Terribly slow is still much better than wrong-code. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=9200 --- Comment #3 from jerro.pub...@gmail.com 2012-12-24 16:24:04 PST --- (In reply to comment #2) This is happening in cod3.c REGSAVE::save() and REGSAVE::restore(). Unfortunately, just changing the opcodes doesn't work because MOVAPD requires 16 bit alignment of the operands. Fixing that exposes further problems. Essentially, it'll have to wait a bit. I know nothing about the DMD back end, so this may be an obviously bad idea, but if alignment is the main problem, wouldn't using MOVUPD work in the meantime? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
