[Git][cmucl/cmucl][master] Fix compiler warning about else
by Raymond Toy 31 Aug '17

31 Aug '17

Raymond Toy pushed to branch master at cmucl / cmucl Commits: 3b4f3977 by Raymond Toy at 2017-08-30T21:21:56-07:00 Fix compiler warning about else Add braces around the else clause that's indented as if it were part of the else clause. Inspection of the algorithm indicates that this is probably the intended code and in this case doesn't change what gets executed because the following statements would have been anyway. Also verified a few random values that `(asin x)` and `(asin (float x 1w0))` produce the same values. Only need to test 2^-27 <= x < 0.5. - - - - - 1 changed file: - src/lisp/e_asin.c Changes: ===================================== src/lisp/e_asin.c ===================================== --- a/src/lisp/e_asin.c +++ b/src/lisp/e_asin.c @@ -94,12 +94,13 @@ qS4 = 7.70381505559019352791e-02; /* 0x3FB3B8C5, 0xB12E9282 */ } return x; - } else + } else { t = x*x; p = t*(pS0+t*(pS1+t*(pS2+t*(pS3+t*(pS4+t*pS5))))); q = one+t*(qS1+t*(qS2+t*(qS3+t*qS4))); w = p/q; return x+x*w; + } } /* 1> |x|>= 0.5 */ w = one-fabs(x); View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/commit/3b4f3977d3260cb81c41c1d15… --- View it on GitLab: https://gitlab.common-lisp.net/cmucl/cmucl/commit/3b4f3977d3260cb81c41c1d15… You're receiving this email because of your account on gitlab.common-lisp.net.

[Git][cmucl/cmucl][master] 4 commits: Fix #40: Move start of heap space higher
by Raymond Toy 29 Aug '17

29 Aug '17

Raymond Toy pushed to branch master at cmucl / cmucl Commits: c40b7a6b by Raymond Toy at 2017-08-29T10:38:13-07:00 Fix #40: Move start of heap space higher This is a workaround for issue #40. By moving the start of the heap to a higher address, we can still run on older systems (albeit with reduced max heap size), and run on newer systesm where the C code is now mapped at or overlapping the (old) heap start. Arbitrarily choose 0x60000000 as a compromise. This also requires moving the foreign linkage start to a different address because the old address overlaps the new C area. Ideally, we could fix this if we could map the heap wherever the OS wants to put it, but we're not there yet. Use boot-2017-04.lisp to bootstrap this change from the 2017-04 snapshot. - - - - - 48f8ebb9 by Raymond Toy at 2017-08-29T10:54:21-07:00 Add handler-bind to auto restart Changing defconstant's signal an error.
