            Bug ID: 39993
           Summary: LLVM generates wrong MSP430 code for indirect input
                    constraints
           Product: new-bugs
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs
          Assignee: unassignedbugs at nondot.org

Since r346948, LLVM generates wrong MSP430 code for indirect input 
constraints inline assembly.

For example, for the following IR snippet

  target triple = "msp430-unknown-unknown-elf"

  define void @f() {
  entry:
    call void asm sideeffect "mov r1, $0", "*m"(i8* inttoptr (i16 256 to i8*))
    ret void
  }

the inline assembly is wrongly translated into

        mov r1, 256(r2)

instead of into

        mov r1, &256
