llvm dev - Mar 2015 - [LLVMdev] Does llvm intrinsic function allow "complicated" arguments?

Hi,guys:

I am interested to use the IR information to modify the AST of the source code
But I am not sure whether the LLVM support or not.

Thanks,
yao

I think your question needs a bit more information - what do you want
to modify in the AST, based on what IR information? Overall, what are
you trying to achieve? [Maybe there is a "better" way to do that]

Hi Guys, 

I see an intrinsic function call like this "call float
@ir.sample_complex.f32(float a, int bitcast (i16  337203 to i32) , i32 1, <2
x float> %62, float %61)  “,
Then I got trouble to process the third operand "int bitcast (i16  337203
to i32)”, the second operand I got is “constant 337203”.

I think something is messed up,  but the getOperand(i) is llvm core function. So
I suspect the above intrinsic call is legal or not?

any suggestions?
