[Git][cmucl/cmucl][rtoy-mmap-anon-control-and-binding-stacks] 10 commits: Rename arguments to RENAME-PACKAGE and update docstring

Raymond Toy pushed to branch rtoy-mmap-anon-control-and-binding-stacks at cmucl / cmucl Commits: f7e92b73 by Raymond Toy at 2015-11-10T21:39:15Z Rename arguments to RENAME-PACKAGE and update docstring Can't ever remember the order of arguments for RENAME-PACKAGE so just rename the variables to make it clearer. And update the docstring to be a little more verbose. - - - - - 5d3a63fa by Raymond Toy at 2015-11-28T16:43:54Z Support constant shifts for bignum digits. This gets rid of the load of the shift amount to ecx, saving one instruction and reducing pressure on the ecx register. - - - - - a613a908 by Raymond Toy at 2015-11-28T16:45:41Z Regenerated (due to docstring change for rename-package). - - - - - 1b8b84be by Raymond Toy at 2015-12-01T21:41:49Z Handle large (fixed) shift amounts for the digit shifters. Make the vops handle the case when the known constant shift amount is so large that the result is a known value. Plus, the instructions have a fixed immediate argument size and the amount is taken mod 32 which would produce the wrong result if the actual shift amount were used. - - - - - 5406768c by Raymond Toy at 2015-12-02T20:07:43Z Linux needs unix-setitimer Cut and paste error from unix-glibc2.lisp copied unix-getitimer instead of unix-setitimer which is needed by SAVE-LISP. - - - - - be500bc5 by Raymond Toy at 2015-12-05T16:10:46Z Regenerated. - - - - - 1d64f63b by Raymond Toy at 2015-12-05T17:01:22Z Update from logs. - - - - - 7a1457da by Raymond Toy at 2015-12-11T19:25:30Z New implementation of the digit shifters. Define new vops for the digit shifters that take a constant (unsigned-byte 5) value. The previous version, while correct, still causes the ecx register to spill because it was a temporary. This doens't cause the compiler to spill ecx unnecessarily anymore. - - - - - c91ff829 by Raymond Toy at 2015-12-12T08:51:40Z Update lisp-unit. - - - - - 275011da by Raymond Toy at 2015-12-13T21:35:03Z Merge branch 'master' into rtoy-mmap-anon-control-and-binding-stacks - - - - - 8 changed files: - src/code/package.lisp - src/code/unix.lisp - src/compiler/x86/arith.lisp - src/contrib/lisp-unit/internal-test/example-tests.lisp - src/contrib/lisp-unit/lisp-unit.lisp - src/general-info/release-21b.txt - src/i18n/locale/cmucl-unix.pot - src/i18n/locale/cmucl.pot Changes: ===================================== src/code/package.lisp ===================================== --- a/src/code/package.lisp +++ b/src/code/package.lisp @@ -1204,23 +1204,25 @@ ;;; Change the name if we can, blast any old nicknames and then ;;; add in any new ones. ;;; -(defun rename-package (package name &optional (nicknames ())) - "Changes the name and nicknames for a package." +(defun rename-package (package new-name &optional (new-nicknames ())) + "Replaces the name and nicknames of Package.

[Git][cmucl/cmucl][master] New implementation of the digit shifters.
by Raymond Toy 12 Dec '15

12 Dec '15

Raymond Toy pushed to branch master at cmucl / cmucl Commits: 7a1457da by Raymond Toy at 2015-12-11T19:25:30Z New implementation of the digit shifters. Define new vops for the digit shifters that take a constant (unsigned-byte 5) value. The previous version, while correct, still causes the ecx register to spill because it was a temporary. This doens't cause the compiler to spill ecx unnecessarily anymore. - - - - - 1 changed file: - src/compiler/x86/arith.lisp Changes: ===================================== src/compiler/x86/arith.lisp ===================================== --- a/src/compiler/x86/arith.lisp +++ b/src/compiler/x86/arith.lisp @@ -1445,7 +1445,7 @@ (:translate bignum::%ashr) (:policy :fast-safe) (:args (digit :scs (unsigned-reg unsigned-stack) :target result) - (count :scs (unsigned-reg immediate))) + (count :scs (unsigned-reg))) (:arg-types unsigned-num positive-fixnum) (:temporary (:sc unsigned-reg :offset ecx-offset :from (:argument 1)) ecx) (:results (result :scs (unsigned-reg) :from (:argument 0) @@ -1454,53 +1454,52 @@ (:result-types unsigned-num) (:generator 2 (move result digit) - (sc-case count - (unsigned-reg - (move ecx count) - (inst sar result :cl)) - (immediate - (let ((amount (tn-value count))) - ;; If the amount is greater than 31, it's the same as - ;; shifting by 31, leaving just the sign bit. - (inst sar result (if (>= amount vm:word-bits) - (1- vm:word-bits) - amount))))))) + (move ecx count) + (inst sar result :cl))) + +(define-vop (digit-ashr-c) + (:translate bignum::%ashr) + (:policy :fast-safe) + (:args (digit :scs (unsigned-reg unsigned-stack) :target result)) + (:info count) + (:arg-types unsigned-num (:constant (unsigned-byte #.(1- (integer-length vm:word-bits))))) + (:results (result :scs (unsigned-reg) :from (:argument 0) + :load-if (not (and (sc-is result unsigned-stack) + (location= digit result))))) + (:result-types unsigned-num) + (:generator 1 + (move result digit) + ;; If the count is greater than 31, it's the same as + ;; shifting by 31, leaving just the sign bit. + (inst sar result count))) (define-vop (digit-lshr digit-ashr) (:translate bignum::%digit-logical-shift-right) (:generator 2 - (sc-case count - (unsigned-reg - (move result digit) - (move ecx count) - (inst shr result :cl)) - (immediate - (let ((amount (tn-value count))) - ;; If the amount is greater than 31, the result is 0 because - ;; all the bits get shifted right and out. - (cond ((>= amount vm:word-bits) - (inst mov result 0)) - (t - (move result digit) - (inst shr result count)))))))) + (move result digit) + (move ecx count) + (inst shr result :cl))) + +(define-vop (digit-lshr-c digit-ashr-c) + (:translate bignum::%digit-logical-shift-right) + (:generator 1 + (move result digit) + (inst shr result count))) (define-vop (digit-ashl digit-ashr) (:translate bignum::%ashl) (:generator 2 - (sc-case count - (unsigned-reg - (move result digit) - (move ecx count) - (inst shl result :cl)) - (immediate - (let ((amount (tn-value count))) - ;; If the amount is greater than 31, the result is 0 because - ;; all the bits get shifted left and out. - (cond ((>= amount vm:word-bits) - (inst mov result 0)) - (t - (move result digit) - (inst shl result amount)))))))) + (move result digit) + (move ecx count) + (inst shl result :cl))) + +(define-vop (digit-ashl-c digit-ashr-c) + (:translate bignum::%ashl) + (:generator 1 + (move result digit) + (inst shl result count))) + + ;;;; Static functions.
