// Purpose:      Define symbols for use in linker scripts and "generic" asm
// Description:  This file should only use #defines - it should be safe
//               to include from both linker scripts and assembler files
// Usage:        #include <cyg/infra/cyg_type.inc>
//
//

// -------------------------------------------------------------------------
// Label name macros. Some toolsets generate labels with initial
// underscores and others don't. CYG_LABEL_NAME should be used on
// labels in C/C++ code that are defined in assembly code or linker
// scripts. CYG_LABEL_DEFN is for use in assembly code and linker
// scripts where we need to manufacture labels that can be used from
// C/C++.
// These are default implementations that should work for most targets.
// They may be overridden in basetype.h if necessary.

// Provide a default architecture alignment.
// This may be overridden in basetype.h if necessary.
