Seems we were setting the base address on the wrong DwarfCompileUnit object so it wasn't being used when generating the ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236377 91177308-0d34-0410-b5e6-96231b3b80d8

; Test the emission of gmlt-like inlining information into the skeleton unit.
|
|
; This allows inline-aware symbolication/backtracing given only the linked
|
|
; executable, without needing access to the .dwos.
|
|
|
|
; A simple example of inlining generated with clang -gsplit-dwarf
|
|
|
|
; A member function is used to force emission of the declaration of the
|
|
; function into the .dwo file, which may be shared with other CUs in the dwo ;
|
|
; under fission, but should not be shared with the skeleton's CU. This also
|
|
; tests the general case of context emission, which is suppressed in gmlt-like
|
|
; data.
|
|
|
|
; Include a template just to test template parameters are not emitted in
|
|
; gmlt-like data.
|
|
|
|
; And some varargs to make sure DW_TAG_unspecified_parameters is not emitted.
|
|
|
|
; And a using declaration in a nested lexical_block... because that shouldn't
|
|
; be emitted either.
|
|
|
|
; Minor complication: after generating the LLVM IR, it was manually edited so
|
|
; that the 'f1()' call from f3 was reordered to appear between the two inlined
|
|
; f1 calls from f2. This causes f2's inlined_subroutine to use DW_AT_ranges,
|
|
; thus exercising range list generation/referencing which was buggy.
