Can gcc not to emit nop nor noreorder when it tries to fill the delay
slot with nop?
All the surrounding instructions scheduled by GCC are within
noreorder sections aren't they?
If so, the assembler has nothing to put into the delay
slot.
If not, you have a valid point, we should just remit the branch
by itself with no reorder/macro section attributes.
