Raymond Toy pushed to branch issue-294-xoroshiro-lisp-assem-routine at cmucl / cmucl Commits: 1ec83248 by Raymond Toy at 2024-04-01T17:28:35-07:00 Change the registers used for state, r1, and r0 These registers show that in `xoroshiro-gen`, all the registers are in the right place so we don't need to do any additional moves. This is a nice micro-optimization. - - - - - 1 changed file: - src/assembly/x86/arith.lisp Changes: ===================================== src/assembly/x86/arith.lisp ===================================== @@ -447,8 +447,8 @@ (:policy :fast-safe) (:arg-types simple-array-double-float) (:result-types unsigned-num unsigned-num)) - ((:arg state descriptor-reg eax-offset) - (:res r1 unsigned-reg edx-offset) + ((:arg state descriptor-reg edx-offset) + (:res r1 unsigned-reg ecx-offset) (:res r0 unsigned-reg ebx-offset) (:temp s0 double-reg xmm0-offset) (:temp s1 double-reg xmm1-offset) View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/-/commit/1ec832483118f863620fd90… -- View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/-/commit/1ec832483118f863620fd90… You're receiving this email because of your account on gitlab.common-lisp.net.
