Compiler-specific Features
replaced by a reference to the real variable. Where a variable is defined as static, the
variable name is replaced by the alias name and the variable is declared external if the
alias is declared external.
Note
Function names might also be aliased using the corresponding function attribute
__attribute__((alias)).
Syntax
type newname __attribute__((alias("oldname")));
Where:
oldname
newname
is the name of the variable to be aliased
is the new name of the aliased variable.
Example
#include
int oldname = 1;
extern int newname __attribute__((alias("oldname"))); // declaration
void foo(void)
{
printf("newname = %d\n", newname); // prints 1
}

4.5.2 __attribute__((at(address)))
This variable attribute enables you to specify the absolute address of a variable.
The variable is placed in its own section, and the section containing the variable is given
an appropriate type by the compiler:
• Read-only variables are placed in a section with type RO.
• Initialized read-write variables are placed in a section with type RW.
