Raymond Toy pushed to branch master at cmucl / cmucl Commits: 952c3759 by Raymond Toy at 2021-01-03T15:33:35-08:00 Fix #90: Remove unused FP static symbols on x86 We no longer support x87, so the static symbols for the long float constants aren't used anymore.

[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.
