Parts of wtf/Assertions.h are available in non C++ contexts and in some downstream consumers of WebKit are not compiled with GNU extensions, so these parts must not use 'asm' but instead '__asm__'. This problem has become apparent due to the use of clang modules which compile the entire file to an AST and thus reveal compilation errors even if these macros are not actually used.
