[BA]: https://bytecodealliance.org/
WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (WASM) runtime with small footprint, high performance and highly configurable features for applications cross from embedded, IoT, edge to Trusted Execution Environment (TEE), smart contract, cloud native and so on. It includes a few parts as below:
- The [**"iwasm" VM core**](./README.md#iwasm-vm-core) to run WASM applications, supporting interpreter mode, AOT mode (Ahead-of-Time compilation) and JIT mode (Just-in-Time compilation)
- The [**"iwasm" VM core**](./README.md#iwasm-vm-core) to run WASM applications, supporting interpreter mode, AOT mode (Ahead-of-Time compilation) and JIT modes (Just-in-Time compilation, LLVM JIT and Fast JIT are supported)
- The [**"wamrc" AOT compiler**](./README.md#build-wamrc-aot-compiler) to compile WASM file into AOT file for best performance and smaller runtime footprint, which is run by "iwasm" VM Core

*
* @brief Definition of JIT IR instructions and annotations.
*/
/**
* @def INSN (NAME, OPND_KIND, OPND_NUM, FIRST_USE)
*
* Definition of IR instructions
*
* @param NAME name of the opcode
* @param OPND_KIND kind of the operand(s)
* @param OPND_NUM number of the operand(s)
* @param FIRST_USE index of the first use register
*
* @p OPND_KIND and @p OPND_NUM together determine the format of an
* instruction. There are four kinds of formats:
*
* 1) Reg: fixed-number register operands, @p OPND_NUM specifies the
* number of operands;
*
* 2) VReg: variable-number register operands, @p OPND_NUM specifies
* the number of fixed register operands;
*
* 3) TableSwitch: tableswitch instruction's format, @p OPND_NUM must
* be 1;
*
* 4) LookupSwitch: lookupswitch instruction's format, @p OPND_NUM
* must be 1.
*
* Instruction operands are all registers and they are organized in an
* order that all registers defined by the instruction, if any, appear
* before the registers used by the instruction. The @p FIRST_USE is
* the index of the first use register in the register vector sorted
* in this order. Use @c jit_insn_opnd_regs to get the register
* vector in this order and use @c jit_insn_opnd_first_use to get the
* index of the first use register.
*
* Every instruction with name @p NAME has the following definitions:
*
* @c JEFF_OP_NAME: the enum opcode of insn NAME
* @c jit_insn_new_NAME (...): creates a new instance of insn NAME
*
* An instruction is deleted by function:
*
* @c jit_insn_delete (@p insn)
*
* In the scope of this IR's terminology, operand and argument have
* different meanings. The operand is a general notation, which
* denotes every raw operand of an instruction, while the argument
* only denotes the variable part of operands of instructions of VReg
* kind. For example, a VReg instruction phi node "r0 = phi(r1, r2)"
* has three operands opnd[0]: r0, opnd[1]: r1 and opnd[2]: r2, but
* only two arguments arg[0]: r1 and arg[1]: r2. Operands or
* arguments of instructions with various formats can be access
* through the following APIs:
*
* @c jit_insn_opnd (@p insn, @p n): for Reg_N formats
* @c jit_insn_opndv (@p insn, @p n): for VReg_N formats
* @c jit_insn_opndv_num (@p insn): for VReg_N formats
* @c jit_insn_opndts (@p insn): for TableSwitch_1 format
* @c jit_insn_opndls (@p insn): for LookupSwitch_1 format
