; This test checks that 'llvm-objdump --source' works with archive files.
|
||
|
|
; The reason this test is written in .ll is that showing source code
|
||
|
|
; requires the debug data to have the source file path. Since we create
|
||
|
|
; the source file ad-hoc in this test, we don't know the path beforehand to
|
||
|
|
; create the object and archive.
