[![Build Status](https://travis-ci.org/herumi/xbyak.png)](https://travis-ci.org/herumi/xbyak) # Xbyak 5.96 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++ ## Abstract Xbyak is a C++ header library that enables dynamically to assemble x86(IA32), x64(AMD64, x86-64) mnemonic. ## Feature * header file only * Intel/MASM like syntax * fully support AVX-512 **Note**: Use `and_()`, `or_()`, ... instead of `and()`, `or()`. If you want to use them, then specify `-fno-operator-names` option to gcc/clang. ### News - (break backward compatibility) `push(byte, imm)` (resp. `push(word, imm)`) forces to cast `imm` to 8(resp. 16) bit. - (Windows) `#include ` has been removed from xbyak.h, so add it explicitly if you need it. - support exception-less mode see. [Exception-less mode](#exception-less-mode) - `XBYAK_USE_MMAP_ALLOCATOR` will be defined on Linux/macOS unless `XBYAK_DONT_USE_MMAP_ALLOCATOR` is defined. ### Supported OS * Windows Xp, Vista, Windows 7, Windows 10(32bit, 64bit) * Linux(32bit, 64bit) * Intel macOS ### Supported Compilers Almost C++03 or later compilers for x86/x64 such as Visual Studio, g++, clang++, Intel C++ compiler and g++ on mingw/cygwin. ## Install The following files are necessary. Please add the path to your compile directory. * xbyak.h * xbyak_mnemonic.h * xbyak_util.h Linux: ``` make install ``` These files are copied into `/usr/local/include/xbyak`. ## How to use it Inherit `Xbyak::CodeGenerator` class and make the class method. ``` #include struct Code : Xbyak::CodeGenerator { Code(int x) { mov(eax, x); ret(); } }; ``` Or you can pass the instance of CodeGenerator without inheriting. ``` void genCode(Xbyak::CodeGenerator& code, int x) { using namespace Xbyak::util; code.mov(eax, x); code.ret(); } ``` Make an instance of the class and get the function pointer by calling `getCode()` and call it. ``` Code c(5); int (*f)() = c.getCode(); printf("ret=%d\n", f()); // ret = 5 ``` ## Syntax Similar to MASM/NASM syntax with parentheses. ``` NASM Xbyak mov eax, ebx --> mov(eax, ebx); inc ecx inc(ecx); ret --> ret(); ``` ## Addressing Use `qword`, `dword`, `word` and `byte` if it is necessary to specify the size of memory, otherwise use `ptr`. ``` (ptr|qword|dword|word|byte) [base + index * (1|2|4|8) + displacement] [rip + 32bit disp] ; x64 only NASM Xbyak mov eax, [ebx+ecx] --> mov(eax, ptr [ebx+ecx]); mov al, [ebx+ecx] --> mov(al, ptr [ebx + ecx]); test byte [esp], 4 --> test(byte [esp], 4); inc qword [rax] --> inc(qword [rax]); ``` **Note**: `qword`, ... are member variables, then don't use `dword` as unsigned int type. ### How to use Selector (Segment Register) ``` mov eax, [fs:eax] --> putSeg(fs); mov(eax, ptr [eax]); mov ax, cs --> mov(ax, cs); ``` **Note**: Segment class is not derived from `Operand`. ## AVX ``` vaddps(xmm1, xmm2, xmm3); // xmm1 <- xmm2 + xmm3 vaddps(xmm2, xmm3, ptr [rax]); // use ptr to access memory vgatherdpd(xmm1, ptr [ebp + 256 + xmm2*4], xmm3); ``` **Note**: If `XBYAK_ENABLE_OMITTED_OPERAND` is defined, then you can use two operand version for backward compatibility. But the newer version will not support it. ``` vaddps(xmm2, xmm3); // xmm2 <- xmm2 + xmm3 ``` ## AVX-512 ``` vaddpd zmm2, zmm5, zmm30 --> vaddpd(zmm2, zmm5, zmm30); vaddpd xmm30, xmm20, [rax] --> vaddpd(xmm30, xmm20, ptr [rax]); vaddps xmm30, xmm20, [rax] --> vaddps(xmm30, xmm20, ptr [rax]); vaddpd zmm2{k5}, zmm4, zmm2 --> vaddpd(zmm2 | k5, zmm4, zmm2); vaddpd zmm2{k5}{z}, zmm4, zmm2 --> vaddpd(zmm2 | k5 | T_z, zmm4, zmm2); vaddpd zmm2{k5}{z}, zmm4, zmm2,{rd-sae} --> vaddpd(zmm2 | k5 | T_z, zmm4, zmm2 | T_rd_sae); vaddpd(zmm2 | k5 | T_z | T_rd_sae, zmm4, zmm2); // the position of `|` is arbitrary. vcmppd k4{k3}, zmm1, zmm2, {sae}, 5 --> vcmppd(k4 | k3, zmm1, zmm2 | T_sae, 5); vaddpd xmm1, xmm2, [rax+256] --> vaddpd(xmm1, xmm2, ptr [rax+256]); vaddpd xmm1, xmm2, [rax+256]{1to2} --> vaddpd(xmm1, xmm2, ptr_b [rax+256]); vaddpd ymm1, ymm2, [rax+256]{1to4} --> vaddpd(ymm1, ymm2, ptr_b [rax+256]); vaddpd zmm1, zmm2, [rax+256]{1to8} --> vaddpd(zmm1, zmm2, ptr_b [rax+256]); vaddps zmm1, zmm2, [rax+rcx*8+8]{1to16} --> vaddps(zmm1, zmm2, ptr_b [rax+rcx*8+8]); vmovsd [rax]{k1}, xmm4 --> vmovsd(ptr [rax] | k1, xmm4); vcvtpd2dq xmm16, oword [eax+33] --> vcvtpd2dq(xmm16, xword [eax+33]); // use xword for m128 instead of oword vcvtpd2dq(xmm16, ptr [eax+33]); // default xword vcvtpd2dq xmm21, [eax+32]{1to2} --> vcvtpd2dq(xmm21, ptr_b [eax+32]); vcvtpd2dq xmm0, yword [eax+33] --> vcvtpd2dq(xmm0, yword [eax+33]); // use yword for m256 vcvtpd2dq xmm19, [eax+32]{1to4} --> vcvtpd2dq(xmm19, yword_b [eax+32]); // use yword_b to broadcast vfpclassps k5{k3}, zword [rax+64], 5 --> vfpclassps(k5|k3, zword [rax+64], 5); // specify m512 vfpclasspd k5{k3}, [rax+64]{1to2}, 5 --> vfpclasspd(k5|k3, xword_b [rax+64], 5); // broadcast 64-bit to 128-bit vfpclassps k5{k3}, [rax+64]{1to4}, 5 --> vfpclassps(k5|k3, yword_b [rax+64], 5); // broadcast 64-bit to 256-bit ``` ### Remark * `k1`, ..., `k7` are opmask registers. - `k0` is dealt as no mask. - e.g. `vmovaps(zmm0|k0, ptr[rax]);` and `vmovaps(zmm0|T_z, ptr[rax]);` are same to `vmovaps(zmm0, ptr[rax]);`. * use `| T_z`, `| T_sae`, `| T_rn_sae`, `| T_rd_sae`, `| T_ru_sae`, `| T_rz_sae` instead of `,{z}`, `,{sae}`, `,{rn-sae}`, `,{rd-sae}`, `,{ru-sae}`, `,{rz-sae}` respectively. * `k4 | k3` is different from `k3 | k4`. * use `ptr_b` for broadcast `{1toX}`. X is automatically determined. * specify `xword`/`yword`/`zword(_b)` for m128/m256/m512 if necessary. ## Label Two kinds of Label are supported. (String literal and Label class). ### String literal ``` L("L1"); jmp("L1"); jmp("L2"); ... a few mnemonics (8-bit displacement jmp) ... L("L2"); jmp("L3", T_NEAR); ... a lot of mnemonics (32-bit displacement jmp) ... L("L3"); ``` * Call `hasUndefinedLabel()` to verify your code has no undefined label. * you can use a label for immediate value of mov like as `mov(eax, "L2")`. ### Support `@@`, `@f`, `@b` like MASM ``` L("@@"); // jmp("@b"); // jmp to jmp("@f"); // jmp to L("@@"); // jmp("@b"); // jmp to mov(eax, "@b"); jmp(eax); // jmp to ``` ### Local label Label symbols beginning with a period between `inLocalLabel()` and `outLocalLabel()` are treated as a local label. `inLocalLabel()` and `outLocalLabel()` can be nested. ``` void func1() { inLocalLabel(); L(".lp"); // ; local label ... jmp(".lp"); // jmp to L("aaa"); // global label outLocalLabel(); inLocalLabel(); L(".lp"); // ; local label func1(); jmp(".lp"); // jmp to inLocalLabel(); jmp("aaa"); // jmp to } ``` ### short and long jump Xbyak deals with jump mnemonics of an undefined label as short jump if no type is specified. So if the size between jmp and label is larger than 127 byte, then xbyak will cause an error. ``` jmp("short-jmp"); // short jmp // small code L("short-jmp"); jmp("long-jmp"); // long code L("long-jmp"); // throw exception ``` Then specify T_NEAR for jmp. ``` jmp("long-jmp", T_NEAR); // long jmp // long code L("long-jmp"); ``` Or call `setDefaultJmpNEAR(true);` once, then the default type is set to T_NEAR. ``` jmp("long-jmp"); // long jmp // long code L("long-jmp"); ``` ### Label class `L()` and `jxx()` support Label class. ``` Xbyak::Label label1, label2; L(label1); ... jmp(label1); ... jmp(label2); ... L(label2); ``` Use `putL` for jmp table ``` Label labelTbl, L0, L1, L2; mov(rax, labelTbl); // rdx is an index of jump table jmp(ptr [rax + rdx * sizeof(void*)]); L(labelTbl); putL(L0); putL(L1); putL(L2); L(L0); .... L(L1); .... ``` `assignL(dstLabel, srcLabel)` binds dstLabel with srcLabel. ``` Label label2; Label label1 = L(); // make label1 ; same to Label label1; L(label1); ... jmp(label2); // label2 is not determined here ... assignL(label2, label1); // label2 <- label1 ``` The `jmp` in the above code jumps to label1 assigned by `assignL`. **Note**: * srcLabel must be used in `L()`. * dstLabel must not be used in `L()`. `Label::getAddress()` returns the address specified by the label instance and 0 if not specified. ``` // not AutoGrow mode Label label; assert(label.getAddress() == 0); L(label); assert(label.getAddress() == getCurr()); ``` ### Rip ; relative addressing ``` Label label; mov(eax, ptr [rip + label]); // eax = 4 ... L(label); dd(4); ``` ``` int x; ... mov(eax, ptr[rip + &x]); // throw exception if the difference between &x and current position is larger than 2GiB ``` ## Code size The default max code size is 4096 bytes. Specify the size in constructor of `CodeGenerator()` if necessary. ``` class Quantize : public Xbyak::CodeGenerator { public: Quantize() : CodeGenerator(8192) { } ... }; ``` ## User allocated memory You can make jit code on prepaired memory. Call `setProtectModeRE` yourself to change memory mode if using the prepaired memory. ``` uint8_t alignas(4096) buf[8192]; // C++11 or later struct Code : Xbyak::CodeGenerator { Code() : Xbyak::CodeGenerator(sizeof(buf), buf) { mov(rax, 123); ret(); } }; int main() { Code c; c.setProtectModeRE(); // set memory to Read/Exec printf("%d\n", c.getCode()()); } ``` **Note**: See [sample/test0.cpp](sample/test0.cpp). ### AutoGrow The memory region for jit is automatically extended if necessary when `AutoGrow` is specified in a constructor of `CodeGenerator`. Call `ready()` or `readyRE()` before calling `getCode()` to fix jump address. ``` struct Code : Xbyak::CodeGenerator { Code() : Xbyak::CodeGenerator(, Xbyak::AutoGrow) { ... } }; Code c; // generate code for jit c.ready(); // mode = Read/Write/Exec ``` **Note**: * Don't use the address returned by `getCurr()` before calling `ready()` because it may be invalid address. ### Read/Exec mode Xbyak set Read/Write/Exec mode to memory to run jit code. If you want to use Read/Exec mode for security, then specify `DontSetProtectRWE` for `CodeGenerator` and call `setProtectModeRE()` after generating jit code. ``` struct Code : Xbyak::CodeGenerator { Code() : Xbyak::CodeGenerator(4096, Xbyak::DontSetProtectRWE) { mov(eax, 123); ret(); } }; Code c; c.setProtectModeRE(); ... ``` Call `readyRE()` instead of `ready()` when using `AutoGrow` mode. See [protect-re.cpp](sample/protect-re.cpp). ## Exception-less mode If `XBYAK_NO_EXCEPTION` is defined, then gcc/clang can compile xbyak with `-fno-exceptions`. In stead of throwing an exception, `Xbyak::GetError()` returns non-zero value (e.g. `ERR_BAD_ADDRESSING`) if there is something wrong. The status will not be changed automatically, then you should reset it by `Xbyak::ClearError()`. `CodeGenerator::reset()` calls `ClearError()`. ## Macro * **XBYAK32** is defined on 32bit. * **XBYAK64** is defined on 64bit. * **XBYAK64_WIN** is defined on 64bit Windows(VC). * **XBYAK64_GCC** is defined on 64bit gcc, cygwin. * define **XBYAK_USE_OP_NAMES** on gcc with `-fno-operator-names` if you want to use `and()`, .... * define **XBYAK_ENABLE_OMITTED_OPERAND** if you use omitted destination such as `vaddps(xmm2, xmm3);`(deprecated in the future). * define **XBYAK_UNDEF_JNL** if Bessel function jnl is defined as macro. * define **XBYAK_NO_EXCEPTION** for a compiler option `-fno-exceptions`. ## Sample * [test0.cpp](sample/test0.cpp) ; tiny sample (x86, x64) * [quantize.cpp](sample/quantize.cpp) ; JIT optimized quantization by fast division (x86 only) * [calc.cpp](sample/calc.cpp) ; assemble and estimate a given polynomial (x86, x64) * [bf.cpp](sample/bf.cpp) ; JIT brainfuck (x86, x64) ## License modified new BSD License http://opensource.org/licenses/BSD-3-Clause ## History * 2020/Aug/28 ver 5.95 some constructors of register classes support constexpr if C++14 or later * 2020/Aug/04 ver 5.941 `CodeGenerator::reset()` calls `ClearError()`. * 2020/Jul/28 ver 5.94 remove #include (only windows) * 2020/Jul/21 ver 5.93 support exception-less mode * 2020/Jun/30 ver 5.92 support Intel AMX instruction set (Thanks to nshustrov) * 2020/Jun/22 ver 5.913 fix mov(r64, imm64) on 32-bit env with XBYAK64 * 2020/Jun/19 ver 5.912 define MAP_JIT on macOS regardless of Xcode version (Thanks to rsdubtso) * 2020/May/10 ver 5.911 XBYAK_USE_MMAP_ALLOCATOR is defined unless XBYAK_DONT_USE_MMAP_ALLOCATOR is defined. * 2020/Apr/20 ver 5.91 accept mask register k0 (it means no mask) * 2020/Apr/09 ver 5.90 kmov{b,d,w,q} throws exception for an unsupported register * 2020/Feb/26 ver 5.891 fix typo of type * 2020/Jan/03 ver 5.89 fix error of vfpclasspd * 2019/Dec/20 ver 5.88 fix compile error on Windows * 2019/Dec/19 ver 5.87 add setDefaultJmpNEAR(), which deals with `jmp` of an undefined label as T_NEAR if no type is specified. * 2019/Dec/13 ver 5.86 [changed] revert to the behavior before v5.84 if -fno-operator-names is defined (and() is available) * 2019/Dec/07 ver 5.85 append MAP_JIT flag to mmap for macOS mojave or later * 2019/Nov/29 ver 5.84 [changed] XBYAK_NO_OP_NAMES is defined unless XBYAK_USE_OP_NAMES is defined * 2019/Oct/12 ver 5.83 exit(1) was removed * 2019/Sep/23 ver 5.82 support monitorx, mwaitx, clzero (thanks to @MagurosanTeam) * 2019/Sep/14 ver 5.81 support some generic mnemonics. * 2019/Aug/01 ver 5.802 fix detection of AVX512_BF16 (thanks to vpirogov) * 2019/May/27 support vp2intersectd, vp2intersectq (not tested) * 2019/May/26 ver 5.80 support vcvtne2ps2bf16, vcvtneps2bf16, vdpbf16ps * 2019/Apr/27 ver 5.79 vcmppd/vcmpps supports ptr_b(thanks to jkopinsky) * 2019/Apr/15 ver 5.78 rewrite Reg::changeBit() (thanks to MerryMage) * 2019/Mar/06 ver 5.77 fix number of cores that share LLC cache by densamoilov * 2019/Jan/17 ver 5.76 add Cpu::getNumCores() by shelleygoel * 2018/Oct/31 ver 5.751 recover Xbyak::CastTo for compatibility * 2018/Oct/29 ver 5.75 unlink LabelManager from Label when msg is destroyed * 2018/Oct/21 ver 5.74 support RegRip +/- int.
