From: Andi Gutmans Date: Wed, 8 Sep 2004 22:14:12 +0000 (+0000) Subject: - Some architectural changes: X-Git-Tag: PRE_NEW_VM_GEN_PATCH~359 X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8eb8850c907040b2dbf3e4e8abbd1f6869bed457;p=php - Some architectural changes: a) We specialize opcodes according to op_type fields. Each opcode has to be marked with which op_type's it uses. b) We support different execution methods. Function handlers, switch() and goto dispatching. goto seems to be the fastest but it really depends on the compiler and how well it optimizes. I suggest playing around with optimization flags. - Warning: Things might break so keep us posted on how things are going.
