- acos, atan, ... ANSI C names).
-
- - Release - 0.91 - Wednesday July 24 1996
- * Incremental C compiling mode implemented (see option -c_code
- in man/compile.hlp).
- * Added command `clean' (see man/clean.hlp).
- * Added class FILE_TOOLS.
- * No more empty C struct in generated C code (to avoid problems
- with Microsoft Windows C compiler).
- * Fixed one more bug with conformance rule VNCG.
-
- - Release - 0.90 - Friday August 23 1996
- * Added random number generator library (SmallEiffel/lib_rand).
- * Added checking of assertions for external "CSE" features.
- * Anchoring on expanded types are now allowed.
- * Multiple level of anchoring definition allowed.
- * Fixed a bug in STRING.from_external.
- * Fixed a bug with mixed rename/redefine.
- * Inheritance loop detection.
- * Anchoring loop detection.
- * Fixed a bug with renaming infix/prefix.
- * Command `clean' also use the make suffix.
- * Added ELKS95 `sign' in INTEGER/REAL/DOUBLE.
- * Feature `make' is the default root feature name for `compile'.
- * Optimized ARRAY.add_last and STRING.extend.
- * Changed STRING.out (no more enclosing %" printed).
- * Remove warning gcc messages for 64 bits machine (alpha/DECK).
- * Added option -no_split for a better finalization (see
- compile_to_c.hlp).
-
- - Release - 0.89 - Sunday September 15 1996
- * Calling Eiffel from C is now implemented (see cecil.hlp).
- * Object creation uses C `calloc' instead 'malloc'+`memset'.
- * Object creation is inlined.
- * ARRAY/FIXED_ARRAY `put' and `item' are now inlined (-boost only).
- * Added feature `capacity' and `resize' in FIXED_ARRAY.
- * Added some classes in std_lib: LINK2_LIST (two way linked
- list), COLLECTION2 (deferred), ARRAYED_COLLECTION (deferred),
- LINKED_COLLECTION (deferred) and FIXED_ARRAY2 in std_lib.
- * More user's routines are inlined (-boost only).
-
- - Release - 0.88 - Wednesday October 30 1996
- * Fixed bugs dealing with inherit/rename/select.
- * Added warning for missing colon in actual arguments list.
- * Warning : INSTALL procedure has changed and you have to set
- manually the default loading path (see misc/INSTALL for details).
- * Added some VMS customisation.
- * Fixed bugs when printing run-time stack.
- * Warning added for missing colon in actual parameter list.
- * Added `flush' in STD_FILE_WRITE.
- * No more left hand side cast in C code.
-
- - Release - 0.87 - Tuesday January 7 1997
- * Added a new flag "-trace" to ease debug (see compile_to_c.hlp).
- * More inlining at Eiffel level (-boost mode only).
- * Class BIT_N completely revisited. It may be as fast as C.
- * Added class C_ARRAY[E] to deal directly with C arrays at Eiffel
- level. Thus there are no more external "CSE" or c_inline_c in
- classes STRING/ARRAY/FIXED_ARRAY (only full Eiffel).
- Eiffel code is nice and STRING/ARRAY/FIXED_ARRAY may run faster.
- * Fixed a bug in STD_FILE_READ.read_double.
- * Ordering of C output to increase gcc inlining.
- * According to compile_to_c.hlp, -debug_check now works (debug
- instructions are no longuer generated in mode -all_check).
- * Unused local variables removed at Eiffel level (warning added
- for -debug_check mode only).
- * Default class ANY now inherit PLATFORM (as in ETL).
- * Fixed a bug in floating-point constants.
- * Added directory `sys' to customize default C compiler, default
- C linker and default loading path.
- * Fixed some bugs with outside expanded types.
- * Fixed a bug with rename/select.
- * Redefinition of once routine is now allowed.
- * Feature GENERAL.conforms_to is now implemented.
- * Rule VFFD.7 is now enforced.
- * Feature `force' implemented for all COLLECTION.
- * Added conversions features CHARACTER.to_bit, INTEGER.to_bit,
- BIT_N.to_character and BIT_N.to_integer.
-
- - Release - 0.86 - Sunday April 13 1997
- * All reported bugs at this time are fixed.
- * Added flag -verbose to commands `compile', `compile_to_c' and
- `clean'. When this new flag is not present, commands now works silently
- unless some error (or warning) occurs.
- * Features BOOLEAN.infix"or" and BOOLEAN.infix"and" are now written in
- pure Eiffel. As a consequence, it is very important for the SmallEiffel
- programmer to make the distinction between BOOLEAN.infix"and then" and
- BOOLEAN.infix"and" (respectively for BOOLEAN.infix"or else" and
- BOOLEAN.infix"or"). When LHS argument produce no side effects, the
- semi-strict operator (BOOLEAN.infix"and" and BOOLEAN.infix"or") may run
- faster.
- * Fixed REAL.sin (was calling sqrt :-).
- * Fixed a bug in INTEGER.append_in (you can now print Minimum_integer).
- * Added feature COMPARABLE.in_range.
- * Result type of REAL.infix "^" is now DOUBLE for ELKS compatibility.
- * Feature `remove' is now implemented in all subclasses of COLLECTION
- (i.e. ARRAY, FIXED_ARRAY, LINK_LIST and LINK2_LIST).
- * Added feature `add' for all subclasses of COLLECTION.
- * Conversion DOUBLE/STRING : ANSI C `sscanf' and `sprintf' is now used
- to avoid loss of precision.
- * Added some more class invariant code generation when compiling in
- -invariant_check mode. Class invariant is now check before exit of a
- routine.
- * Added feature `file_tools' in class GENERAL to ease access to class
- FILE_TOOLS.
- * Changed printing format for basic *_REF classes. For example,
- instruction `print(1);' now print 1.
- * DOUBLE.truncated_to_integer is now ELKS compatible (added DOUBLE.rounded
- to replace the old DOUBLE.truncated_to_integer). Same change in class
- REAL.
-
- --- WORK IN PROGRESS (current priority list) --- :
- * Command `compile_to_jvm' to produce Java Byte Code from Eiffel.
- * Command `short' to produce short and flat-short.
- * Command `check_up' to check system validity rules.
