Extended Description

I have an assembly file containing thumb2-it(thumb2 IF THEN) instructions which i need to check for single step in gdb. The problem being faced is that when i am compiling this assembly .S file using clang with -g option and running the generated executable on gdb, It says no debugging symbols found.

When I compiled the same assembly file using gcc(using the -g compile option), the executable created contained the debug information.

When I looked into the the executables generated using the readelf -a command, I found that the .debug_* info is absent from the clang compiled executable.

Attached the assembly file which is being used.

Obviously you think/knows its not a Windows specific , but the fact remains: its un-usable under Windows ;)

The bug

This bug actually makes clang unusable under Windows, is there a chance it will addressed? The bug is not connected with windows at all.
