*** Changes since GDB 5.2: *** Changes since GDB 5.2:
* GDB now supports C/C++ preprocessor macros.
GDB now expands preprocessor macro invocations in C/C++ expressions,
and provides various commands for showing macro definitions and how
they expand.
Most compilers don't include information about macros in the debugging
information by default. In GCC 3.1, for example, you need to compile
your program with the options `-gdwarf-2 -g3'. If the macro
information is present in the executable, GDB will read it.
Here are the new commands for working with macros:
** macro expand EXPRESSION
Expand any macro invocations in expression, and show the result.
** show macro MACRO-NAME
Show the definition of the macro named MACRO-NAME, and where it was
defined.
