Description Andrew Lenharth 2006-07-06 10:21:49 PDT 
Legalize doesn't legalize the arguments to an inline asm call.  see
test/Regression/CodeGen/Alpha/2006-07-03-ASMFormalLowering.ll for an example.  I
would think that a similar example (function consisting of only a call to an
inline asm block) in other archs would show the same problem.

What am I missing here?

$ llvm-as < 2006-07-03-ASMFormalLowering.ll | llc -march=alpha
 Cannot yet select: 0x8603da0: i64,i64,ch = formal_arguments 0x8603cf0, 0x8603d50, 0x8603d50
Abort

This looks like you haven't implemented support for formal arguments yet.  ?
