A good // example would be a configuration option to control the size // of the circular trace buffer. // // On the host side these things are handled by autoconf, and in // particular the configure.in script will offer command-line // arguments allowing the relevant options to be controlled. // The relevant information will end up in <cyg/pkgconf/hostinfra.h> # include <pkgconf/hostinfra.h> // Some options should always be enabled in this header file. #define CYGDBG_INFRA_DIAG_PRINTF_USE_VARARG #define CYGDBG_INFRA_DEBUG_ASSERT_MESSAGE #define CYGDBG_INFRA_DEBUG_TRACE_MESSAGE // Other options should be decided on a package by package basis, // e.g. whether or not assertions are used. On the host side it is // not appropriate to control these globally, instead the infrastructure // always provides the necessary functionality and it is up to the // other parts of the system to decide whether or not the facilities // get used. // A third set of options deal with the environment, e.g. the sizes // of various data types. autoconf macros take care of most of the // work, but some translation is needed into eCos-style names to // avoid namespace pollution. // Process the definitions of SIZEOF_INT_P and SIZEOF_LONG to work // out a sensible data type for CYG_ADDRESS and CYG_ADDRWORD. #if (!defined(SIZEOF_INT_P) || !defined(SIZEOF_LONG)) # error "Configure problem: data type sizes not set" #endif #if (SIZEOF_INT_P == 4) // The default, nothing needs to be done #elif (SIZEOF_INT_P == 8) # define cyg_haladdress cyg_halint64 #else # error "Only 32 and 64 bit pointers are supported" #endif #if ((SIZEOF_INT_P == 4) && (SIZEOF_LONG == 4)) // The default, nothing needs to be done #elif ((SIZEOF_INT_P <= 8) && (SIZEOF_LONG <= 8)) // cyg_halint64 will have been defined appropriately. # define cyg_haladdrword cyg_halint64 #else # error "Only 32 and 64 bit machine word sizes are supported" #endif // Any symbols defined in <pkgconf/hostconf.h> which have been processed // here should no longer be of any interest, and in the interests of // reducing name space pollution they get undef'ed here. // In addition there are two #define's in the config.h header file // which are always present and which have names that are rather too // generic.
