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
