X86/X64 compiler implementation. //! //! ### Compiler Basics //! //! The first \ref x86::Compiler example shows how to generate a function that simply returns an integer value. It's //! an analogy to the first Assembler example: //! //! ``` //! #include //! #include //! //! using namespace asmjit; //! //! // Signature of the generated function. //! typedef int (*Func)(void); //! //! int main() { //! JitRuntime rt; // Runtime specialized for JIT code execution. //! CodeHolder code; // Holds code and relocation information. //! //! code.init(rt.environment(), // Initialize code to match the JIT environment. //! rt.cpuFeatures()); //! x86::Compiler cc(&code); // Create and attach x86::Compiler to code. //! //! cc.addFunc(FuncSignatureT());// Begin a function of `int fn(void)` signature. //! //! x86::Gp vReg = cc.newGpd(); // Create a 32-bit general purpose register. //! cc.mov(vReg, 1); // Move one to our virtual register `vReg`. //! cc.ret(vReg); // Return `vReg` from the function. //! //! cc.endFunc(); // End of the function body. //! cc.finalize(); // Translate and assemble the whole 'cc' content. //! // ----> x86::Compiler is no longer needed from here and can be destroyed <---- //! //! Func fn; //! Error err = rt.add(&fn, &code); // Add the generated code to the runtime. //! if (err) return 1; // Handle a possible error returned by AsmJit. //! // ----> CodeHolder is no longer needed from here and can be destroyed <---- //! //! int result = fn(); // Execute the generated code. //! printf("%d\n", result); // Print the resulting "1". //! //! rt.release(fn); // Explicitly remove the function from the runtime. //! return 0; //! } //! ``` //! //! The \ref BaseCompiler::addFunc() and \ref BaseCompiler::endFunc() functions are used to define the function and //! its end. Both must be called per function, but the body doesn't have to be generated in sequence. An example of //! generating two functions will be shown later. The next example shows more complicated code that contain a loop //! and generates a simple memory copy function that uses `uint32_t` items: //! //! ``` //! #include //! #include //! //! using namespace asmjit; //! //! // Signature of the generated function. //! typedef void (*MemCpy32)(uint32_t* dst, const uint32_t* src, size_t count); //! //! int main() { //! JitRuntime rt; // Runtime specialized for JIT code execution. //! CodeHolder code; // Holds code and relocation information. //! //! code.init(rt.environment(), // Initialize code to match the JIT environment. //! rt.cpuFeatures()); //! x86::Compiler cc(&code); // Create and attach x86::Compiler to code. //! //! FuncNode* funcNode = cc.addFunc( // Begin the function of the following signature: //! FuncSignatureT()); // 3rd argument - size_t (machine reg-size). //! //! Label L_Loop = cc.newLabel(); // Start of the loop. //! Label L_Exit = cc.newLabel(); // Used to exit early. //! //! x86::Gp dst = cc.newIntPtr("dst");// Create `dst` register (destination pointer). //! x86::Gp src = cc.newIntPtr("src");// Create `src` register (source pointer). //! x86::Gp i = cc.newUIntPtr("i"); // Create `i` register (loop counter). //! //! funcNode->setArg(0, dst); // Assign `dst` argument. //! funcNode->setArg(1, src); // Assign `src` argument. //! funcNode->setArg(2, i); // Assign `i` argument. //! //! cc.test(i, i); // Early exit if length is zero. //! cc.jz(L_Exit); //! //! cc.bind(L_Loop); // Bind the beginning of the loop here. //! //! x86::Gp tmp = cc.newInt32("tmp"); // Copy a single dword (4 bytes). //! cc.mov(tmp, x86::dword_ptr(src)); // Load DWORD from [src] address. //! cc.mov(x86::dword_ptr(dst), tmp); // Store DWORD to [dst] address. //! //! cc.add(src, 4); // Increment `src`. //! cc.add(dst, 4); // Increment `dst`. //! //! cc.dec(i); // Loop until `i` is non-zero. //! cc.jnz(L_Loop); //! //! cc.bind(L_Exit); // Label used by early exit. //! cc.endFunc(); // End of the function body. //! //! cc.finalize(); // Translate and assemble the whole 'cc' content. //! // ----> x86::Compiler is no longer needed from here and can be destroyed <---- //! //! // Add the generated code to the runtime. //! MemCpy32 memcpy32; //! Error err = rt.add(&memcpy32, &code); //! //! // Handle a possible error returned by AsmJit. //! if (err) //! return 1; //! // ----> CodeHolder is no longer needed from here and can be destroyed <---- //! //! // Test the generated code. //! uint32_t input[6] = { 1, 2, 3, 5, 8, 13 }; //! uint32_t output[6]; //! memcpy32(output, input, 6); //! //! for (uint32_t i = 0; i < 6; i++) //! printf("%d\n", output[i]); //! //! rt.release(memcpy32); //! return 0; //! } //! ``` //! //! ### AVX and AVX-512 //! //! AVX and AVX-512 code generation must be explicitly enabled via \ref FuncFrame to work properly. If it's not setup //! correctly then Prolog & Epilog would use SSE instead of AVX instructions to work with SIMD registers. In addition, //! Compiler requires explicitly enable AVX-512 via \ref FuncFrame in order to use all 32 SIMD registers. //! //! ``` //! #include //! #include //! //! using namespace asmjit; //! //! // Signature of the generated function. //! typedef void (*Func)(void*); //! //! int main() { //! JitRuntime rt; // Runtime specialized for JIT code execution. //! CodeHolder code; // Holds code and relocation information. //! //! code.init(rt.environment(), // Initialize code to match the JIT environment. //! rt.cpuFeatures()); //! x86::Compiler cc(&code); // Create and attach x86::Compiler to code. //! //! FuncNode* funcNode = cc.addFunc(FuncSignatureT()); //! //! // Use the following to enable AVX and/or AVX-512. //! funcNode->frame().setAvxEnabled(); //! funcNode->frame().setAvx512Enabled(); //! //! // Do something with the input pointer. //! x86::Gp addr = cc.newIntPtr("addr"); //! x86::Zmm vreg = cc.newZmm("vreg"); //! //! funcNode->setArg(0, addr); //! //! cc.vmovdqu32(vreg, x86::ptr(addr)); //! cc.vpaddq(vreg, vreg, vreg); //! cc.vmovdqu32(x86::ptr(addr), vreg); //! //! cc.endFunc(); // End of the function body. //! cc.finalize(); // Translate and assemble the whole 'cc' content. //! // ----> x86::Compiler is no longer needed from here and can be destroyed <---- //! //! Func fn; //! Error err = rt.add(&fn, &code); // Add the generated code to the runtime. //! if (err) return 1; // Handle a possible error returned by AsmJit. //! // ----> CodeHolder is no longer needed from here and can be destroyed <---- //! //! // Execute the generated code and print some output. //! uint64_t data[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; //! fn(data); //! printf("%llu\n", (unsigned long long)data[0]); //! //! rt.release(fn); // Explicitly remove the function from the runtime. //! return 0; //! } //! ``` //! //! ### Recursive Functions //! //! It's possible to create more functions by using the same \ref x86::Compiler instance and make links between them. //! In such case it's important to keep the pointer to \ref FuncNode. //! //! The example below creates a simple Fibonacci function that calls itself recursively: //! //! ``` //! #include //! #include //! //! using namespace asmjit; //! //! // Signature of the generated function. //! typedef uint32_t (*Fibonacci)(uint32_t x); //! //! int main() { //! JitRuntime rt; // Runtime specialized for JIT code execution. //! CodeHolder code; // Holds code and relocation information. //! //! code.init(rt.environment(), // Initialize code to match the JIT environment. //! rt.cpuFeatures()); //! x86::Compiler cc(&code); // Create and attach x86::Compiler to code. //! //! FuncNode* funcNode = cc.addFunc( // Begin of the Fibonacci function, addFunc() //! FuncSignatureT()); // Returns a pointer to the FuncNode node. //! //! Label L_Exit = cc.newLabel() // Exit label. //! x86::Gp x = cc.newUInt32(); // Function x argument. //! x86::Gp y = cc.newUInt32(); // Temporary. //! //! funcNode->setArg(0, x); //! //! cc.cmp(x, 3); // Return x if less than 3. //! cc.jb(L_Exit); //! //! cc.mov(y, x); // Make copy of the original x. //! cc.dec(x); // Decrease x. //! //! InvokeNode* invokeNode; // Function invocation: //! cc.invoke(&invokeNode, // - InvokeNode (output). //! funcNode->label(), // - Function address or Label. //! FuncSignatureT()); // - Function signature. //! //! invokeNode->setArg(0, x); // Assign x as the first argument. //! invokeNode->setRet(0, x); // Assign x as a return value as well. //! //! cc.add(x, y); // Combine the return value with y. //! //! cc.bind(L_Exit); //! cc.ret(x); // Return x. //! cc.endFunc(); // End of the function body. //! //! cc.finalize(); // Translate and assemble the whole 'cc' content. //! // ----> x86::Compiler is no longer needed from here and can be destroyed <---- //! //! Fibonacci fib; //! Error err = rt.add(&fib, &code); // Add the generated code to the runtime. //! if (err) return 1; // Handle a possible error returned by AsmJit. //! // ----> CodeHolder is no longer needed from here and can be destroyed <---- //! //! // Test the generated code. //! printf("Fib(%u) -> %u\n", 8, fib(8)); //! //! rt.release(fib); //! return 0; //! } //! ``` //! //! ### Stack Management //! //! Function's stack-frame is managed automatically, which is used by the register allocator to spill virtual //! registers. It also provides an interface to allocate user-defined block of the stack, which can be used as //! a temporary storage by the generated function. In the following example a stack of 256 bytes size is allocated, //! filled by bytes starting from 0 to 255 and then iterated again to sum all the values. //! //! ``` //! #include //! #include //! //! using namespace asmjit; //! //! // Signature of the generated function. //! typedef int (*Func)(void); //! //! int main() { //! JitRuntime rt; // Runtime specialized for JIT code execution. //! CodeHolder code; // Holds code and relocation information. //! //! code.init(rt.environment(), // Initialize code to match the JIT environment. //! rt.cpuFeatures()); //! x86::Compiler cc(&code); // Create and attach x86::Compiler to code. //! //! cc.addFunc(FuncSignatureT());// Create a function that returns int. //! //! x86::Gp p = cc.newIntPtr("p"); //! x86::Gp i = cc.newIntPtr("i"); //! //! // Allocate 256 bytes on the stack aligned to 4 bytes. //! x86::Mem stack = cc.newStack(256, 4); //! //! x86::Mem stackIdx(stack); // Copy of stack with i added. //! stackIdx.setIndex(i); // stackIdx <- stack[i]. //! stackIdx.setSize(1); // stackIdx <- byte ptr stack[i]. //! //! // Load a stack address to `p`. This step is purely optional and shows //! // that `lea` is useful to load a memory operands address (even absolute) //! // to a general purpose register. //! cc.lea(p, stack); //! //! // Clear i (xor is a C++ keyword, hence 'xor_' is used instead). //! cc.xor_(i, i); //! //! Label L1 = cc.newLabel(); //! Label L2 = cc.newLabel(); //! //! cc.bind(L1); // First loop, fill the stack. //! cc.mov(stackIdx, i.r8()); // stack[i] = uint8_t(i). //! //! cc.inc(i); // i++; //! cc.cmp(i, 256); // if (i < 256) //! cc.jb(L1); // goto L1; //! //! // Second loop, sum all bytes stored in `stack`. //! x86::Gp sum = cc.newInt32("sum"); //! x86::Gp val = cc.newInt32("val"); //! //! cc.xor_(i, i); //! cc.xor_(sum, sum); //! //! cc.bind(L2); //! //! cc.movzx(val, stackIdx); // val = uint32_t(stack[i]); //! cc.add(sum, val); // sum += val; //! //! cc.inc(i); // i++; //! cc.cmp(i, 256); // if (i < 256) //! cc.jb(L2); // goto L2; //! //! cc.ret(sum); // Return the `sum` of all values. //! cc.endFunc(); // End of the function body. //! //! cc.finalize(); // Translate and assemble the whole 'cc' content. //! // ----> x86::Compiler is no longer needed from here and can be destroyed <---- //! //! Func func; //! Error err = rt.add(&func, &code); // Add the generated code to the runtime. //! if (err) return 1; // Handle a possible error returned by AsmJit. //! // ----> CodeHolder is no longer needed from here and can be destroyed <---- //! //! printf("Func() -> %d\n", func()); // Test the generated code. //! //! rt.release(func); //! return 0; //! } //! ``` //! //! ### Constant Pool //! //! Compiler provides two constant pools for a general purpose code generation: //! //! - Local constant pool - Part of \ref FuncNode, can be only used by a single function and added after the //! function epilog sequence (after `ret` instruction). //! //! - Global constant pool - Part of \ref BaseCompiler, flushed at the end of the generated code by \ref //! BaseEmitter::finalize(). //! //! The example below illustrates how a built-in constant pool can be used: //! //! ``` //! #include //! //! using namespace asmjit; //! //! static void exampleUseOfConstPool(x86::Compiler& cc) { //! cc.addFunc(FuncSignatureT()); //! //! x86::Gp v0 = cc.newGpd("v0"); //! x86::Gp v1 = cc.newGpd("v1"); //! //! x86::Mem c0 = cc.newInt32Const(ConstPoolScope::kLocal, 200); //! x86::Mem c1 = cc.newInt32Const(ConstPoolScope::kLocal, 33); //! //! cc.mov(v0, c0); //! cc.mov(v1, c1); //! cc.add(v0, v1); //! //! cc.ret(v0); //! cc.endFunc(); //! } //! ``` //! //! ### Jump Tables //! //! x86::Compiler supports `jmp` instruction with reg/mem operand, which is a commonly used pattern to implement //! indirect jumps within a function, for example to implement `switch()` statement in a programming languages. //! By default AsmJit assumes that every basic block can be a possible jump target as it's unable to deduce targets //! from instruction's operands. This is a very pessimistic default that should be avoided if possible as it's costly //! and very unfriendly to liveness analysis and register allocation. //! //! Instead of relying on such pessimistic default behavior, let's use \ref JumpAnnotation to annotate a jump where //! all targets are known: //! //! ``` //! #include //! //! using namespace asmjit; //! //! static void exampleUseOfIndirectJump(x86::Compiler& cc) { //! FuncNode* funcNode = cc.addFunc(FuncSignatureT(CallConvId::kHost)); //! //! // Function arguments //! x86::Xmm a = cc.newXmmSs("a"); //! x86::Xmm b = cc.newXmmSs("b"); //! x86::Gp op = cc.newUInt32("op"); //! //! x86::Gp target = cc.newIntPtr("target"); //! x86::Gp offset = cc.newIntPtr("offset"); //! //! Label L_Table = cc.newLabel(); //! Label L_Add = cc.newLabel(); //! Label L_Sub = cc.newLabel(); //! Label L_Mul = cc.newLabel(); //! Label L_Div = cc.newLabel(); //! Label L_End = cc.newLabel(); //! //! funcNode->setArg(0, a); //! funcNode->setArg(1, b); //! funcNode->setArg(2, op); //! //! // Jump annotation is a building block that allows to annotate all possible targets where `jmp()` can //! // jump. It then drives the CFG construction and liveness analysis, which impacts register allocation. //! JumpAnnotation* annotation = cc.newJumpAnnotation(); //! annotation->addLabel(L_Add); //! annotation->addLabel(L_Sub); //! annotation->addLabel(L_Mul); //! annotation->addLabel(L_Div); //! //! // Most likely not the common indirect jump approach, but it //! // doesn't really matter how final address is calculated. The //! // most important path using JumpAnnotation with `jmp()`. //! cc.lea(offset, x86::ptr(L_Table)); //! if (cc.is64Bit()) //! cc.movsxd(target, x86::dword_ptr(offset, op.cloneAs(offset), 2)); //! else //! cc.mov(target, x86::dword_ptr(offset, op.cloneAs(offset), 2)); //! cc.add(target, offset); //! cc.jmp(target, annotation); //! //! // Acts like a switch() statement in C. //! cc.bind(L_Add); //! cc.addss(a, b); //! cc.jmp(L_End); //! //! cc.bind(L_Sub); //! cc.subss(a, b); //! cc.jmp(L_End); //! //! cc.bind(L_Mul); //! cc.mulss(a, b); //! cc.jmp(L_End); //! //! cc.bind(L_Div); //! cc.divss(a, b); //! //! cc.bind(L_End); //! cc.ret(a); //! //! cc.endFunc(); //! //! // Relative int32_t offsets of `L_XXX - L_Table`. //! cc.bind(L_Table); //! cc.embedLabelDelta(L_Add, L_Table, 4); //! cc.embedLabelDelta(L_Sub, L_Table, 4); //! cc.embedLabelDelta(L_Mul, L_Table, 4); //! cc.embedLabelDelta(L_Div, L_Table, 4); //! } //! ``` class ASMJIT_VIRTAPI Compiler : public BaseCompiler, public EmitterExplicitT { public: ASMJIT_NONCOPYABLE(Compiler) typedef BaseCompiler Base; //! \name Construction & Destruction //! \{ ASMJIT_API explicit Compiler(CodeHolder* code = nullptr) noexcept; ASMJIT_API virtual ~Compiler() noexcept; //! \} //! \name Virtual Registers //! \{ #ifndef ASMJIT_NO_LOGGING # define ASMJIT_NEW_REG_FMT(OUT, PARAM, FORMAT, ARGS) \ _newRegFmt(&OUT, PARAM, FORMAT, ARGS) #else # define ASMJIT_NEW_REG_FMT(OUT, PARAM, FORMAT, ARGS) \ DebugUtils::unused(FORMAT); \ DebugUtils::unused(std::forward(args)...); \ _newReg(&OUT, PARAM) #endif #define ASMJIT_NEW_REG_CUSTOM(FUNC, REG) \ inline REG FUNC(TypeId typeId) { \ REG reg(Globals::NoInit); \ _newReg(®, typeId); \ return reg; \ } \ \ template \ inline REG FUNC(TypeId typeId, const char* fmt, Args&&... args) { \ REG reg(Globals::NoInit); \ ASMJIT_NEW_REG_FMT(reg, typeId, fmt, std::forward(args)...); \ return reg; \ } #define ASMJIT_NEW_REG_TYPED(FUNC, REG, TYPE_ID) \ inline REG FUNC() { \ REG reg(Globals::NoInit); \ _newReg(®, TYPE_ID); \ return reg; \ } \ \ template \ inline REG FUNC(const char* fmt, Args&&... args) { \ REG reg(Globals::NoInit); \ ASMJIT_NEW_REG_FMT(reg, TYPE_ID, fmt, std::forward(args)...); \ return reg; \ } template inline RegT newSimilarReg(const RegT& ref) { RegT reg(Globals::NoInit); _newReg(reg, ref); return reg; } template inline RegT newSimilarReg(const RegT& ref, const char* fmt, Args&&... args) { RegT reg(Globals::NoInit); ASMJIT_NEW_REG_FMT(reg, ref, fmt, std::forward(args)...); return reg; } ASMJIT_NEW_REG_CUSTOM(newReg , Reg ) ASMJIT_NEW_REG_CUSTOM(newGp , Gp ) ASMJIT_NEW_REG_CUSTOM(newVec , Vec ) ASMJIT_NEW_REG_CUSTOM(newK , KReg) ASMJIT_NEW_REG_TYPED(newInt8 , Gp , TypeId::kInt8) ASMJIT_NEW_REG_TYPED(newUInt8 , Gp , TypeId::kUInt8) ASMJIT_NEW_REG_TYPED(newInt16 , Gp , TypeId::kInt16) ASMJIT_NEW_REG_TYPED(newUInt16 , Gp , TypeId::kUInt16) ASMJIT_NEW_REG_TYPED(newInt32 , Gp , TypeId::kInt32) ASMJIT_NEW_REG_TYPED(newUInt32 , Gp , TypeId::kUInt32) ASMJIT_NEW_REG_TYPED(newInt64 , Gp , TypeId::kInt64) ASMJIT_NEW_REG_TYPED(newUInt64 , Gp , TypeId::kUInt64) ASMJIT_NEW_REG_TYPED(newIntPtr , Gp , TypeId::kIntPtr) ASMJIT_NEW_REG_TYPED(newUIntPtr, Gp , TypeId::kUIntPtr) ASMJIT_NEW_REG_TYPED(newGpb , Gp , TypeId::kUInt8) ASMJIT_NEW_REG_TYPED(newGpw , Gp , TypeId::kUInt16) ASMJIT_NEW_REG_TYPED(newGpd , Gp , TypeId::kUInt32) ASMJIT_NEW_REG_TYPED(newGpq , Gp , TypeId::kUInt64) ASMJIT_NEW_REG_TYPED(newGpz , Gp , TypeId::kUIntPtr) ASMJIT_NEW_REG_TYPED(newXmm , Xmm , TypeId::kInt32x4) ASMJIT_NEW_REG_TYPED(newXmmSs , Xmm , TypeId::kFloat32x1) ASMJIT_NEW_REG_TYPED(newXmmSd , Xmm , TypeId::kFloat64x1) ASMJIT_NEW_REG_TYPED(newXmmPs , Xmm , TypeId::kFloat32x4) ASMJIT_NEW_REG_TYPED(newXmmPd , Xmm , TypeId::kFloat64x2) ASMJIT_NEW_REG_TYPED(newYmm , Ymm , TypeId::kInt32x8) ASMJIT_NEW_REG_TYPED(newYmmPs , Ymm , TypeId::kFloat32x8) ASMJIT_NEW_REG_TYPED(newYmmPd , Ymm , TypeId::kFloat64x4) ASMJIT_NEW_REG_TYPED(newZmm , Zmm , TypeId::kInt32x16) ASMJIT_NEW_REG_TYPED(newZmmPs , Zmm , TypeId::kFloat32x16) ASMJIT_NEW_REG_TYPED(newZmmPd , Zmm , TypeId::kFloat64x8) ASMJIT_NEW_REG_TYPED(newMm , Mm , TypeId::kMmx64) ASMJIT_NEW_REG_TYPED(newKb , KReg, TypeId::kMask8) ASMJIT_NEW_REG_TYPED(newKw , KReg, TypeId::kMask16) ASMJIT_NEW_REG_TYPED(newKd , KReg, TypeId::kMask32) ASMJIT_NEW_REG_TYPED(newKq , KReg, TypeId::kMask64) #undef ASMJIT_NEW_REG_TYPED #undef ASMJIT_NEW_REG_CUSTOM #undef ASMJIT_NEW_REG_FMT //! \} //! \name Stack //! \{ //!
