changes in sbcl-0.7.7 relative to sbcl-0.7.6:
* An alpha-quality port to the parisc architecture running Linux,
- based on the old CMUCL backend has been made. This, even more so
+ based on the old CMUCL backend, has been made. This, even more so
than the other backends, should be considered still a work in
progress; known problems include that the Linux kernel in 64-bit
mode does not propagate the correct sigcontext structure to
SB-KERNEL:CONTROL-STACK-EXHAUSTED condition (subclass of
STORAGE-CONDITION) is signalled, so stack exhaustion can no longer
be caught using IGNORE-ERRORS.
+ * Bugs 65, 70, and 109 fixed: The compiler now preserves invariants
+ correctly when transforming recursive LABELS functions to LETs.
+ (thanks to Alexey Dejneka)
* Bug 48a./b. fixed: SYMBOL-MACROLET now refuses to bind symbols
that are names of constants or global variables.
* Bug fix: DEFINE-ALIEN-ROUTINE now declaims the correct FTYPE for
* The fasl file version number has changed again. (because of the
bug fix involving the names of PCL MAKE-INSTANCE functions)
+changes in sbcl-0.7.8 relative to sbcl-0.7.7:
+ * A beta-quality port to the mips architecture running Linux,
+ based on the old CMUCL backend, has been made. It has been tested
+ on a big-endian kernel, and works sufficiently well to be able to
+ rebuild itself; it has not been tested in little-endian mode.
+ * fixed an inconsistency between gencgc.c and purify.c which made
+ dumping/loading .core files unreliable
+ * fixed bug 120a: The compiler now deals correctly with IFs where
+ the consequent is the same as the alternative, instead of
+ misderiving the return type. (thanks to Alexey Dejneka)
+ * fixed bug 113: Logical pathnames are now dumpable (the logical
+ host is resolved at load-time, throwing an error if it is not
+ found).
+ * fixed bug 174: FORMAT's error message is slightly clearer when a
+ non-printing character is used in a format directive.
+ * fixed several bugs in compiler checking of type declarations, i.e.
+ violations of the Python "declarations are assertions" principle
+ (thanks to Alexey Dejneka)
+ * fixed several bugs in PCL's error checking (thanks to Gerd
+ Moellmann)
+ * fixed bug: printing of FILE-ERROR (thanks to Antonio
+ Martinez-Shotton)
+ * fixed bug in compilation of functions as first class values
+ (thanks to Antonio Martinez-Shotton)
+ * The compiler's handling TYPE-ERRORs which it can prove will
+ inevitably happen at runtime has been cleaned up and corrected
+ in several ways. (thanks to Alexey Dejneka)
+ * improved argument type checking for various basic arithmetic
+ operations (MAX, +, LOGXOR, etc.) which have had so much TLC
+ lavished on them in the past that they can be compiled in many
+ ways in different special cases
+ * fixed bug 181: compiler checks validity of user supplied type
+ specifiers
+ * cleaned up code flushing in optimization: Function calls which
+ should signal errors for safety purposes (e.g. which ANSI says
+ should signal errors when their arguments are of incorrect type)
+ are no longer optimized away.
+ * added new extension: SB-DEBUG:BACKTRACE-AS-LIST
+ * incremented fasl file version number, because changes in the
+ implementation of sequence functions like COERCE caused
+ internal utility functions like COERCE-TO-SIMPLE-VECTOR (used
+ in old inline expansions) to become undefined. (Actually these
+ changes were later undone, so we might very well be binary
+ compatible with 0.7.7 after all, but leaving the version number
+ incremented seemed like the simplest and most conservative
+ thing to do.)
+
+changes in sbcl-0.7.9 relative to sbcl-0.7.8:
+ * minor incompatible change: The runtime (the Unix executable named
+ "sbcl") is now much pickier about the .core files it will load.
+ Essentially it now requires .core files to descend from the same
+ build (not just the same sources or LISP-IMPLEMENTATION-VERSION)
+ as the runtime does. (The intent is to prevent the crashes which
+ can occur, and which can even be reported as mysterious failures,
+ when people patch the sources or change the build parameters
+ without changing LISP-IMPLEMENTATION-VERSION, then mix and match
+ sbcl and .core files.)
+ * fixed bug: VALUES-LIST is no longer optimized away.
+ * fixed bug 142: The FFI conversion of C string values to Lisp
+ string values no longer conses excessively. (thanks to Nathan
+ Froyd porting Raymond Toy's fix to CMU CL)
+ * improved MOP conformance in PCL (thanks to Nathan Froyd porting
+ Gerd Moellman's work in CMU CL)
+ * fixed bug 202: The compiler no longer fails on functions whose
+ derived types contradict their declared type.
+ * DEFMACRO is implemented via EVAL-WHEN instead of IR1 translation,
+ so it can be non-toplevel.
+ * The fasl file version number has changed (because of the new
+ implementation of DEFMACRO).
+ * fixed bugs 46h and 46i: TWO-WAY- and CONCATENATED-STREAM creation
+ functions now check the types of their inputs as required by ANSI.
+ * fixed bug 48c: SYMBOL-MACROLET signals PROGRAM-ERROR when an
+ introduced symbol is DECLAREd to be SPECIAL.
+ * fixed reading of (COMPLEX DOUBLE-FLOAT) literals from fasl files
+ * fixed bug: :COUNT argument to sequence functions may be negative
+ * fixed bug: body of DO-SYMBOLS may contain declarations
+
planned incompatible changes in 0.7.x:
* When the profiling interface settles down, maybe in 0.7.x, maybe
later, it might impact TRACE. They both encapsulate functions, and
