-LLVM IR (textual / bitcode representation) SUPPORT
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The below example is used to show the IR output generated by
-:program:`llvm-debuginfo-analyzer`. We compiled the example for a
-IR 64-bit target with Clang (-O0 -g --target=x86_64-linux):
+COMPARISON MODE
+^^^^^^^^^^^^^^^
+Given the previous example we found the above debug information issue
+(related to the previous invalid scope location for the **'typedef int
+INTEGER'**) by comparing against another compiler.
-.. code-block:: c++
+Using GCC to generate test-dwarf-gcc.o, we can apply a selection pattern
+with the printing mode to obtain the following logical view output.
- 1 using INTPTR = const int *;
- 2 int foo(INTPTR ParamPtr, unsigned ParamUnsigned, bool ParamBool) {
- 3 if (ParamBool) {
- 4 typedef int INTEGER;
- 5 const INTEGER CONSTANT = 7;
- 6 return CONSTANT;
- 7 }
- 8 return ParamUnsigned;
- 9 }
+.. code-block:: none
-PRINT BASIC DETAILS
-^^^^^^^^^^^^^^^^^^^
-The following command prints basic details for all the logical elements
-sorted by the debug information internal offset; it includes its lexical
-level and debug info format.
+ llvm-debuginfo-analyzer --attribute=level
+ --select-regex --select-nocase --select=INTe
+ --report=list
+ --print=symbols,types
+ test-clang.o test-dwarf-gcc.o
+
+ Logical View:
+ [000] {File} 'test-clang.o'
+
+ [001] {CompileUnit} 'test.cpp'
+ [003] 4 {TypeAlias} 'INTEGER' -> 'int'
+ [004] 5 {Variable} 'CONSTANT' -> 'const INTEGER'
+
+ Logical View:
+ [000] {File} 'test-dwarf-gcc.o'
+
+ [001] {CompileUnit} 'test.cpp'
+ [004] 4 {TypeAlias} 'INTEGER' -> 'int'
+ [004] 5 {Variable} 'CONSTANT' -> 'const INTEGER'
+
+The output shows that both objects contain the same elements. But the
+**'typedef INTEGER'** is located at different scope level. The GCC
+generated object, shows **'4'**, which is the correct value.
+
+There are 2 comparison methods: logical view and logical elements.
+
+LOGICAL VIEW
+""""""""""""
+It compares the logical view as a whole unit; for a match, each compared
+logical element must have the same parents and children.
+
+The output shows in view form the **missing (-), added (+)** elements,
+giving more context by swapping the reference and target object files.

+ -[003] 4 {TypeAlias} 'INTEGER' -> 'int'
+
+The output shows the merging view path (reference and target) with the
+missing and added elements.
+
+LOGICAL ELEMENTS
+""""""""""""""""
+It compares individual logical elements without considering if their
+parents are the same. For both comparison methods, the equal criteria
+includes the name, source code location, type, lexical scope level.
