[LLVMdev] Why variables get "optimized away" after the last use in unoptimized code?
...>
Looking at the debug records, I don't see what is wrong, for example:
call void @llvm.dbg.declare(metadata !{%struct.Object* %1}, metadata
!73), !dbg !74
!73 = metadata !{i32 786689, metadata !63, metadata !"this", metadata
!68, i32 33554949, metadata !12, i32 0, i32 0} ; [ DW_TAG_arg_variable ]
[this] [line 517]
!63 is DW_TAG_subprogram scope.
'this' should exist through this subprogram, and never disappear. But it
becomes "optimized away" after the last explicit use. Same is true with
any other variable.
Doesn't this mean that llvm generates wrong DWARF info?...

[LLVMdev] [RFC] Less memory and greater maintainability for debug info IR
In r219010, I merged integer and string fields into a single header
field. By reducing the number of metadata operands used in debug info,
this saved 2.2GB on an `llvm-lto` bootstrap. I've done some profiling
of DW_TAGs to see what parts of PR17891 and PR17892 to tackle next, and
I've concluded that they will be insufficient.
Instead, I'd like to implement a more aggressive plan,
