The testcase is simple:

; RUN: llc -march=hsail -print-after=dead-mi-elimination < %s 2>&1 | FileCheck %s
; CHECK: half 4.000000e+00
define half @half_const(half %in) {
entry:

  %add = fadd half %in, 0xH4400
  ret half %add

}

Though I found no backend in the trunk where a half immediate survives instruction selection and present as machine operand, thus I do not see what to put into -march for testing.
