Some Merits of GDB

There are some impressive features of GDB which I would like to point out :

1. GDB targets a good range of processors which includes Alpha, ARM, AVR, H8/300, System/370, System 390, X86 and its 64-bit extension X86-64, IA-64 "Itanium", Motorola 68000, MIPS, PA-RISC, PowerPC, SuperH, SPARC, and VAX.

2.GDB offers a remote mode.gdbserver can be used to remotely debug the program

3.The file caching mechanism is embedded within BFD and allows the application to open as many BFDs as it wants without regard to the underlying operating system's file descriptor limit.

Some features which I would like to have :

Display of variable values in a tree structure by a single command.
