Preserving Call to Intrinsic function
...problem currently is that LLVM eliminated the second call and copied
the result from the first call into a new set of registers. Is there is a
way to force LLVM to generate two explicit calls to a builtin function. The
builtin takes in an integer type, and also returns back an integer type:
def int_XX : GCCBuiltin<"__builtin_XX">, Intrinsic<[llvm_i32_ty],
[llvm_i32_ty]>;
Is there some flag that I'm missing? Your help will be really appreciated.
Best Regards,
Kumail Ahmed
