13.2.10 Enumerations

Enumeration members are converted to .enum elements in assembly. For example:

enum state { ACTIVE=0x10, SLEEPING=0x01, INTERRUPT=0x100, POWEROFF, LAST};

is converted to the following assembly code:

state .enum ACTIVE .emember 16 SLEEPING .emember 1 NTERRUPT .emember 256 POWEROFF .emember 257 LAST .emember 258 .endenum

The members are used via the pseudo-scoping created by the .enum directive.

The usage is similar to that for accessing structure members, enum_name.member.

This pseudo-scoping is used to prevent enumeration member names from corrupting other symbols within the assembly environment.
