|
|||
When you want to make @value{GDBN} work ``native'' on a particular machine, you
|
||||
have to include all three kinds of information.
|
||||
|
||||
@section Source Tree Structure
|
||||
@cindex @value{GDBN} source tree structure
|
||||
|
||||
The @value{GDBN} source directory has a mostly flat structure---there
|
||||
are only a few subdirectories. A file's name usually gives a hint as
|
||||
to what it does; for example, @file{stabsread.c} reads stabs,
|
||||
@file{dwarfread.c} reads DWARF, etc.
|
||||
|
||||
Files that are related to some common task have names that share
|
||||
common substrings. For example, @file{*-thread.c} files deal with
|
||||
debugging threads on various platforms; @file{*read.c} files deal with
|
||||
reading various kinds of symbol and object files; @file{inf*.c} files
|
||||
deal with direct control of the @dfn{inferior program} (@value{GDBN}
|
||||
parlance for the program being debugged).
|
||||
|
||||
There are several dozens of files in the @file{*-tdep.c} family.
|
||||
@samp{tdep} stands for @dfn{target-dependent code}---each of these
|
||||
files implements debug support for a specific target architecture
|
||||
(sparc, mips, etc). Usually, only one of these will be used in a
|
||||
specific @value{GDBN} configuration (sometimes two, closely related).
|
||||
|
||||
Similarly, there are many @file{*-nat.c} files, each one for native
|
||||
debugging on a specific system (e.g., @file{sparc-linux-nat.c} is for
|
||||
native debugging of Sparc machines running the Linux kernel).
|
||||
|
||||
The few subdirectories of the source tree are:
|
||||
|
||||
@table @file
|
||||
@item cli
|
||||
Code that implements @dfn{CLI}, the @value{GDBN} Command-Line
|
||||
Interpreter. @xref{User Interface, Command Interpreter}.
|
||||
|
||||
@item gdbserver
|
||||
Code for the @value{GDBN} remote server.
|
||||
|
||||
@item gdbtk
|
||||
Code for Insight, the @value{GDBN} TK-based GUI front-end.
|
||||
|
||||
@item mi
|
||||
The @dfn{GDB/MI}, the @value{GDBN} Machine Interface interpreter.
|
||||
|
||||
@item signals
|
||||
Target signal translation code.
|
||||
|
||||
@item tui
|
||||
Code for @dfn{TUI}, the @value{GDBN} Text-mode full-screen User
|
||||
Interface. @xref{User Interface, TUI}.
