[LLVMdev] DW_AT_location not getting generated for local variables
..., metadata !5, i32 1, i32 1, metadata !7, i32 0}
; [ DW_TAG_lexical_block ]
!16 = metadata !{i32 2, i32 2, metadata !14, null}
!17 = metadata !{i32 3, i32 3, metadata !14, null}
!18 = metadata !{i32 4, i32 4, metadata !14, null}

And this is what dwarfdump on the compiled object file shows. The
TAG_variable entry for 'bar' is missing its AT_location.

[LLVMdev] Local variable information in scope
Hi,
I want to list some additional information on this.
The variable collection I am looking at is, "variables 'declared' in scope".
1. When I traverse the MachineInstructions in the LexicalScopes ranges, and check for variables, I get variables used in this scope.
The variables listed include variables which may not have been declared in the scope. (for example

[LLVMdev] Compile units in debugging intrinsics / globals
...int is not defined), and fn2 appears to be in
compile unit "file3". My dwarf records are therefore incorrect, appearing
something like
TAG_compile_unit "file1"
TAG_subprogram "fn1" ...
...
TAG_base_type "int" ...
TAG_compile_init "file2"
TAG_variable "a" ...
TAG_compile_unit "file3"
TAG_subprogram "fn2" ...
...
When, in fact, these compile units "file2" and "file3" are bogus and
everything should be part of compile_unit "file1".
My question is: can I tell that these three (llv...

addition of vendor dwarf operator extension.
Hello,
Thanks for prompt reply.
Motivation,
In case of debugging of bi-endian dwarf and value known at runtime some of the raw values needs to be byte swapped to change the endianity. We have a llvm based compiler which generates such dwarf, TAG_variable marked as big endian and debugging on little endian host using lldb. The listed operator on dwarf issues does that, one operator instead of list of operators.
Proposal,
Addition of listed dwarf operator as vender extension in llvm/lldb till it gets released.
Regards,

addition of vendor dwarf operator extension.
Hello all,
There is one enhancement request open for dwarfv5, http://dwarfstd.org/ShowIssue.php?issue=191107.1
The request is for addition of dwarf expression operator to swap the top of the dwarf stack, the response seems positive but it may take some time till v6.
I like to add that operator as vendor extension but I am not sure how to go about it for llvm/lldb. Currently I am using it as
