//======================================================================

// The purpose of this header file is to replicate appropriate

// functionality from the target-side header file <pkgconf/infra.h>.

// This header file is intended to contain configuration options

// related to the implementation of the infrastructure, as opposed

// to how that infrastructure gets used by other packages. 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"

// 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. These get removed here as well. The version is worth

// preserving under a different name.
