pragma Linker_Alias ( [Entity =>] LOCAL_NAME, [Target =>] static_string_EXPRESSION);
LOCAL_NAME must refer to an object that is declared at the library
level. This pragma establishes the given entity as a linker alias for the
given target. It is equivalent to
__attribute__((alias)) in GNU C
and causes LOCAL_NAME to be emitted as an alias for the symbol
static_string_EXPRESSION in the object file, that is to say no space
is reserved for LOCAL_NAME by the assembler and it will be resolved
to the same address as static_string_EXPRESSION by the linker.
The actual linker name for the target must be used (e.g. the fully
encoded name with qualification in Ada, or the mangled name in C++),
or it must be declared using the C convention with
Not all target machines support this pragma. On some of them it is accepted
pragma Weak_External has been applied to LOCAL_NAME.
-- Example of the use of pragma Linker_Alias package p is i : Integer := 1; pragma Export (C, i); new_name_for_i : Integer; pragma Linker_Alias (new_name_for_i, "i"); end p;
