# Xbyak 5.78 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
# Xbyak 5.97 ; JIT assembler for x86(IA32), x64(AMD64, x86-64) by C++
## Abstract
This is a header file which enables dynamically to assemble x86(IA32), x64(AMD64, x86-64) mnemonic.
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**: Xbyak uses and(), or(), xor(), not() functions, so `-fno-operator-names` option is necessary for gcc/clang.
**Note**:
Use `and_()`, `or_()`, ... instead of `and()`, `or()`.
If you want to use them, then specify `-fno-operator-names` option to gcc/clang.
Or define `XBYAK_NO_OP_NAMES` before including `xbyak.h` and use and_(), or_(), xor_(), not_() instead of them.
and_(), or_(), xor_(), not_() are always available.
`XBYAK_NO_OP_NAMES` will be defined in the feature version.
### News
- (break backward compatibility) `push(byte, imm)` (resp. `push(word, imm)`) forces to cast `imm` to 8(resp. 16) bit.
- (Windows) `#include <winsock2.h>` 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.

### 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.

### 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.

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()`.
