This is a wild guess, but I think your asm code is getting placed in a
random section depending on the other options. Try adding a ".text"
statement in the function definition below:

DFGOperations.cpp:

asm (
".globl getHostCallReturnValue\n"
".hidden getHostCallReturnValue\n"
"getHostCallReturnValue:\n"
    "mov -40(%r13), %r13\n"
    "mov %r13, %rdi\n"
    "jmp getHostCallReturnValueWithExecState\n"
);
