JEB MIPS Decompiler - JEB Decompiler by PNF Software Not to mention other intricacies inherent to a RISC instruction set, such as unaligned reads and writes; or counter-intuitive idioms closely tight to the MIPS architecture itself, such as the branch delay slots or seemingly opaque code blocks. A strong decompiler is a precious tool to deep dive into MIPS code efficiently. Instruction Pipelining Review: - PowerPoint PPT Presentation branch-delay slot instruction. When the branch goes as predicted, the instruction in the branch delay slot is executed normally. When the branch does not go as predicted the instruction is turned into a no-op (i.e. cancelled). Canceling branches eliminate the conditions on instruction selection in delay instruction strategies B, C
delayed branch: Always execute instruction after branch. ... The original SPARC and MIPS processors used a branch delay slot to eliminate single-cycle stalls ...

Branch on Less than Zero, Branch on Greater than Zero
The delayed branch means that the instruction following the branch is always executed before the PC is modified to perform the branch.The MIPS R4000, part 9: Stupid branch delay slot tricks – The Old .. MIPS Delay Slot Instructions: TotalView Reference Guide (v6.3)Sequential successors are in the branch-delay slots. These instructions are .. MIPS instruction set | Wiki | Everipedia All MIPS I control flow instructions are followed by a branch delay slot. Unless the branch delay slot is filled by an instruction performing useful work, an nop is substituted. MIPS I branch instructions compare the contents of a GPR (rs) against zero or another GPR (rt) as signed integers and branch if the specified condition is true. Migrating from MIPS to ARM The most obvious difference is that MIPS branch instructions have a “branch shadow”, sometimes called a “branch delay slot”. This means that the instruction immediately following a branch instruction is always executed, whether or not the branch itself is taken. MIPS Goes Open Source | Hacker News > Branch delay slots are no big deal once you know they're there. I disagree. I'm not really a MIPS user, but I've managed to encounter some branch delay slot issues, and, as an x86 system programmer, I can only imagine how unpleasant they must be.
