<pre>Given the following test case:
//------------------------------------------------------------
// inlined.cpp
//------------------------------------------------------------
int inlineFunction(int Param) __attribute__((always_inline));
int inlineFunction(int Param) {
int Var_1 = Param;
{
int Var_2 = Param + Var_1;
Var_1 = Var_2;
}
return Var_1;
}
int testInlined(int Param_1, int Param_2) {
int A = Param_1;
A += inlineFunction(Param_2);
return A;
}
//------------------------------------------------------------
Using the following command line options to generate debug info
(DWARF) and (COFF):
clang -c -g -O0 inlined.cpp -o inlined-dwarf.o
clang -c -g -O0 inlined.cpp -o inlined-coff.o -gcodeview
--target=x86_64-windows
Looking at the output generated by llvm-dwarfdump and llvm-readobj,
the COFF debug info shows the variable 'Var_2' at the same lexical
scope as the variable 'Var_1' in the 'testInlined' as results of the
function 'inlineFunction' being inlined.
llvm-dwarfdump --debug-info inlined-dwarf.o</pre>
