[rohitrao (ping after 24h), 2016/11/07 23:16:13]

Is this being changed from "inline __attribute__((always_inline))" to just
"inline"?

[palmer, 2016/11/07 23:29:51]

No, no change. compiler_specific.h says:

#if COMPILER_GCC && defined(NDEBUG)
#define ALWAYS_INLINE inline __attribute__((__always_inline__))
#elif COMPILER_MSVC && defined(NDEBUG)
#define ALWAYS_INLINE __forceinline
#else
#define ALWAYS_INLINE inline
#endif

build/build_config.h shows only those 2 compilers as normal, and COMPILER_GCC
defined if __GNUC__ is defined, so I am assuming that this covers Clang too.

Yeah, clang defines __GNUC__:

$  clang -dM -E - < /dev/null|grep GNUC
#define __GNUC_MINOR__ 2
#define __GNUC_PATCHLEVEL__ 1
#define __GNUC_STDC_INLINE__ 1
#define __GNUC__ 4

     static const WebCore::LChar* name = (const WebCore::LChar*)arguments; \
     static const size_t name##Length = (arraysize(arguments) - 1); \
