Raymond Toy pushed to branch master at cmucl / cmucl Commits: cf7c8acc by Raymond Toy at 2021-01-03T14:19:39-08:00 Address #89: Really remove *scavenge-read-only-space* The previous changes didn't actually completely remove `*scavenge-read-only-space*`. We removed it from the static space, but it's also defined in `code/x86-vm.lisp` so we need to remove it from there as well. And we forgot to commit the boot file, so we're doing that now. - - - - - e7916afe by Raymond Toy at 2021-01-03T22:56:09+00:00 Merge branch 'issue-89-really-remove-scavenge-read-only' into 'master' Address #89: Really remove *scavenge-read-only-space* See merge request cmucl/cmucl!59 - - - - - 2 changed files: - + src/bootfiles/21d/boot-2020-04-1.lisp - src/code/x86-vm.lisp Changes: ===================================== src/bootfiles/21d/boot-2020-04-1.lisp ===================================== @@ -0,0 +1,12 @@ +;; Simple cross-compile script to remove `*scavenge-read-only-space*` +;; which is no longer needed +;; +;; Nothing special needs to be done for the cross-compile.

[Git][cmucl/cmucl][master] 2 commits: Remove scavenging of read-only space.
by Raymond Toy 03 Jan '21

03 Jan '21

Raymond Toy pushed to branch master at cmucl / cmucl Commits: 6af2ad8b by Raymond Toy at 2021-01-03T17:55:43+00:00 Remove scavenging of read-only space. `*SCAVENGE-READ-ONLY-SPACE*` is always set to `NIL`, and it's highly unlikely any one ever sets it. I (rtoy) haven't done that in decades at least. So, remove this static symbol, and remove the C code that tests for this to determine if the read-only space should be scavenged. This requires a very simple cross-compile to remove the symbol. See boot-2020-04-1.lisp for very simple instructions. We currently on do this for x86 since we can't test on sparc right now. Update CI to do a cross-compile.
