Commit log for first patchset: ----- i#1569 AArch64: Implement parts of instr.c. Implement the functions that are called during execution of a simple program. Assembly Languages COMS W4995-02 Prof. Stephen A. Edwards Fall 2002 Columbia University Department of Computer Science Assembly Languages One step up from machine language Originally a more user-friendly way to program Now mostly a compiler target Model of computation: stored program computer Assembly Language Model PC ! add r1,r2 sub r2,r3 This reference is intended to be precise opcode and instruction set reference (including x86-64). Its principal aim is exact definition of instruction parameters and attributes. In this work we propose HMC Instruction Prediction Extensions (HIPE), that supports predicated execution inside the memory, in order to transform control-flow dependencies into data-flow dependencies. Our mechanism focus on removing the high latency iteration between the processor and the smart memory during the execution of branches that user does not need to know about the bundling of instructions on Itanium, the various addressing modes on each architecture, the different forms of predication supported by Itanium and ARM, x86 string instructions that can write a variable-size memory area, or x86 instructions like push that can implicitly write memory. A Beginners' Guide to x86-64 Instruction Encoding tagged asm, binary, encoding, gcc, Howto, Linux, Programming, Tutorial, x64, x86-64. Instructions not so marked are not critical. On the x86 processor, instructions are variable-sized, so disassembling backward is an exercise in pattern matching. To disassemble backward from an address, you should start disassembling at a point further back than you really want to go, then look forward until the instructions start making sense Predicated instructions with different predicates can be mixed with each other and with unconditional code, allowing better instruction scheduling and so even better performance. Elimination of unnecessary branch instructions can make the execution of necessary branches, such as those that make up loops, faster by lessening the load on branch MIPS??(??:MIPS architecture,?Microprocessor without interlocked piped stages architecture???,??Millions of Instructions Per Second????),??????????(RISC)??????,1981???,?MIPS?????????,?? We also use INS_InsertPredicatedCall instead of INS_InsertCall to avoid generating references to instructions that are predicated when the predicate is false see here. _ When the instruction has a predicate and the predicate is false, the analysis function is not called see here.
