Running gdb in emacs.

[aprekates]

Hi.

I found those two basic ways to start gdb in emacs:

1.  M-x gdb

2.  M-x gud-gdb

In the first case i pass the  --interpreter=mi option to enable the 
gdb-mi and i can use various other windows like stackframes, registers , 
output etc.

In the second case i have only the source and a gdb window in user 
interface. If i give  --interpreter=mi after M-x gud-gdb i get only a 
gdb windows which seems to work in machine mode.

So i dont understand what is the proposed use case of using M-x gud-gdb 
since it seems it offers a basic debugging enviroment.

Also M-x gdb does it use GUD?
