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
The D10V syntax allows either one instruction per line, one instruction per line with the execution symbol, or two instructions per line. For example
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.
Since `$' has no special meaning, you may use it in symbol names.
