Hi Devang,
I convert all global variables in a file to thread local at the IR level.
i.e. compile example_llvm.c to IR example_llvm.ll and change global
variables to thread-local variables. I also insert a function call just before
access of the global(now thread-local) variable. I also insert a local variable
in main. Does these operations in any way effect the debug metadata ?
I do not face any issues debugging my test case. But while debugging
my application
through gdb I cannot make sense of the call stack. I do not see the
function names in
the call stack (with or without insertion of additional function calls
or local variables).
