--- Comment #3 from Andrew Fish <afish at apple.com> ---
When we use the clang assembler we see the relative offset shrink due to
function B() getting stripped. It has the same "e8 e8 ff ff ff  calll  0x1f7e"
in the object prior to linking.

~/work/Compiler/link>lldb a.out
(lldb) target create "a.out"
Current executable set to 'a.out' (i386).
(lldb) dis -b -n IoReadFifo8
a.out`IoReadFifo8:
a.out[0x1f89] <+0>:  57              pushl  %edi
a.out[0x1f8a] <+1>:  e8 f1 ff ff ff  calll  0x1f80                    ;
SevNoRepIo
a.out[0x1f8f] <+6>:  85 c0           testl  %eax, %eax
a.out[0x1f91] <+8>:  5f              popl   %edi
a.out[0x1f92] <+9>:  c3              retl
