Copy the characters in @var{str} to the object file. You may specify more than
|
||||
one string to copy, separated by commas. Unless otherwise specified for a
|
||||
particular machine, the assembler marks the end of each string with a 0 byte.
|
||||
You can use any of the escape sequences described in @ref{Strings,,Strings}.
|
||||
|
||||
The variants @code{string16}, @code{string32} and @code{string64} differ from
|
||||
the @code{string} pseudo opcode in that each 8-bit character from @var{str} is
|
||||
copied and expanded to 16, 32 or 64 bits respectively. The expanded characters
|
||||
are stored in target endianness byte order.
|
||||
|
||||
Example:
|
||||
@smallexample
|
||||
.string32 "BYE"
|
||||
expands to:
|
||||
.string "B\0\0\0Y\0\0\0E\0\0\0" /* On little endian targets. */
|
||||
.string "\0\0\0B\0\0\0Y\0\0\0E" /* On big endian targets. */
