/* How GDB's character set support works
|
||
|
||
GDB has two global settings:
|
||
|
||
- The `current host character set' is the character set GDB should
|
||
use in talking to the user, and which (hopefully) the user's
|
||
terminal knows how to display properly.
|
||
|
||
- The `current target character set' is the character set the
|
||
program being debugged uses.
|
||
|
||
There are commands to set each of these, and mechanisms for
|
||
choosing reasonable default values. GDB has a global list of
|
||
character sets that it can use as its host or target character
|
||
sets.
|
||
|
||
The header file `charset.h' declares various functions that
|
||
different pieces of GDB need to perform tasks like:
|
||
|
||
- printing target strings and characters to the user's terminal
|
||
(mostly target->host conversions),
|
||
|
||
- building target-appropriate representations of strings and
|
||
characters the user enters in expressions (mostly host->target
|
||
conversions),
|
||
|
||
and so on.
|
||
|
||
Now, many of these operations are specific to a particular
|
||
host/target character set pair. If GDB supports N character sets,
|
||
there are N^2 possible pairs. This means that, the larger GDB's
|
||
repertoire of character sets gets, the more expensive it gets to add
|
||
new character sets.
|
||
|
||
To make sure that GDB can do the right thing for every possible
|
||
pairing of host and target character set, while still allowing
|
||
GDB's repertoire to scale, we use a two-tiered approach:
|
||
|
||
- We maintain a global table of "translations" --- groups of
|
||
functions specific to a particular pair of character sets.
|
||
|
||
- However, a translation can be incomplete: some functions can be
|
||
omitted. Where there is not a translation to specify exactly
|
||
what function to use, we provide reasonable defaults. The
|
||
default behaviors try to use the "iconv" library functions, which
|
||
support a wide range of character sets. However, even if iconv
|
||
is not available, there are fallbacks to support trivial
|
||
translations: when the host and target character sets are the
|
||
same. */
