/**
* \file
* \brief Platform feature descriptions and dependency checks
*
* This file explains the purpose of all of the HAVE_* features
* and provides logical checks for features that depend on other features.
*
* A platform defines the features it wants in src/platform/<plat>/pmfeatures.py
* A tool generates C HAVE_* definitions in pmfeatures.h from pmfeatures.py.
*
*
* HAVE_PRINT
* ----------
*
* When defined, bytecodes PRINT_ITEM and PRINT_NEWLINE are supported. Along
* with these, helper routines in the object type are compiled in that allow
* printing of the object.
* REQUIRES stdio.h to have snprintf()
*
*
* HAVE_GC
* -------
*
* When defined, the code to perform mark-sweep garbage collection is included
* in the build and automatic GC is enabled. When undefined the allocator
* will distribute memory until none is left, after which a memory exception
* will occur.
*
*
* HAVE_FLOAT
* ----------
*
* When defined, the code to support floating point objects is included
* in the build.
* Issue #148 Create configurable float datatype
*
*
* HAVE_DEL
* --------
*
* When defined, the code to support the keyword del is included in the build.
* This involves the bytecodes: DELETE_SUBSCR, DELETE_NAME, DELETE_ATTR,
* DELETE_GLOBAL and DELETE_FAST.
*
*
* HAVE_IMPORTS
* ------------
*
* When defined, the code to support the IMPORT_FROM and IMPORT_STAR styles
* is included in the build.
*
*
* HAVE_DEFAULTARGS
* ----------------
*
* When defined, the code to support default arguments to functions is included
* in the build.
* Issue #157 Support default args
*
*
* HAVE_REPLICATION
* ----------------
*
* When defined, the code to support sequence (list, tuple, string) replcation
* is included in the build.
* This feature is required by the builtin function __bi.map().
* #160 Add support for string and tuple replication
*
*
* HAVE_CLASSES
* ------------
*
* When defined, the code to support classes, instances, methods, etc.
* is included in the build.
* Issue #202 Implement classes in the vm
*
*
* HAVE_ASSERT
* -----------
*
* When defined, the code to support the assert statement is included
* in the build.
*
*
* HAVE_GENERATORS
* ---------------
*
* When defined, the code to support the yield keyword's use for
* generator-iterators is included in the build.
* Issue #207 Add support for the yield keyword
*
*
* HAVE_BACKTICK
* -------------
*
* When defined, the code to support the backtick operation (`x`) is included
* in the build.
* REQUIRES stdio.h to have snprintf()
* Issue #244 Add support for the backtick operation (UNARY_CONVERT)
*
*
* HAVE_STRING_FORMAT
* ------------------
*
* When defined, the code to perform string formatting using the binary modulo
* operator is included in the build.
* REQUIRES stdio.h to have snprintf()
* Issue #205 Add support for string format operation
*
*
* HAVE_CLOSURES
* -------------
*
* When defined, the code to support function closures is included in the
* build.
* Issue #256 Add support for closures
*
*
* HAVE_BYTEARRAY
* --------------
*
* When defined, the code to support the bytearray type is included in the
* build. NOTE: If this is defined, the bytearray class in src/lib/__bi.py
* must also be uncommented.
* Issue #289 Create bytearray datatype
*
*
* HAVE_DEBUG_INFO
* ---------------
*
* When defined, the code to support debug information in exception reports
* is included in the build.
* Issue #103 Add debug info to exception reports
