• not all of the types described in the C99 standard are required to be defined by conformant implementations nor is it possible for all devices to implement some of the types specified (e.g., int8_t is not implemented on C54 devices); so it is difficult to identify non-portable source code.
• not all compilers provide C99 type support; if XDC supplies the type definition and the compiler is updated to include C99 types, a compilation error will occur if the source includes the C99 headers.
• not all compiler and device combinations are conformant; even high quality compilers may not properly define the types for each device supported by compiler.

      #include <xdc/std.h>

xdc_target_types__

the package qualified path of the target's standard types header; e.g., ti/targets/std.h. This value is specified in the target's stdInclude config parameter; see xdc.bld.ITarget.stdInclude

xdc_target_name__

the target's module name without the package prefix; e.g., C64 rather than ti.targets.C64.

      cl6x -Dxdc_target_types__=ti/targets/std.h -Dxdc_target_name__=C64

      #define xdc__nolocalnames
      #include <xdc/std.h>

Bool

this type is large enough to hold the values 0 or 1. The constants TRUE and FALSE are of this type; see below.

String

this type is defined to be a char * and exists to allow code to distinguish between pointers to buffers of raw data and '\0' terminated strings.

Intn, where n = 8, 16, or 32

signed integer type that is large enough to hold n bits; the actual target type may by be larger than n. This type is equivalent to one of the C99 types int_leastn_t or int_fastn_t; see Section 7.18.

UIntn, where n = 8, 16, or 32

unsigned integer type that is large enough to hold n bits; the actual target type may by be larger than n. This type is equivalent to one of the C99 types uint_leastn_t or uint_fastn_t; see ISO/IEC 9899:1999 Section 7.18.

Bitsn, where n = 8, 16, or 32

unsigned integer type that is precisely n bits. Not all targets support all values of n; if the target does not support an exact size the corresponding type is not defined. This type is equivalent to the corresponding C99 type uintn_t; see ISO/IEC 9899:1999 Section 7.18.

Fxn

this type is a pointer to code; it can hold a pointer to any function.

Ptr

this type is a pointer to data; it can hold a pointer to any data structure.

IArg

this integer type is large enough to hold a Fxn, Ptr, or Int.

UArg

this unsigned integer type is large enough to hold a Fxn, Ptr, or Int.

LLong

this long integer type is large enough to hold a Long and is defined as a 'long long' type on targets that support this type; otherwise, it is simply a Long. Note that C99 requires the long long type to be at least 64-bits wide (See ISO/IEC 9899:1999 Section 5.2.4.2.1). But some compilers do not support 64-bit integral types and some don't support the long long even though they do support 64-bit integral types. Since these variations limit the portability of valid C sources, the LLong type is always defined, is always at least as wide as the Long type, and is at least 64-bits wide for targets that support 64-bit integral types.

ULLong

this unsigned long integer type is large enough to hold a ULong and is defined as a 'unsigned long long' type on targets that support this type; otherwise, it is simply a ULong.

Char and UChar

aliases for char and unsigned char, respectively

Short and UShort

aliases for short and unsigned short, respectively

Int and UInt

aliases for int and unsigned int, respectively

Long and ULong

aliases for long and unsigned long, respectively

Double and LDouble

aliases for double and long double, respectively

SizeT

alias for size_t

VaList

alias for va_list

Bitsn, where n = 8, 16, or 32

this unsigned integer type is precisely n-bits wide. This type is equivalent to the optional C99 type uintn_t; see ISO/IEC 9899:1999 Section 7.18.1.1. This type is defined if and only if the preprocessor macro xdc__BITSn__ is defined.

Int64

signed integer type that is large enough to hold 64 bits; the actual target type may by be wider than 64 bits. This type is equivalent to one of the C99 types int_least64_t or int_fast64_t; see Section 7.18. This type is defined if and only if the preprocessor macro xdc__INT64__ is defined.

UInt64

unsigned integer type that is large enough to hold n bits; the actual target type may by be wider than 64 bits. This type is equivalent to one of the C99 types uint_least64_t or uint_fast64_t; see ISO/IEC 9899:1999 Section 7.18. This type is defined if and only if the preprocessor macro xdc__INT64__ is defined.

Bits64

unsigned integer type that is precisely 64 bits wide. If the target does not support an exact 64-bit size, this type is not defined. This type is equivalent to the corresponding C99 type uint64_t; see ISO/IEC 9899:1999 Section 7.18. This type is defined if and only if the preprocessor macro xdc__BITS64__ is defined.

NULL

defined as 0

TRUE

defined as ((Bool)1)

FALSE

defined as ((Bool)0)

{c_target_name}

this symbol (the target's fully qualified name with all '.'s replaced with '_') is always defined and allows one to easily include target-specific headers or define symbols with target-specific values.

xdc_target__isaCompatible_{isa_name}

for every ISA named in the array returned by this target's xdc.bld.ITarget.getISAChain() method, a symbol of this name is defined. In addition to enabling one to create code specific to a particular ISA, this allows one to create code that depends on TI's C6x architecture without being dependent on a particular member of the C6x family, for example.

xdc_target__isa_{isa}

this symbol is always defined and {isa} is the target's isa (see xdc.bld.ITarget.isa).

xdc_target__{little,big}Endian

if this target's xdc.bld.ITarget.model.endian property is specified, this symbol is defined and {little,big} is replaced by model.endian.

xdc_target__{code_model_name}Code

if this target's xdc.bld.ITarget.model.codeModel is specified, this symbol is defined and {code_model_name} is replaced by model.codeModel.

xdc_target__{data_model_name}Data

if this target's xdc.bld.ITarget.model.dataModel is specified, this symbol is defined and {data_model_name} is replaced by model.dataModel.

xdc_target__os_{os_name}

this symbol is always defined and {os_name} is the target's os name (see xdc.bld.ITarget.os).

xdc_target__sizeof_{type_name}

this symbol is defined for each type name supported in the target's xdc.bld.ITarget.stdTypes structure, {type_name} is the name of one of the standard types supported above, and the value is sizeof(type_name).

xdc_target__alignof_{type_name}

this symbol is defined for each type name supported in the target's xdc.bld.ITarget.stdTypes structure, {type_name} is the name of one of the standard types supported above, and the value is the alignment required by the compiler for {type_name}.

xdc_target__bitsPerChar

this symbol is always defined and specifies the number of bits in the target's char. This value combined with the xdc_target__sizeof_ values allows C code to determine the precise number of bits in any of the standard types.

xdc.PACKAGE_NOT_FOUND

This error is reported whenever a specified package is not found This may happen for the following reasons:

• Ensure that the package in question is contained in one of the repositories named in the package path.
• The package has not been built by the xdc tool even though the physical package directory may be present along the package path

xdc.FILE_NOT_FOUND

This error is reported when a specified file is not found. Ensure that any directory name prefix in the name is a package directory contained in one of the repositories named in the package path. For example, if "ti/targets/linkcmd.xdt" can't be found, make sure the directory ti/targets/ is contained in at least one repository named in the package path.

xdc.MODULE_NOT_FOUND

This error is reported when a specified module can't be found. Ensure that the package containing the module in question is contained in at least one repository named in the package path. Also ensure that the module name is qualified with the package name. For example, to refer to the module Engine in the package ti.sdo.ce, the module name should be specified as ti.sdo.ce.Engine.

xdc.TOOL_USAGE_ERROR

This error may happen when the xs tool is not passed the expected command line arguments.

xdc.MODULE_UNDEFINED_MAIN_FUNCTION

This error is reported when the xs tool is passed a module that does not define a main function. Ensure that the meta-domain implementation of the module has a main function.

xdc.SPEC_FILE_ERROR

This error is reported when there is a parsing error in a specification file. Check the spec. file for syntax errors.

xdc.DEPRECATED_FUNCTION

This error is reported whenever a deprecated function is called.

xdc.STATIC_INSTANCE

This error is reported when a function create() is called at the configuration time for a module that does not implement the function instance$static$init and therefore does not support static instances.
