[DebugInfo] Fix potential CU mismatch for SubprogramScopeDIEs.
|
||||
|
||||
In constructAbstractSubprogramScopeDIE there can be a potential mismatch
|
||||
between `this` and the CU of ContextDIE when a scope is shared between
|
||||
two DISubprograms belonging to a different CU. In that case, `this` is
|
||||
the CU that was specified in the IR, but the CU of ContextDIE is that of
|
||||
the first subprogram that was emitted. This patch fixes the mismatch by
|
||||
looking up the CU of ContextDIE, and switching to use that.
|
||||
|
||||
This fixes PR35212 (https://bugs.llvm.org/show_bug.cgi?id=35212)
|
||||

||||
