concept, or just common implementations? 21:25:55 <|3b|> (like, would using a full parser instead of simple pattern matching help) 21:26:18 needing a peephole optimizer often means your higher level optimizers don't have the right representations. 21:26:30 because they shouldn't have generated those sequences in the first place. 21:26:35 <|3b|> true 21:26:44 Of course, that doesn't mean a peephole optimizer isn't an effective short-term solution 21:27:23 So I'm not saying one shouldn't implement/use a peephole optimizer, just that you shouldn't be happy about having to. :) 21:27:26 *|3b|* supposes you could argue a full parser stops being a 'peephole' pass though 21:41:29 foom: Right. FIXNUM=>FIXNUM LDB with constant byte specifier sucks horribly, as I'm sure you know. 21:43:32 I have one case of a function that does (let ((field (ldb whatever input))) (unless (= field 31) (setf (aref *somewhere* field) something))), which generates some pretty bad code. 21:44:38 INPUT, in this case, is known to be FIXNUM, WHATEVER is five bits wide and somewhere around 21 over, *SOMEWHERE* is well-declared, and so on. 21:45:15 Ideally, the shift part of LDB should be deferred until /after/ the conditional in the UNLESS is evaluated. 21:46:20 Can we even represent a type for (ash (unsigned-byte 5) 21) or so? 22:17:07 *pkhuong* is with foom. 22:17:26 a peephole basically means you're doing it wrong, but since it's pretty much impossible to do it right... 22:24:40 nyef: yes, byte-with-a-bite-out I think 22:26:16 mm, no, that's not quite the same thing 22:26:25 so maybe not 22:27:13 Hrm. 22:27:50 I'm already unconvinced about the way the compiler deals with floats, anyway. What's integers to add to that list? 23:03:47 -!- tcr [~tcr@217-162-131-235.dynamic.hispeed.ch] has quit [Ping timeout: 255 seconds] 23:23:58 hargettp [~hargettp@pool-71-184-182-139.bstnma.east.verizon.net] has joined #sbcl 23:31:34 -!- hargettp [~hargettp@pool-71-184-182-139.bstnma.east.verizon.net] has quit [Quit: Leaving...] 23:45:59 hargettp [~hargettp@pool-71-184-182-139.bstnma.east.verizon.net] has joined #sbcl
