Summary: MIPSR6 introduces a class of branches called compact branches. Unlike the traditional MIPS branches which have a delay slot, compact branches do not have a delay slot. The instruction following the compact branch is only executed if the branch is not taken and must not be a branch. It works by generating compact branches for MIPS32R6 when the delay slot filler cannot fill a delay slot. Then, inspecting the generated code for forbidden slot hazards (a compact branch with an adjacent branch or other CTI) and inserting nops to clear this hazard. Patch by Simon Dardis.
