.LABEL Directive
.LABEL Directive
The .LABEL directive permits a label definition to appear within a
sequence of instructions that occur on a single line.
Syntax
.LABEL label_id
Parameters
label_id Names the label identifier.
NOTE The .LABEL directive is especially useful when using the M4 macro
processor or the C preprocessor (cpp). You would normally use this
directive in a DEFINE macro that includes multiple instructions.
Example
This example defines a cpp macro named Loop.
#define Loop(xx) LDO xx(%r0),%r1 ! .LABEL Loop ! ADDI,=-1,%r1,%r1 \
! BL Loop,%r0 ! NOP ! LDI 1,%ret0 ; macro
