#156: Readtime macro compiler error -----------------------+---------------------------------------------------- Reporter: mevenson | Owner: ehuelsmann Type: defect | Status: closed Priority: blocker | Milestone: 0.26 Component: compiler | Version: Resolution: fixed | Keywords: ironclad -----------------------+---------------------------------------------------- Changes (by mevenson): * status: new => closed * resolution: => fixed Comment: r13380 allows compilation to succeed, but the compiled code is suboptimal. The ABCL compiler currently dumps such forms in their READ form to be read at load time rather than constructing JVM code to initialize the value. This has two consequences for your usage here: first, since the string has to be derserialized by the Lisp reader there is almost no conceivable JVM implementation that will make this usage faster. And the potentially more serious problem is that since the Lisp reader syntax doesn't specify the underlying array type, at runtime one gets an array who's BASE-ELEMENT- TYPE is T rather than (UNSIGNED-BYTE 32) which is probably less efficient. Closing the ticket, as the immediate bug has been addressed to the old behavior. -- Ticket URL: <http://trac.common-lisp.net/armedbear/ticket/156#comment:4> armedbear <http://common-lisp.net/project/armedbear> armedbear
