For hacking\/prototyping\/fun purposes I have a few embedded systems laying around. For example, I have a couple of Raspberry Pi systems, one of the original Raspberry Pi model B boards and one of the new Raspberry Pi 2 model B boards.<\/p>\n

And on everything, I have the latest Steel Bank Common Lisp<\/a> building.<\/p>\n

On my Raspberry Pi, which is an armv6<\/code> device, I see the following failures in SBCL\u2019s unit tests:<\/p>\n

 Failure:            debug.impure.lisp \/ (TRACE ENCAPSULATE NIL)\n Failure:            debug.impure.lisp \/ (TRACE-RECURSIVE ENCAPSULATE NIL)\n Expected failure:   packages.impure.lisp \/ USE-PACKAGE-CONFLICT-SET\n Expected failure:   packages.impure.lisp \/ IMPORT-SINGLE-CONFLICT\n (62 tests skipped for this combination of platform and features)\n<\/code><\/pre>\n
On my Raspberry Pi 2, which is an armv7<\/code> device, I see the following additional failures:<\/p>\n
 Failure:            float.pure.lisp \/ (SCALE-FLOAT-OVERFLOW BUG-372)\n Failure:            float.pure.lisp \/ (ADDITION-OVERFLOW BUG-372)\n Failure:            float.pure.lisp \/ (ADDITION-OVERFLOW BUG-372 TAKE-2)\n Failure:            debug.impure.lisp \/ (TRACE ENCAPSULATE NIL)\n Failure:            debug.impure.lisp \/ (TRACE-RECURSIVE ENCAPSULATE NIL)\n Expected failure:   packages.impure.lisp \/ USE-PACKAGE-CONFLICT-SET\n Expected failure:   packages.impure.lisp \/ IMPORT-SINGLE-CONFLICT\n (62 tests skipped for this combination of platform and features)\n<\/code><\/pre>\n
This says to me that, contrary to what some have told me, SBCL probably does<\/em> need to distinguish the various ARM instruction set variants.<\/p>\n
Is anyone actually working on SBCL on ARM?<\/p>\n
I also have a DragonBoard 410c<\/a> on the way, and it might be nice to have a fast Lisp on ARM64, though I suspect that\u2019s a bit further out\u2026<\/p>\n","protected":false},"excerpt":{"rendered":"
