Language Specification (C) : Target Parameters

Target Parameters

Module Trgt provides target specific constants. Its provision is mandatory. Where any of the required constants are dependent on user selectable compiler options, the module may be implemented as a built-in module.

Identity

Constant	Type	Meaning
ShortName	String Literal	short name of the target
LongName	String Literal	long name of the target
MajorVersion	Whole Number	major version of the code generator for this target
MinorVersion	Whole Number	minor version of the code generator for this target
SubMinorVersion	Whole Number	sub-minor version of the code generator for this target

Classification

Boolean Constant	indicates whether target ...
IsProcessor	is a hardware architecture
IsVirtualProcessor	is a processor independent assembler backend
IsVirtualMachineHost	is a virtual machine host and runtime environment
IsHigherLevelLanguage	is a language processor for a higher level programming language

Characteristics

Boolean Constant	indicates whether ...
IsBigEndian	target uses big-endian byte order
IsLittleEndian	target uses little-endian byte order
SupportsAO	code generator supports atomic operations for this target
SupportsTCE	code generator supports tail call elimination for this target
