Adding useful formatting options to the expression (expr) command. As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously These options do not apply to print, p or po because these are aliased to not take any options. In order to use them, use expression or expr. llvm-svn: 171993
This example has a function call in foo.c named "foo" that takes a forward declaration to "struct bar" and uses it as a pointer argument. In main.c we have a real declaration for "struct bar". We want to be able to find the real definition of "struct bar" when we are stopped in foo in foo.c such that when we stop in "foo" we see the contents of the "bar_ptr".
