2/24/92 to 3/2/92
Code:
Added some dimension type checking to parsing of alien array types.
Fixed a bug where the size of single-floats and double-floats wasn't know
by the new aliens stuff.
Really make sure compute-time-overhead-ax has function type info in
profile.
Reworked the SETQ branch of EVAL to pass more cases (like setting alien
vars or constants) off to the real interpreter.
Fixed FMAKUNBOUND to return the symbol instead of T.
Moved OS-INIT into mumble-os.lisp, so that different OSes can do different
things for initialization.
SET now protects against setting T, NIL, and keywords. (SETF
SYMBOL-FUNCTION) now expands into FSET, which protects against defining
NIL. %SET-SYMBOL-PACKAGE is a new function that sets the symbol package.
%SP-SET-PLIST has been renamed %SET-SYMBOL-PLIST.
Fixed the ``mumble doesn't start with a search-list'' error message.
Fixed the MIPS disassembler OR control to look at the RT field instead of
the RD field.
Compiler:
Weakened component kind type assertion in JOIN-COMPONENTS.
Changed the %DEFCONSTANT transform to protect against trying to change T,
NIL, or keywords.
Changed LET* and &AUX to allow duplicate variable names.
Re-wrote the SAP-REF-mumble VOPs for better immediate support.
CLX:
Don't try to set char-bits for CMU, because we don't have any.
C runtime support:
Instead of using os_zero to zero the control stack after a GC, fill it with
zeros ourselves.
Whenever we allocate a chunk of memory, set the protections to include
VM_PROT_EXECUTE so that we can execute code on it. This is so we can run
under MACH 3.0.
