+  //! Error handler (pure).
+  //!
+  //! Error handler is called when an error happened. An error can happen in
+  //! many places, but error handler is mostly used by `Assembler` and
+  //! `Compiler` classes to report anything that may cause incorrect code
+  //! generation. There are multiple ways how the error handler can be used
+  //! and each has it's pros/cons.
+  //!
+  //! AsmJit library doesn't use exceptions and can be compiled with or without
+  //! exception handling support. Even if the AsmJit library is compiled without
+  //! exceptions it is exception-safe and handleError() can report an incoming
+  //! error by throwing an exception of any type. It's guaranteed that the
+  //! exception won't be catched by AsmJit and will be propagated to the code
+  //! calling AsmJit `Assembler` or `Compiler` methods. Alternative to
+  //! throwing an exception is using `setjmp()` and `longjmp()` pair available
+  //! in the standard C library.
+  //!
+  //! If the exception or setjmp() / longjmp() mechanism is used, the state of
+  //! the `BaseAssember` or `Compiler` is unchanged and if it's possible the
+  //! execution (instruction serialization) can continue. However if the error
+  //! happened during any phase that translates or modifies the stored code
+  //! (for example relocation done by `Assembler` or analysis/translation
+  //! done by `Compiler`) the execution can't continue and the error will
+  //! be also stored in `Assembler` or `Compiler`.
+  //!
+  //! Finally, if no exceptions nor setjmp() / longjmp() mechanisms were used,
+  //! you can still implement a compatible handling by returning from your
+  //! error handler. Returning `true` means that error was reported and AsmJit
+  //! should continue execution, but `false` sets the rror immediately to the
+  //! `Assembler` or `Compiler` and execution shouldn't continue (this

+
+// This file contains implementation of virtual memory management for AsmJit
+// library. The initial concept is to keep this implementation simple but
+// efficient. There are several goals I decided to write implementation myself.
+//
+// Goals:
+//
+// - Granularity of allocated blocks is different than granularity for a typical
+//   C malloc. It is at least 64-bytes so Assembler/Compiler can guarantee the
+//   alignment required. Alignment requirements can grow in the future, but at
+//   the moment 64 bytes is safe (we may jump to 128 bytes if necessary or make
+//   it configurable).
+//
+// - Keep memory manager information outside of the allocated virtual memory
+//   pages, because these pages allow executing of machine code and there should
+//   not be data required to keep track of these blocks. Another reason is that
+//   some environments (i.e. iOS) allow to generate and run JIT code, but this
+//   code has to be set to [Executable, but not Writable].
+//
+// - Keep implementation simple and easy to follow.
+//
+// Implementation is based on bit arrays and binary trees. Bit arrays contain
+// information related to allocated and unused blocks of memory. The size of
+// a block is described by `MemNode::density`. Count of blocks is stored in
+// `MemNode::blocks`. For example if density is 64 and count of blocks is 20,
+// memory node contains 64*20 bytes of memory and smallest possible allocation
+// (and also alignment) is 64 bytes. So density is also related to memory
+// alignment. Binary trees (RB) are used to enable fast lookup into all addresses
+// allocated by memory manager instance. This is used mainly by `VMemPrivate::release()`.
+//
+// Bit array looks like this (empty = unused, X = used) - Size of block 64:
+//
+//   -------------------------------------------------------------------------
+//   | |X|X| | | | | |X|X|X|X|X|X| | | | | | | | | | | | |X| | | | |X|X|X| | |
+//   -------------------------------------------------------------------------
+//                               (Maximum continuous block)
+//
+// These bits show that there are 12 allocated blocks (X) of 64 bytes, so total
+// size allocated is 768 bytes. Maximum count of continuous memory is 12 * 64.
