I have found you in LLVM Developers page (http://llvm.org/developers.cgi).
First thank you for all of your work with LLVM.
I work with the LLVM Compiler Infrastructure to implement a backend for
specific processor xPEC of chip NetX (http://hilscher.com/netx.html).
So C-code already possible compile to the native xPEC assembly code (works
perfect! LLWM a big power!).
Now I need to debug the source C-code, that I compile for xPEC-processor. I
have read the article "Source Level Debugging with LLVM"
(http://llvm.org/docs/SourceLevelDebugging.html), where were described that
is possible to use debugger GDB. Wonderful! I have found much information
about GDB (of course http://sourceware.org/gdb/ ) and it has a debugging of
I don't understand how must be compiled the C-code with "llvm-gcc". Wenn I
use option "-emit-llvm" [backend needs it] of course with "-g" and "-O0",
then GDB can't find a symbol table in bc-file. Where will place "llvm-gcc"
the symbol table for DGB? Perhaps, must GDB knows the architecture of
processor? If yes, so where it must be written? I have many questions and
need some help.
Do you can help me what must I read and search ore recommend somebody to
