    nikodemus authored
     * TRULY-THE interacts badly with *CHECK-CONSISTENCY*.

     * Make REPLACE *CHECK-CONSISTENCY* happy: the transforms used to have
       return type (VALUES NULL &OPTIONAL), whereas the out-of-line
       definitions had return type (VALUES &OPTIONAL).

    1.0.14.39: make GENCGC gencgc_zero_check=1 proof again

    nikodemus authored
     * 0.9.8.19 moved zeroing from GC time to allocation time, but after
       the point where the check was done -- thus causing the check to
       fail immediately if it was turned on. This commit moves the check
       after the zeroing, so we're good again.
    
       ...which also means that gencgc_zero_check=1 is not very
       interesting anymore, since the zeroing happens in the immediate
       vicinity of the check.

    …86/Linux
    
     * Nothing serious seemed to be going on, though, but since C has nasty
       signed vs unsigned comparison semantics, it is better to be clear
       about what is going on.

    1.0.14.36: faster PROPAGATE-FROM-SETS

    nikodemus authored
     20-25% improvement for the test-case in bug 188.
    
     * New slot in LAMBDA-VAR: LAST-INITIAL-TYPE, which holds the last
       initial-type for that variable seen by PROPAGATE-FROM-SETS.
    
     * Be lazy, and don't PROPAGATE-TO-REFS unless something of
       interest has happened, to wit:
    
        -- One of the CSET nodes has a new, more specific type.
    
        -- INITIAL-TYPE has become more specific.
    
       This also allows us elide TYPE-UNION computation in the
       uninteresting cases.
    
     * Requires having NODE-REOPTIMIZE set when IR1-OPTIMIZE-SET
       is called.

    1.0.14.35: lift MAKE-SINGLE-VALUE-TYPE calls from loops

    nikodemus authored
     * Multiple places can use the same type, no need to cons
       a new one each time through the loop.

    1.0.14.34: slightly less and slightly faster constraint propagation

    nikodemus authored
     * For negated EQL constaints, don't cons up multiple MEMBER-TYPE
       instances during a single pass through CONSTRAIN-REF-TYPE:
       accumulate a single XSET, and turn it into a MEMBER-TYPE only at
       the end.
    
     * Don't construct (NOT (MEMBER ...TON-OF-SYMBOLS...)) types at all,
       unless SPEED > COMPILATION speed. Knowing that a variable is not
       in a set of symbols is seldom useful, and compiling large CASE
       statements with symbols as keys can end up spending huge amounts
       of time just building these sets.
    
     * Adjust FD-STREAMS to use an ECASE in the single place in SBCL where
       without the aforementioned constraint propagation the compiler is
       not able to determine sufficiently constrain the result type.  (Not
       needed since the build has SPEED > COMPILATION-SPEED, but keeps
       things non-brittle.)

    1.0.14.33: Resurrexit Alpha

    csrhodes authored
    	Sort out accumulated bitrot on the Alpha:
    	* xrefs slot for simple_fun: a couple of places in alpha-assem.S
    	* arch_skip_instruction(): compilers more careful about lvalues;
    	* arch_handle_single_step_trap(): implement it.  (Untested)
    	* ld-script.alpha-linux: update for newer systems.
    
    	Works For Me.  Other systems may vary.

    1.0.14.32: fix bug 407

    nikodemus authored
     * %SINGLE-FLOAT and %DOUBLE-FLOAT should not be flushable.
    
     * BUGS entry remains: should (COERCE (EXPT 2 1024) 'SINGLE-FLOAT)
       really signal a TYPE-ERROR?

    1.0.14.31: better ANSI-STREAM-FILE-POSITION

    nikodemus authored
     * Instead of searching for the external-format object to obtain
       the character-width function, store the function (or its result
       for fixed-width external formats) directly into the FD-STREAM
       object. Non-FD-STREAM ANSI-STREAMS use the old strategy.

    1.0.14.30: don't construct obsolete instances

    csrhodes authored
    	The CTOR make-instance optimization machinery closes over the
    	class wrapper of the class in question; however, there are
    	code paths that cause wrappers to be invalidated without causing
    	all constructors to be recomputed: for instance, the
    	redefinition of a superclass, or calling
    	MAKE-INSTANCES-OBSOLETE.  This would mean that the CTORs would
    	create obsolete instances, which would instantly trap, showing
    	up as slowness in CLOS-heavy code.
    
    	Problem and fix largely identified by Andy Hefner in
    	<http://paste.lisp.org/display/55689>.

    1.0.14.28: small FGEN improvements

    nikodemus authored
     * Use a DEFSTRUCT instead of a vector for clarity. Also eliminate the
       unused mystery slot.
    
     * Inline code of GET-NEW-FUN-GENERATOR-INTERNAL in
       GET-NEW-FUN-GENERATOR.
    
     * Store in a hash-table for O(1) goodness instead of a list.
    
     * ENSURE-FGEN instead of MAKE-FGEN + STORE-FGEN.
    
     * When lifting constants out of code in FGEN construction, leave
       constant lists in place: several of the functions we generate FGENs
       for have ETYPECASE forms, which will otherwise cause us to close
       over the :EXPECTED-TYPE and :POSSIBILITIES arguments to ERROR for
       no good reason.

    1.0.14.27: rename MAKE-FIXNUM to POINTER-HASH

    nikodemus authored
     * Use VOP translation instead of %PRIMITIVE.
    
     * On x86 and x86-64 improve the pointer-hash slightly: use the whole
       address, but none of the tag bits in the hash.
    
     * Fix type in INDEX-FOR-HASHING: the first argument is a HASH, not an
       INDEX. Given the better quality of low bits on x86oids (and
       hopefully soon on others as well), adjust the mixing a bit.

    1.0.14.26: tweak COND slightly

    nikodemus authored
     * Don't expand into a final (COND), but directly to NIL (easier to
       read macroexpansion.)
    
     * Check for the common case of final T, so that the last clause can be
       unconditional instead of generating redundant IF.
  2. @nikodemus

    1.0.14.25: trivial WHEN & UNLESS change

    nikodemus authored
     * Implement directly on top of IF & PROGN instead of COND: clearer
       macroexpansion, and slightly less work to compile to boot.

    1.0.14.22: more backtrace verbosity, for a change

    nikodemus authored
     * Revert part of the *SHOW-ENTRY-POINT-DETAILS* functionality: always
       return the DEBUG-FUN-KIND from FRAME-CALL, so that instead of the
       rather confusing
    
        (FOO MY-ARGUMENT)
        (FOO MY-ARGUMENT)
    
       a slightly mysterious but hopefully less confusing
    
        (FOO MY-ARGUMENT)
        (FOO MY-ARGUMENT) [:EXTERNAL]
    
       appears in backtraces where the XEP hasn't been tail-merged.

     * Add :SYNCHRONIZED to thr DEFKNOWN.
    
     * Also fix a bit of totally broken indentation in the
       hash-table code.
    
     * Cautionary comment about a potential type-error in parallel code.
    
     * More threaded hash-table tests.

    1.0.14.17: treat (NAMED-LAMBDA NIL ...) like (LAMBDA ...)

    nikodemus authored
     * Getting NIL as the source-name of a functional is pretty bogus, and
       getting it as the debug-name messes with our careful debug-name
       sanity checks. So don't do it then.

    1.0.14.13: Rewrite non-standard LOOP syntax

    jsnell authored
            * Using XCL as the host compiler did not work due to a FOR/WHILE/FOR
              sequence (which is not defined in the spec, though supported by
              most implementations). Reported by Peter Graves.

    1.0.14.10: friendly CHECK-TYPE error message for quoted type-specifiers

    nikodemus authored
     * (QUOTE ...) is never a valid type-specifier.
    
     * When printing the macro-form responsible for an error, increase
       *PRINT-LEVEL* from 1 to 3, for a slightly better compiler-log
       reading experience.
