Raymond Toy pushed to branch master at cmucl / cmucl Commits: a5805ca0 by Raymond Toy at 2016-01-06T21:00:07Z If -dynamic-space-size is 0, use the max heap. If the user specifies -dynamic-space-size 0, then use the platform-specific maximum heap size. Update the docstring for the switch too. - - - - - 2 changed files: - src/code/commandline.lisp - src/lisp/lisp.c Changes: ===================================== src/code/commandline.lisp ===================================== --- a/src/code/commandline.lisp +++ b/src/code/commandline.lisp @@ -283,8 +283,9 @@ (defswitch "dynamic-space-size" nil "Specifies the number of megabytes that should be allocated to the - heap.
