So this is likely because yarr jit is enabled (because llint cloop is enabled) and the code in VM.cpp assumes that assembler is on if yarr jit is on.

If i leave assembler enabled on sparc64, it blows horribly:

./Source/JavaScriptCore/assembler/MacroAssembler.h:66:2: error: #error "The MacroAssembler is not supported on this platform."
 #error "The MacroAssembler is not supported on this platform."

This is just https://bugs.webkit.org/show_bug.cgi?id=113638 over and over again
