[Git][cmucl/cmucl][master] 2 commits: Complex array accessors are not foldable
by Raymond Toy 19 Feb '18

Raymond Toy pushed to branch master at cmucl / cmucl Commits: e9a598e5 by Raymond Toy at 2018-02-19T08:41:07-08:00 Complex array accessors are not foldable Fixes #61 and #62. The `ARRAY-HAS-FILL-POINTER-P` and `ARRAY-DISPLACEMENT` functions are declared inline and the compiler tries to constant-fold these inlined functions operating on simple arrays. Thus don't allow the compiler to constant-fold calls to `%ARRAY-FILL-POINTER-P`. This is normally protected by a call to `ARRAY-HEADER-P`, but when it's inlined, the compiler tries to constant-fold `%ARRAY-FILL-POINTER-P` on an array without such a slot. Likewise `ARRAY-DISPLACEMENT` calls `%ARRAY-DISPLACED-P`, `%ARRAY-DATA-VECTOR`, and `%ARRAY-DISPLACEMENT`, and the calls are protected by `ARRAY-HEADER-P`. So don't constant-fold these either. Maybe we could also make CONSTANT-FOLD-CALL be smarter about this? * src/compiler/generic/objdef.lisp * Remove flushable from these ref-trans methods. * src/general-info/release-21d.md * Update * tests/issues.lisp * Add tests from the bug reports. - - - - - ac4b9fc8 by Raymond Toy at 2018-02-19T16:50:47+00:00 Merge branch 'rtoy-fix-61-62-not-flushable' into 'master' Complex array accessors are not foldable Closes #61 and #62 See merge request cmucl/cmucl!38 - - - - - 3 changed files: - src/compiler/generic/objdef.lisp - src/general-info/release-21d.md - tests/issues.lisp Changes: ===================================== src/compiler/generic/objdef.lisp ===================================== --- a/src/compiler/generic/objdef.lisp +++ b/src/compiler/generic/objdef.lisp @@ -252,29 +252,32 @@ :ref-known (flushable foldable) :set-trans (setf %array-fill-pointer) :set-known (unsafe)) + ;; Don't let these ref-trans to be constant-folded because these + ;; might get called on arrays that don't have these slots.

[Git][cmucl/cmucl][master] 2 commits: Fix #58: Bogus type error in comparison of complex number with `THE` form

Because of the `THE` form, the type of the float was `(member 1d0)`, so the compiler was coercing `#c(1/2 1/2)` to `(complex (double-float 1d0))`, which is wrong. Therefore, coerce the complex to just the type format of the real part, ignoring any bounds. * src/compiler/float-tran.lisp * Coerce to format type, discarding any bounds * src/general-info/release-21d.md * Update notes * tests/issues.lisp * Added test for this - - - - - 771fd903 by Raymond Toy at 2018-02-18T17:11:19+00:00 Merge branch 'rtoy-fix-issue-58' into 'master' Fix #58: Bogus type error in comparison of complex number with `THE` form Closes #58 See merge request cmucl/cmucl!37 - - - - - 3 changed files: - src/compiler/float-tran.lisp - src/general-info/release-21d.md - tests/issues.lisp Changes: ===================================== src/compiler/float-tran.lisp ===================================== --- a/src/compiler/float-tran.lisp +++ b/src/compiler/float-tran.lisp @@ -1903,7 +1903,7 @@ (deftransform upgraded-complex-real-contagion-arg1 ((x y) * * :defun-only t :node node) ;;(format t "upgraded-complex-real-contagion-arg1~%") `(,(continuation-function-name (basic-combination-fun node)) - (coerce x '(complex ,(type-specifier (continuation-type y)))) + (coerce x '(complex ,(numeric-type-format (continuation-type y)))) y)) ;;; (deftransform upgraded-complex-real-contagion-arg2 ((x y) * * :defun-only t :node node) @@ -1912,7 +1912,7 @@ (continuation-type x) (continuation-type y)) `(,(continuation-function-name (basic-combination-fun node)) x - (coerce y '(complex ,(type-specifier (continuation-type x)))))) + (coerce y '(complex ,(numeric-type-format (continuation-type x)))))) (dolist (x '(= + * / -)) ===================================== src/general-info/release-21d.md ===================================== --- a/src/general-info/release-21d.md +++ b/src/general-info/release-21d.md @@ -34,6 +34,7 @@ public domain. * ~~#47~~ Backquate and multiple splices * ~~#59~~ Incorrect type-derivation for `decode-float` * ~~#60~~ The function `C::%UNARY-FROUND` is undefined + * ~~#58~~ Bogus type error in comparison of complex number with `THE` form * Other changes: * Improvements to the PCL implementation of CLOS: * Changes to building procedure: ===================================== tests/issues.lisp ===================================== --- a/tests/issues.lisp +++ b/tests/issues.lisp @@ -515,3 +515,9 @@ (assert-equalp (values 2d0 0d0) (funcall c14 2d0)))) + +(define-test issue.58 + (:tag :issues) + (let ((c9 (compile nil #'(lambda (x) + (= (the (eql 1.0d0) x) #c(1/2 1/2)))))) + (assert-false (funcall c9 1.d0)))) View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/compare/31c6bf9faef2ce24d42d5af0… --- View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/compare/31c6bf9faef2ce24d42d5af0… You're receiving this email because of your account on gitlab.common-lisp.net.
