I tried to emit IR for a function that returns the sum between an signed char and a double in C++, just to see how Clang handles type implicit casting. Can you explain me why Clang converted the char type into a 32-bit integer type before casting it to a floating point? Can a sitofp i8 %3 to double be done or is it wrong? define i32 @_Z5sumad(i8 signext %x, double %y) #0 { %1 = alloca i8,
