Raymond Toy pushed to branch rtoy-mmap-anon-control-and-binding-stacks at cmucl / cmucl Commits: 951611cf by Raymond Toy at 2016-05-09T21:02:47-07:00 Add RELOCATABLE_STACK_START to control stack spaces When RELOCATABLE_STACK_START is defined, the control stack, binding stack, and sigalt stack are located wherever mmap finds room for them. Currently only implemented for Darwin, but should work for linux and solaris. We enable this by default on Darwin now. - - - - - 2 changed files: - src/lisp/Config.x86_darwin - src/lisp/x86-validate-darwin.h Changes: ===================================== src/lisp/Config.x86_darwin ===================================== --- a/src/lisp/Config.x86_darwin +++ b/src/lisp/Config.x86_darwin @@ -6,7 +6,7 @@ include Config.x86_common # you have the 10.5 SDK available.
