The .ORIGIN
directive advances the location counter to the specified location. Syntax | |
Parameters | |
- location
The integer value used to advance the location counter
to that absolute location. The location counter value may not decrease
during this process; that is, the value specified cannot be less
than the value of the current location counter. The default value is zero.
Discussion | |
When the Assembler encounters an .ORIGIN
directive, it issues a .BLOCK
pseudo-operation of a size calculated to advance the location counter
to the requested origin. See “.BLOCK and .BLOCKZ Pseudo-Operations” in this chapter. Example | |
This sample program performs an exclusive OR,
advances the location counter to 64 bytes, and branches to the label
idx. .CODE
XOR %r21,%r22,%r23
B idx
NOP
.ORIGIN 64
idx LDWX %r23(%sr0,%sr0),%r3
.END |
