15.4.9.9 GDB and Modula-2
Some GDB commands have little use when debugging Modula-2 programs.
Five subcommands of set print
and show print
apply
specifically to C and C++
: ‘vtbl
’, ‘demangle
’,
‘asm-demangle
’, ‘object
’, and ‘union
’. The first four
apply to C++
, and the last to the C union
type, which has no direct
analogue in Modula-2.
The @
operator (see Expressions), while available
with any language, is not useful with Modula-2. Its
intent is to aid the debugging of dynamic arrays, which cannot be
created in Modula-2 as they can in C or C++
. However, because an
address can be specified by an integral constant, the construct
‘{type}adrexp
’ is still useful.
In GDB scripts, the Modula-2 inequality operator #
is
interpreted as the beginning of a comment. Use <>
instead.
