Interfaces Compiler

gcc

The GNU gcc is available for many platforms and targets. In the section below we concentrate on the compiler bridge for a PowerPC.

Description

WSTCompiler.h

This file defines the following types:

RiCBoolean	myboolean (see note below)
timeUnit	unint32
RiCHandle	sint8
gen_ptr	void *
eventID_t	sint16

This file defines the following macros:

WST_TM_OVERFLOW	INT_MAX
MALLOC_ARGUMENT_TYPE	size_t
MALLOC_RETURN_TYPE	void *
FREE_ARGUMENT_TYPE	void *
FREE_RETURN_TYPE	void
TRUE	1
FALSE	0
WST_NEARD
WST_FARD
WST_NEARC
WST_FARC
WST_NEARD_ADDRESS_SIZE¹	32
WST_FARD_ADDRESS_SIZE¹	32
WST_NEARC_ADDRESS_SIZE¹	32
WST_FARC_ADDRESS_SIZE¹	32
WST_TIMEUNIT_ADDRESS_SIZE¹	32
RIC_OS_TOLOWER_DEFINED_IN_CTYPE

RiC_UINT64	unsigned long
RiC_INT32_MIN	(sint32) INT_MIN
RiC_INT32_MAX	(sint32) INT_MAX
RhpPositive_MAX	(uint32) UINT_MAX

1	ANSI-C does not allow for use of the sizeof operator in preprocessor statements, which is why we use these _ADDRESS_SIZE macros. These macros are used for Memory Section Management.

WSTCompiler.c

WSTCompiler_Init()

This function calls init_mempool() or xinit_mempool() using a constant INIT_MEMPOOL.

WSTCompilerTypes.h

This file may be part of a Board Support Package installation, and its types may be visible inside a Rhapsody project.

This file defines the following types:

sint8	signed char
uint8	unsigned char
sint16	signed short
uint16	unsigned short
sint32	signed int
uint32	unsigned int
myboolean (see note below)	int
char_t	char
int_t	int
struct_t	unsigned int

Note

The type myboolean is used instead of boolean. This has to do with the fact that in Microsoft and Cygwin environments, the type boolean is already known. The file WSTCompilerTypes.h may be overwritten by Rhapsody generated one for example when using own defined data types in Rhapsody models. A generated WSTCompilerTypes.h may not define the type boolean and to be compatible we define myboolean in the Compiler Bridge file as well as the example Rhapsody project WSTCompilerTypes.
