// [asmjit::Build - Configuration]
// ============================================================================
// AsmJit is by default compiled only for a host processor for the purpose of
// JIT code generation. Both Assembler and CodeCompiler emitters are compiled
// by default. Preprocessor macros can be used to change the default behavior.

// included.

// AsmJit Static Builds and Embedding
// ----------------------------------
//
// These definitions can be used to enable static library build. Embed is used
// when AsmJit's source code is embedded directly in another project, implies
// static build as well.
//
// #define ASMJIT_EMBED // Asmjit is embedded (implies ASMJIT_STATIC).

// AsmJit Build Modes
// ------------------
//
// These definitions control the build mode and tracing support. The build mode
// should be auto-detected at compile time, but it's possible to override it in
// case that the auto-detection fails.
//
// Tracing is a feature that is never compiled by default and it's only used to
// debug AsmJit itself.
//

// #define ASMJIT_RELEASE // Define to enable release-mode.
// AsmJit Build Backends
// ---------------------
//
// These definitions control which backends to compile. If none of these is
// defined AsmJit will use host architecture by default (for JIT code generation).
//
// #define ASMJIT_BUILD_X86 // Define to enable X86 and X64 code-generation.

// ---------------------

//! Emit optimized code-alignment sequences.
//!
//! Default `true`.
//!
//! X86/X64 Specific
//! ----------------
//!
//! Default align sequence used by X86/X64 architecture is one-byte (0x90)
//! opcode that is often shown by disassemblers as nop. However there are
//! more optimized align sequences for 2-11 bytes that may execute faster.
//! If this feature is enabled AsmJit will generate specialized sequences
//! for alignment between 2 to 11 bytes.
kHintOptimizedAlign = 0x00000001U,
//! Emit jump-prediction hints.
//!
//! Default `false`.
//!
//! X86/X64 Specific
//! ----------------
//!
//! Jump prediction is usually based on the direction of the jump. If the
//! jump is backward it is usually predicted as taken; and if the jump is
//! forward it is usually predicted as not-taken. The reason is that loops
//! generally use backward jumps and conditions usually use forward jumps.
//! However this behavior can be overridden by using instruction prefixes.
//! If this option is enabled these hints will be emitted.
//!
//! This feature is disabled by default, because the only processor that
//! used to take into consideration prediction hints was P4. Newer processors
//! implement heuristics for branch prediction that ignores any static hints.
kHintPredictedJumps = 0x00000002U
};
//! CodeEmitter options that are merged with instruction options.
ASMJIT_ENUM(Options) {
//! Reserved, used to check for errors in `Assembler::_emit()`. In addition,
//! if an emitter is in error state it will have `kOptionMaybeFailureCase`
//! set
kOptionMaybeFailureCase = 0x00000001U,
//! Perform a strict validation before the instruction is emitted.
kOptionStrictValidation = 0x00000002U,
//! Logging is enabled and `CodeHolder::getLogger()` should return a valid
//! \ref Logger pointer.
kOptionLoggingEnabled = 0x00000004U,
//! Mask of all internal options that are not used to represent instruction
//! options, but are used to instrument Assembler and CodeBuilder. These
//! options are internal and should not be used outside of AsmJit itself.
//!
//! NOTE: Reserved options should never appear in `CBInst` options.
kOptionReservedMask = 0x00000007U,
//! Used only by Assembler to mark `_op4` and `_op5` are used.
kOptionOp4Op5Used = 0x00000008U,
//! Prevents following a jump during compilation (CodeCompiler).
kOptionUnfollow = 0x00000010U,
//! Overwrite the destination operand (CodeCompiler).
//!
//! Hint that is important for register liveness analysis. It tells the
//! compiler that the destination operand will be overwritten now or by
//! adjacent instructions. CodeCompiler knows when a register is completely
//! overwritten by a single instruction, for example you don't have to
//! mark "movaps" or "pxor x, x", however, if a pair of instructions is
//! used and the first of them doesn't completely overwrite the content
//! of the destination, CodeCompiler fails to mark that register as dead.
//!
//! X86/X64 Specific
//! ----------------
//!
//! - All instructions that always overwrite at least the size of the
//! register the virtual-register uses , for example "mov", "movq",
//! "movaps" don't need the overwrite option to be used - conversion,
//! shuffle, and other miscellaneous instructions included.
//!
//! - All instructions that clear the destination register if all operands
//! are the same, for example "xor x, x", "pcmpeqb x x", etc...
//!
//! - Consecutive instructions that partially overwrite the variable until
//! there is no old content require the `overwrite()` to be used. Some
//! examples (not always the best use cases thought):
//!
//! - `movlps xmm0, ?` followed by `movhps xmm0, ?` and vice versa
//! - `movlpd xmm0, ?` followed by `movhpd xmm0, ?` and vice versa
//! - `mov al, ?` followed by `and ax, 0xFF`
//! - `mov al, ?` followed by `mov ah, al`
//! - `pinsrq xmm0, ?, 0` followed by `pinsrq xmm0, ?, 1`
//!
//! - If allocated variable is used temporarily for scalar operations. For
//! example if you allocate a full vector like `X86Compiler::newXmm()`
//! and then use that vector for scalar operations you should use
//! `overwrite()` directive:
//!
//! - `sqrtss x, y` - only LO element of `x` is changed, if you don't use
//! HI elements, use `X86Compiler.overwrite().sqrtss(x, y)`.

//! Error handler (abstract).
//!
//! Error handler is called after an error happened and before it's propagated
//! to the caller. There are multiple ways how the error handler can be used:
//!
//! 1. Returning `true` or `false` from `handleError()`. If `true` is returned
//! it means that the error was reported and AsmJit can continue execution.
//! The reported error still be propagated to the caller, but won't put the
//! CodeEmitter into an error state (it won't set last-error). However,
//! returning `false` means that the error cannot be handled - in such case
//! it stores the error, which can be then retrieved by using `getLastError()`.
//! Returning `false` is the default behavior when no error handler is present.
//! To put the assembler into a non-error state again a `resetLastError()` must
//! be called.
//!
//! 2. Throwing an exception. AsmJit doesn't use exceptions and is completely
//! exception-safe, but you can throw exception from your error handler if
//! this way is the preferred way of handling errors in your project. Throwing
//! an exception acts virtually as returning `true` as AsmJit won't be able
//! to store the error because the exception changes execution path.
//!
//! 3. Using plain old C's `setjmp()` and `longjmp()`. Asmjit always puts
//! `CodeEmitter` to a consistent state before calling the `handleError()`
//! so `longjmp()` can be used without any issues to cancel the code
//! generation if an error occurred. There is no difference between
//! exceptions and longjmp() from AsmJit's perspective.

// AsmJit Static Builds and Embedding
// ----------------------------------
//
// These definitions can be used to enable static library build. Embed is used
// when AsmJit's source code is embedded directly in another project, implies
// static build as well.
//
// #define ASMJIT_EMBED // Asmjit is embedded (implies ASMJIT_BUILD_STATIC).
// #define ASMJIT_STATIC // Enable static-library build.
// AsmJit Build Mode
// -----------------
//
// These definitions control the build mode and tracing support. The build mode
// should be auto-detected at compile time, but it's possible to override it in
// case that the auto-detection fails.
//
// Tracing is a feature that is never compiled by default and it's only used to
// debug AsmJit itself.
//
// #define ASMJIT_BUILD_DEBUG // Always use debug-mode (ASMJIT_ASSERT enabled).
// #define ASMJIT_BUILD_RELEASE // Always use release-mode (ASMJIT_ASSERT disabled).
// AsmJit Build Backends
// ---------------------
//
// These definitions control which backends to compile. If none of these is
// defined AsmJit will use host architecture by default (for JIT code generation).
//
// #define ASMJIT_BUILD_X86 // Enable X86 targets (X86 and X86_64).
// #define ASMJIT_BUILD_ARM // Enable ARM targets (ARM and AArch64).
// #define ASMJIT_BUILD_HOST // Enable targets based on target arch (default).
// AsmJit Build Options
// --------------------
//
// Flags can be defined to disable standard features. These are handy especially
// when building AsmJit statically and some features are not needed or unwanted
// (like BaseCompiler).
//
// AsmJit features are enabled by default.
// #define ASMJIT_NO_BUILDER // Disable Builder (completely).
// #define ASMJIT_NO_COMPILER // Disable Compiler (completely).
// #define ASMJIT_NO_JIT // Disable JIT memory manager and JitRuntime.

// #define ASMJIT_NO_TEXT // Disable everything that contains text
// // representation (instructions, errors, ...).
// #define ASMJIT_NO_VALIDATION // Disable validation API and options.

// // (validation, cpu features, rw-info, etc).

//! 3. Using plain old C's `setjmp()` and `longjmp()`. Asmjit always puts
//! `BaseEmitter` to a consistent state before calling `handleError()`
//! so `longjmp()` can be used without any issues to cancel the code
//! generation if an error occurred. There is no difference between
