I'll try to run through the scenario: 64-bit register type target (all registers have 64 bits). all 32-bits are getting promoted to 64-bit integers Problem: MUL on i32 is getting promoted to MUL on i64 MUL on i64 is getting expanded to a library call in compiler-rt the problem is that MUL32 gets promoted and then converted into a subroutine call because it is now type i64, even though
