Returns the calling convention id.

Returns the error `err` passed. Provided for debugging purposes. Putting a breakpoint inside `errored` can help with tracing the origin of any error

Returns the size of the string.

Appends `str` having the given size `size` to the string. Null terminated strings can set `size` to `SIZE_MAX`.

Returns a size of a register or an X86 memory operand. \remarks At the moment only X86 and X86_64 memory operands have a size - other memory operands

Returns the register type.

Returns true if there are no features set.

Tests whether the argument is passed by register.

Returns the associated `BaseCompiler`.

* 将 AArch64 汇编机器码导出为字节数组 ******************************************************************/

Tests whether the logger has the given `flag` enabled.

* 初始化一个独立的 AArch64 汇编环境 ******************************************************************/

Creates a cloned register with element access.

* 在代码中嵌入一个 C 字符串常量，并让 x 指向它 * 参数：a : Assembler 指针 * x : 目标 X 寄存器 * data : 字符串常量 ************************************************************

* 将一个 64bit 常量赋值 X 寄存器： * 参数：a : Assembler 指针 * x : 目标 X 寄存器 * value : 64bit 常量 ****************************************************

Returns the shift amount.

Returns either relative offset or absolute address as 64-bit integer.

getReg - Returns the register number.

Returns the register group.

Tests whether the operand is a memory location (`OperandType::kMem`).

Returns the instruction id with modifiers.

Returns a TypeId of this argument or return value.

Combine `regId` and `vvvvvId` into a single value (used by AVX and AVX-512).

Checks whether all operands have the same signature.

[[pure virtual]]

Reallocates the internal array to fit at least `n` items.

Returns `ZoneAllocator` attached to this container.

Checks whether the register is GP register of the allowed types. Allowed is a 2-bit mask, where the first bits allows GpW and the second bit allows G

Returns the size of the memory operand in bytes. \note Most instructions would deduce the size of the memory operand, so in most cases it's expected

Returns a register type of the register used to pass function argument or return value.

Resizes the vector to hold `n` elements. If `n` is greater than the current size then the additional elements' content will be initialized to zero. I

Append VARIABLE=VALUE\0 string to the buffer, and add a respective * pointer into the vars array. Assumes env != NULL and fmt != NULL. */

Returns the size [in bytes] of `typeId`.

[[pure virtual]]

[[pure virtual]]

Returns the target architecture of this calling convention.

Tests whether the register is a general purpose register (any size).
