8.6.2.3 Special Characters
; and # are the line comment characters. Sub-instructions may be executed in order, in reverse-order, or in parallel. Instructions listed in the standard one-per-line format will be executed sequentially. To specify the executing order, use the following symbols:
- ->
- Sequential with instruction on the left first.
- <-
- Sequential with instruction on the right first.
- ||
- Parallel
-
abs a1 -> abs r0
- Execute these sequentially. The instruction on the right is in the right container and is executed second.
-
abs r0 <- abs a1
- Execute these reverse-sequentially. The instruction on the right is in the right container, and is executed first.
-
ld2w r2,@r8+ || mac a0,r0,r7
- Execute these in parallel.
-
ld2w r2,@r8+ ||
-
mac a0,r0,r7
- Two-line format. Execute these in parallel.
-
ld2w r2,@r8+
-
mac a0,r0,r7
- Two-line format. Execute these sequentially. Assembler will put them in the proper containers.
-
ld2w r2,@r8+ ->
-
mac a0,r0,r7
- Two-line format. Execute these sequentially. Same as above but second instruction will always go into right container.
