GDB
supports a fairly large subset of Ada expression syntax, with some
extensions. The philosophy behind the design of this subset is
- That
GDB
should provide basic literals and access to operations for arithmetic, dereferencing, field selection, indexing, and subprogram calls, leaving more sophisticated computations to subprograms written into the program (which therefore may be called fromGDB
).- That type safety and strict adherence to Ada language restrictions are not particularly relevant in a debugging context.
- That brevity is important to the
GDB
user.
Thus, for brevity, the debugger acts as if there were
implicit with
and use
clauses in effect for all user-written
packages, thus making it unnecessary to fully qualify most names with
their packages, regardless of context. Where this causes ambiguity,
GDB
asks the user’s intent.
