A semicolon (‘;’) can be used anywhere on a line to start a comment that extends to the end of the line.
If a ‘#’ appears as the first character of a line, the whole line is treated as a comment, but in this case the line could also be a logical line number directive (see Comments) or a preprocessor control command (see Preprocessing).
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.
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+ ||
Two-line format. Execute these in parallel.
Two-line format. Execute these sequentially. Assembler will put them in the proper containers.
ld2w r2,@r8+ ->
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.
