CONSTANTS

Type

Each register has a type, which is a read only property. The following values are supported:

SIRTX::VM::Register::TYPE_USER()

The register is a user register. It's meaning is defined by the user/application.

SIRTX::VM::Register::TYPE_SYSTEM()

The register is a system register. It's meaning is defined by the formal specification and must not be used in any other way.

Owner

Each register has a owner. The owner is a read-write property that defines who currently owns the register.

SIRTX::VM::Register::OWNER_MINE()

The register is owned by the user/application. The application may use the register anyway it pleases.

This is the default.

SIRTX::VM::Register::OWNER_YOURS()

The register is currently owned by the assembler. The assembler is free to use the register as sees fit. The user/application is not allowed to alter the content of the register (unless specifically documented).

SIRTX::VM::Register::OWNER_THEIRS()

The register is owned by external code (such as a library). Both user/application and assembler are not allowed to alter the register.

Temperature

The register temperature tells how much a register is currently used. This is a read-write property. This is used by the assembler to optimise code.

SIRTX::VM::Register::TEMPERATURE_COLD()

The register is currently not or only rarely used.

SIRTX::VM::Register::TEMPERATURE_LUKEWARM()

The register is used sometimes.

This is the default.

SIRTX::VM::Register::TEMPERATURE_HOT()

The register is currently in active use.
