GDB supports a fairly large subset of Ada expression syntax, with some
extensions. The philosophy behind the design of this subset is
GDBshould 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 from
Thus, for brevity, the debugger acts as if there were
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.
