LVariableTable, RVariableTable, and getHphpBinaryType().
It also consolidates some of the include logic that was spread across
multiple files.
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 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.
