; MD5 checksums provided by IR should be passed through to asm.
|
|
; They'll be emitted to an object file only for DWARF 5 or later.
|
|
;
|
|
; Note that on Darwin for DWARF 4 or earlier, the line table version is clamped
|
|
; to version 2. However that doesn't affect the output checked in this test.
