More changes for HPHP to help make it clang friendly
~~~hphp/compiler/expression/constant_expression.h
~~~hphp/compiler/expression/function_call.h
rfind returns a size_t/unsigned int
~~~hphp/runtime/base/server/http_protocol.cpp
Switched to std::to_string. Assuming [] was not intended here
~~~hphp/runtime/base/ref_data.h
These fields were accessed in a public manner, assuming public was intended
instead of private
~~~hphp/runtime/base/variable_serializer.cpp
Switched to using [] and & to make clang happy. Assuming this was to either
take or drop the first char.
~~~hphp/runtime/ext/asio/asio_external_thread_event_queue.h
~~~hphp/runtime/ext/asio/asio_external_thread_event_queue.cpp
Cast which performs the conversions of a reinterpret_cast is not
allowed in a constant expression. This is been moved to a macro as a temporary
fix.
+++hphp/runtime/ext/ext_misc.cpp
Added std::atomic to supress warnings
~~~hphp/runtime/vm/jit/simplifier.cpp
Chosen constructor is explicit in copy-initialization
~~~hphp/runtime/vm/jit/translator-asm-helpers.S
Ambiguous instructions require an explicit suffix
Changed cmp to cmpl
~~~hphp/runtime/vm/jit/translator-x64-helpers.cpp
Clang does not support global register variables
+++hphp/runtime/vm/unwind.cpp
describeFault was only used when DEBUG or USE_TRACE was defined
~~~hphp/runtime/vm/verifier/check_unit.cpp
Made fmt pointer const to avoid string format issues/warnings
~~~hphp/util/stack_trace.cpp
Clang does not support variable-length arrays.
Uniqe_ptr is used instead to take advantage runtime-sized arrays, a
restriced form of variable-length arrays
~~~hphp/util/thread_local.h
Clang seems to be supporting the __thread attribute, or at the very least
it is not complaining about it.
~~~hphp/util/tiny_vector.h
Clang does not like the flexible array here, since T is not always POD.
I have reimplemented the array here by just sticking one value in the struct
and calculating the offset from its address manually.
Alterinatively, we could change the the non-POD types to be pointers, or
we could edit their implemenations.
+++hphp/util/util.h
Created a template for the union,
A function declared with the constexpr specifier cannot contain
type declarations that do not define classes or enumerations
+++hphp/runtime/vm/jit/x64-util.h
Added a TODO
The way hphp/runtime/vm/jit/x64-util.h is currently implemented, it only
works if USE_GCC_FAST_TLS is defined
AsioExternalThreadEvent::unserialize() may legally throw PHP exceptions.
When that happens, construction of PHP exceptions reenters VM, surprised
flag is checked and pending C++ exceptions may be thrown.
Let's make sure the queue of received events in runUntil() is not lost.
Move this responsibility to the AsioExternalThreadEventQueue.
External thread event queueing logic is big enough that it deserves its
own class. Move the code and rename members to better reflect the
underlying operations. Implementation is otherwise unchanged.
