simple test case with a const static
Calling "expr" or "target variable" on a constant static global in C doesn't
work. The error is
error: use of undeclared identifier 'limit'
or
error: can't find global variable 'limit'
It seems the variable is given the 'DW_AT_const_value' DWARF attribute. However
lldb can't find it. If you compile slightly differently so is has a
'DW_AT_location' attribute instead, lldb deals with it okay.
This works in gcc, which produces a 'DW_AT_location' attribute.
To reproduce compile with "clang -g -O0 InspectConstStatic.c"
Then call lldb with the commands:
b main
r
expr limit
