Utilities

Utility classes and functions.

Overview

AsmJit uses and provides utility classes and functions, that can be used with AsmJit. The functionality can be divided into the following topics:

String Functionality

• String - AsmJit's string container, which is used internally and which doesn't use exceptions and has a stable layout, which is not dependent on C++ standard library.
• StringTmp - String that can have base storage allocated on stack. The amount of storage on stack can be specified as a template parameter.
• FixedString - Fixed string container limited up to N characters.

Code Generation Utilities

• ConstPool - Constant pool used by BaseCompiler, but also available to users that may find use of it.

Support Functionality Used by AsmJit

• Support namespace provides many other utility functions and classes that are used by AsmJit, and made public.

Enumerations

enum class ConstPoolScope : uint32_t

enum class StringFormatFlags : uint32_t

class ConstPoolScope : uint32_tenumstrong

Constant pool scope.

Constant	Description
kLocal	Local constant, always embedded right after the current function.
kGlobal	Global constant, embedded at the end of the currently compiled code.
kMaxValue	Maximum value of ConstPoolScope.

class StringFormatFlags : uint32_tenumstrong

Format flags used by String API.

Constant	Description
kNone	No flags.
kShowSign	Show sign.
kShowSpace	Show space.
kAlternate	Alternate form (use 0x when formatting HEX number).
kSigned	The input is signed.
